Firstly, the nature of the material will affect the output of the Raymond Mill. The greater the hardness of the material, the greater the rolling pressure generated by the grinding roller on the grinding ring, and the more serious the wear of the equipment, so the production of the equipment The smaller the capacity, the lower the finished product output. Also, when the humidity of the material is too large, it is easy to produce fine powder adhesion during the grinding and milling process, reducing the production efficiency of the Raymond mill, causing equipment blockage at the air duct, analyzer, and discharge port, and the yield of the finished product. The design requirements cannot be met. When using the Raymond mill for fine powder production, there are certain requirements for the fineness of the finished product. When the fineness of the finished product is finer, the Raymond mill is required to carry out the production work for a long time, so the production efficiency of the equipment is low, the production capacity is small, and the output of the finished product is affected to some extent. The Raymond mill achieves the fine powder production of the material by the grinding roller on the grinding ring. Therefore, the better the quality of the grinding roller and the grinding ring as the wearing parts, if the grinding roller rings are severe after a short time of use. Wear and tear, the material can not achieve sufficient grinding effect. The efficiency improvement of Raymond Mill will become an important part of saving resources and energy. Today's mining machinery mill industry has passed the advantage of low labor force, conforming to the international low carbon development trend, and the rapid development of the industrial milling industry market. As well as the country's increased demand for energy conservation, environmental protection and consumption reduction, the Raymond mill will affect the output of the equipment if it is used improperly.

Smokeless cigarettes are quickly becoming the greatest replacement for tobacco cigarettes: perhaps even being a more common substitution and alternative than quitting smoking all together, which is what many non-smokers wanted Marlboro Cigarettes For Sale, but once smokers found out about smokeless cigarettes, many felt it was worth giving them a shot just to see if they even slightly resembled the real thing. At first glance, smokeless cigarettes, which are regularly known as electronic cigarettes and e-cigarettes, look almost identical to real cigarettes: they were created to look just like the real thing, down to the tiniest tip: literally Cheapest Marlboro 100 Cigarettes. The tip of smokeless cigarettes even have a little, tiny orange light that lights up every time a smoker takes a drag, and a water vapor that's odorless comes out of the end of smokeless cigarettes when the smoker takes a drag. Therefore, from far away, it would be hard to tell the difference. It's only if you were up close that you'd notice the absence of the smell of cigarette smoke, and that smokeless cigarettes are made of a hard, durable material. Smokeless cigarettes have two basic parts that makes them up: the main mouthpiece, which is what the smoker takes their drags on, and this has what some call a vaporizing chamber in it Wholesale Newport Cigarettes In Usa, which is comprised of a very small atomizer and a battery that runs the entire little 'smokeless factory.' This piece is attached to electronic cigarette refill cartridges, which are filled with e-juice, a liquid that's made with nicotine and a chemical that helps the liquid to turn to vapor, which it does when a smoker takes a drag and the e-juice is sucked into the atomizer, where it turns into a vapor that the smoker inhales just like real cigarette smoke. The e-juice in the electronic cigarette refill cartridges comes in a variety of different flavors and strengths, so smokers can buy e-juice in flavors as crazy as blueberry or even chocolate; certainly something traditional cigarettes don't offer. The e-juice for electronic cigarette refill cartridges is also available in different nicotine strengths, from mild to strong, and there's even e-juice without any nicotine at all! When a smoker has used up all of the e-juice for their smokeless cigarettes Newport Cigarettes Website, they need to buy electronic cigarette refill cartridges, which is available in a couple different styles; either disposable or refillable. Electronic cigarette refill cartridges are like the tobacco filled part of a cigarette: the most important part besides the battery Wholesale Newport Cigarette Store, so if you do decide to switch, always make sure you have an e-juice filled cartridge handy!

How to illuminate the optical lens General purpose lighting: General lighting generally uses ring or spot lighting. The ring light is a common general illumination method that is easily mounted on the high purity YVO4 laser crystal to provide sufficient illumination for the diffuse surface. Backlighting: Backlighting is the placement of an optical lens on the back of an object relative to the camera. This kind of illumination is very different from other illumination methods because the image analysis is not the water but the incident light. Backlighting produces a strong contrast. Surface features may be lost when applying backlighting. For example, a backlight technique can be applied to measure the diameter of a coin, but it is impossible to determine the front and back of the coin. Coaxial lighting: The coaxial illumination is that the light having the same direction as the axial direction of the camera illuminates the surface of the object. Coaxial illumination uses a special semi-reflective specular reflection source to the lens axis of the camera. The semi-reflective mirror only allows the optical lens that reflects perpendicular to the lens from the surface of the object to pass. Coaxial illumination technology is useful for uniform illumination of flat surfaces with mirrored features. In addition, this technique can also achieve a partial highlighting of the surface angle change, since light that is not reflected perpendicular to the surface of the camera lens does not enter the lens, resulting in a darker surface. Continuous diffuse illumination: Continuous diffuse illumination applied to the surface of the object for reflection or complex surfaces with complex angles. Continuous diffuse illumination uses a hemispherical uniform illumination to reduce shadow and specular reflection. This type of illumination is very useful for fully assembled board lighting. This optical lens can achieve uniform illumination in a range of 170 solid angles. Dark field lighting: Dark field illumination provides low angle illumination relative to the surface of the object. Use the camera to take the mirror so that it is in its field of view. If the high precision YVO4 laser crystal is visible in the field of view, it is considered to illuminate the bright field. Conversely, the optical lens is not visible in the field of view. Therefore, whether the light source is a bright field illumination or a dark field illumination is related to the position of the light source. Typically, dark field illumination is applied to illumination of a portion of the surface portion that has a raised portion of the illumination or surface texture. Structure light: Structured light is a type of light (such as a line, a circle, or a square) projected onto the surface of an object. Typical structured light involves laser or fiber optics. Structured light can be used to measure the distance from the camera to the optical lens. Multi-Axis Illumination: In many applications, multiple illumination techniques are required in order to differentiate different features in the field of view.

The optical lens is a key component in the machine vision system. Its essential function is to convert the optical signal into an ordered electrical signal of the AFT-808 small high-definition customizable large size optical prism. The optical lens is generally installed on the machine line instead of the human eye for measurement and judgment, and is converted into an image signal by the digital image pickup target and transmitted to a dedicated image processing system. The image system performs various operations on these signals to extract features of the target, and then controls the action of the device on the spot according to the result of the discrimination. Compared with traditional civilian cameras, optical lenses have high image stability, high transmission capacity and high anti-interference ability. Most of the optical lenses on the market are based on CCD (Charge Coupled Device) or CMOS (Complementary Metal Oxide). Semiconductor) chip camera. CCD optical lens is a commonly used image sensor for machine vision. It integrates photoelectric conversion and charge storage, charge transfer, and signal reading. It is a typical solid-state imaging device. The outstanding feature of CCD cameras is the use of charge as a signal, unlike other devices that use current or voltage as a signal. Such an imaging device forms a charge packet by photoelectric conversion, and then transfers and amplifies the output image signal under the action of a driving pulse. A typical CCD camera consists of an optical lens, timing and sync signal generator, vertical driver, and analog/digital signal processing circuitry. As a functional device, CCD camera has the advantages of no burn, no hysteresis, low voltage operation and low power consumption compared with vacuum tube. The development of CMOS camera image sensors began in the early 1970s. In the early 1990s, with the development of VLSI manufacturing process technology, CMOS camera image sensors were rapidly developed. The CMOS camera image sensor integrates a photosensitive element array, an image signal amplifier, a signal reading circuit, an analog-to-digital conversion circuit, an image signal processor, and a controller on one chip, and has the advantage of program random access of local pixels. CMOS camera image sensors are widely used in high resolution and high speed applications due to their good integration, low power consumption, high speed transmission and wide dynamic range. In addition, sale of custom optical prism assemblies can be divided into: According to the structural characteristics of the sensor can be divided into line array camera, area array camera; According to the scanning method, it can be divided into an interlaced scanning camera and a progressive scanning camera; According to the resolution, it can be divided into ordinary resolution camera and high resolution camera; According to the output signal method, it can be divided into analog camera and digital camera; According to the output color, it can be divided into a monochrome (black and white) camera and a color camera; According to the output signal speed can be divided into ordinary speed camera, high speed camera; According to the response frequency range, it can be classified into a visible light (ordinary) camera, an infrared camera, an ultraviolet camera, and the like.

Essentially, that’s what Swiss Breitling has done in their Breitling for Bentley series; taken all the best qualities from both brands, and combined them to make high-performance machines for the wrist.The watch uses the in-house calibre B06, which draws inspiration from robust and powerful Bentley engines, and offers a power reserve of 70 hours, as well as being COSC certified. The watch features a 30-second chronograph system, which is capable of telling the time to 1/8th of a second-the perfect watch for lovers of style, speed and accuracy.Capturing the spirit of naval aviation, the watch is designed to feel perfectly at home amid the anon-stop intensity aboard the deck of an aircraft carrier. The constant, perfectly regulated choreography of planes taking off and landing. The alternating rhythm of catapults and arresting cables, amid clouds of steam.It was probably inevitable that Breitling would eventually do it, and so it has. The watchmaker has just announced a faithful remake of the first generation Navitimer, the pilot’s chronograph equipped with a slide rule bezel that’s the quintessential Breitling. The new Breitling Avenger Watch features a light, ultra-sturdy titanium case, a favorite metal in the field of aviation due to its strength and lightness. The 45mm diameter is enhanced by protective lateral reinforcements; its satin-brushed finishes eliminate any undesirable glinting in the heat of action. The dial is distinguished by its gray color with tone-on-tone counters accentuated by a finely snailed raised motif; it features macho aviation-inspired stencil-type numerals, with the luminescent coating ensuring excellent visibility. The dial is also protected by a thick sapphire crystal, glare-proofed on both sides. cheapest patek philippe There was once a time when you could keep your shoes on at airport security, and budget airlines had yet to be invented. In hindsight the golden age of commercial aviation was a brief one, just three decades or so after the second world war. Three giants of the jet age were Pan American World Airways, Trans World Airlines, and Swissair, once great airlines that have all gone ignominiously bust. The Curtiss P-40 Warhawk was a workhorse flown by the Allied air forces, mainly in Asia and Africa, most famously by the First American Volunteer Group of the Chinese air force, better known as the “Flying Tigers”, a unit made up of American volunteer airmen.And the dial has a glossy black finish with ivory-tone Super-Luminova. The winged shield at 12 o’clock is actually the logo of the Aircraft Owners and Pilots Association (AOPA), but sans “AOPA” within. This is how it was on watches sold in Europe; only timepieces destined for America, the home of the AOPA, had the complete logo.The steel case is 40.9mm in diameter and 13.43mm high, with the same slim case band and faceted lugs as the original. More crucially, the bezel has a “beads of rice” edge made up of 94 beads, just as it was in 1959 (although the number varied across the years). While the aesthetics are unchanged, the case has a useful 30m water-resistance rating. richard mille bubba watson jacob & co astronomia tourbillon Depending on who you are and your perception of the message on the rear of this watch you’ll either love it or hate it. When it comes down to it, this is Breitling banking on the power of iconography to push this piece to the patriotic US consumer. Would it be cool to have a Breitling watch with the Great Seal of the US on the back? Sure. Would I pay a handsome premium for it? Not sure. Another carrot is that sales proceeds of the 50 watches will go to benefit the Fischer House Foundation charity.A few years ago the Chronomat 44 watch came out and contained Breitling’s first in-house made movement called the Caliber 01 chronograph automatic. 44mm wide and in Breitling’s lovely polished steel case, this watch serves as a fitting base for the limited edition. This model with its black textured dial and red accents is a real handsome piece. The case and dial design are aging very gracefully and this is truly a handsome piece. Breitling men’s watch is actually one of the only brands that does make watches simply too large for my wrists, and I almost never say that. This 44mm wide version of the Chronomat isn’t one of them however. “Over the past twenty-five years, we have watched Breitling transition from its ‘infancy’ to a horological superpower with a true cult following,” Third generation President & CEO of Govberg Jewelers Danny Govberg said. “We are honored to celebrate the Breitling collector community with such an exceptional timepiece.” For Govberg, this Breitling watch is “for the fans.” ulysse nardin freak You would be correct in associating Breitling watches with aviation but its dive watches are as formidably endowed as their airborne counterparts. The Avenger II Seawolf Blacksteel dive watch is a monster of the abyss capable of plunging to depths of 3,000 metres -10,000 feet- a watch suited for saturation or extreme diving. Equipped with a helium escape valve, the Avenger II Seawolf comes in a beefy 45mm steel case, covered with an ultra-resistant black carbon coating and a bright ‘cobra yellow’ dial with large luminescent hour indices and hands. Fans of Breitling’s macho tone, refined aesthetics, and hearty build will likely find the new Breitling Avenger Bandit watch satisfying. You won’t confuse many other watches for a Breitling Mens Watch, but you sometimes have to look closely to distinguish between the models themselves. In other words, the brand has a strong and distinct identity, and this Breitling Avenger Bandit is heavy on that DNA. This latest iteration of the Avenger seeks to bring a “stealth” look to the line, and it’ll no doubt appeal to those who like a brooding, darker watch but may not want the all the black that comes with one of the Breitling Avenger Blackbird watches. hublot mp-05 laferrari In the smartwatch category, Breitling Exospace B55 made its first appearance as one of the most luxurious watches. The watch has not yet been announced officially, but has had a teaser floating around in the Internet for the users who like to integrate fashion with technology.The new watch is powered by the exclusive new multifunction Breitling Caliber B55, a SuperQuartz movement ten times more accurate than standard quartz. It is chronometer certified by COSC, ensuring precision, reliability and performance. It also includes an electronic tachymeter, a chronograph recording up to 50 split times and a countdown/countup system that is useful in enabling a sequence of countdown and timing operations. Enhanced performance was the name of the game in this case, and that was the core driver for the brand in developing its first ever connected chronograph. And just like all the other big player of Swiss mechanical watchmaking seem to emphasize when they go connected, this is also billed as a watch first and a smart device second. In this case, the chronograph remains the master, and connectivity is primarily designed to improve the functionality of the wristwatch. http://www.watchgetluxury.com

Digital camera imaging principle: the detected object reflects light, and is refracted by the custom high purity LBO nonlinear crystal to generate an analog current signal on the photosensitive sensor (CCD or CMOS). This signal is converted to a digital signal by an analog-to-digital converter and then transmitted to the image processor to obtain The image is then passed to the computer via the [Optical Lens] communication interface for subsequent image processing analysis. The imaging principle is summarized as shown below. Since the electrical signal generated by the photosensitive element is too weak and a large amount of voltage loss is generated in the process, the analog-to-digital conversion cannot be directly performed. Therefore, the output data must be uniformly amplified. This task is performed by the CCD sensor. The amplifier is specifically responsible for, after processing by the amplifier, the electrical signal strength of each pixel is increased by the same amplitude; since the signal is amplified by only one amplifier, less noise is generated. Since the CCD camera itself cannot convert the analog signal directly into a digital signal, it also needs a special analog-to-digital conversion chip for processing, and then outputs it to a dedicated DSP processing chip in the form of a binary digital image matrix. CMOS camera working principle: CMOS is the abbreviation of complementary metal oxide semiconductor. Each photosensitive element in CMOS sensor directly integrates amplifier and analog-to-digital conversion logic. When the photodiode receives illumination and generates analog electrical signal, the electrical signal is first The amplifier in the photosensitive element is amplified and then directly converted into a corresponding digital signal. In other words, in a CMOS sensor, each of the photosensitive elements can produce a digital output, and the resulting digital signals are combined and sent directly to the DSP chip for processing. The problem occurs precisely here, and the amplifiers in the CMOS photosensitive elements are analog devices. There is no guarantee that the magnification of each image point will be strictly consistent, so that the enlarged image data cannot represent the original appearance of the captured object - reflected in the output of the latter, that is, a large amount of noise appears in the image, and the quality is significantly lower than that of the CCD sensor. However, the current technology in this area has been greatly improved. Since the CCD is a unified amplification of the signal, the noise is small, and the CMOS is separately amplified by the signals of the respective photosensitive components, resulting in a large noise, but the advantages of the CMOS sensor are large resolution, low cost, small size, etc. Currently at industrial related exhibitions, It is unsightly to see the figure of CCD, and it also shows that CMOS will be the mainstream of future high quality Chinese BIBO nonlinear crystal sensors. The main differences between CCD cameras and CMOS cameras are summarized in the following table: Black-and-white optical lens imaging principle: Taking a black-and-white optical lens with 8-bit data depth as an example, each pixel converts the light intensity into 256-level data, black is recognized as "0", and white is recognized as "255", thus each will The light intensity received by each pixel is converted into numerical data, that is, a gray value. A black and white picture is a checkerboard arranged in pixels and stored as a combination of a series of ordered gray values. Color optical lens imaging principle: The imaging mode of the color optical lens has a 3-chip mode and a bayer mode. 3 chip mode: The prism is used to divide the incident light into three beams. Each beam of light is filtered by a different built-in grating to extract one of the three primary colors, and then respectively sensitized by using three CCDs. These images are then combined to produce a high resolution, color accurate image. This method requires three photosensitive chips and is relatively expensive to manufacture. Bayer mode: Bayer mode was proposed by Mr. Bayer, and only one image sensor is used to solve the color recognition. His approach is to set up a filter in front of the image sensor, which is covered with filter points, one-to-one correspondence with the pixels below. That is to say, if the sensor is 1600x1200 pixels, then there are 1600x1200 filter points on the upper layer. Each filter point can only pass one of red, green and blue, which means that there are only four colors in the lower layer of the pixel: red, green, blue, black (indicating that no light passes) . The arrangement of the filter points on the Byer filter is regular: around each green dot, there are 2 red dots, 2 blue dots, and 4 green dots. Since the human eye is more sensitive to green, the green is twice as much as red and blue. Light is synthesized into a color image by a Byer filter with only three colors, which requires a later algorithmic processing - adjacent interpolation. Taking yellow light as an example, it is a mixture of red and green light. After passing through the filter layer, the pixels below the red dot and the green dot will have values, but the pixels below the blue dot have no value, so look around a pixel. The color distribution -- red and green, but no blue -- can be inferred that the original color of this pixel should be yellow. This method of calculating color is called "demosaicing." The lower part of the figure below is the "mosaic" image generated by the image sensor. All the pixels are only red, green, blue and black. The upper part is the effect of "de-mosaic". This is the result of algorithm processing. . The original mosaic image is the raw format. Optical lens imaging is divided into black and color. The difference in imaging color is closely related to the sensor chip (CCD/CMOS). CCD optical lens working principle: customized large size and special shape CaF2 optics is the abbreviation of charge-coupled device. After the photosensitive image point receives illumination, the photosensitive element generates corresponding current, and the current magnitude corresponds to the light intensity. Therefore, the electrical signal directly output by the photosensitive element is simulated. In the CCD optical lens sensor, each photosensitive element does not further process this, but directly outputs it to the next register, and outputs the analog signal generated by the component to the third register, once analogy, knowing the combination A register can be used to form a uniform output.

To understand the performance of wholesale infrared Germanium lenses, it is necessary to understand what is the EMVA1288 standard. The EMVA 1288 full name, the European Machine Vision Association 1288, is a set of performance characterization standards for image sensors and cameras developed by the European Machine Vision Association. Quantum efficiency η Transient dark noise (Dark noise) ***Absolute sensitivity threshold Dark signal non-uniformity (DSNU) Quantum efficiency: the ratio of the number of electrons produced by a camera chip to the number of photons received, which can also be said to be conversion efficiency. Quantum efficiency is related to the ability of an optical lens to respond to multiple faint light. "Dark noise" refers to a signal produced by the thermal excitation of electrons from the read and amplify circuits when there is no illumination and the exposure time is zero. Obviously, the wholesale large size infrared Silicon optics only wants to get the electronic signal generated by the photon, which is undesirable for the camera. Dark noise affects many other characterization projects and largely determines the quality of the camera. *** Sensitivity threshold is a very intuitive performance characterization that directly tells us how much the camera will produce a numerical signal when the number of photons hitting the optical lens is reached. "Dark signal non-uniformity" refers to the difference in the dark signal generated by the thermal excitation of each pixel on the camera chip. This reflects the level of the chip manufacturing process. Theoretically, the dark signal generated by each pixel should be the same. . For us, if we can know the "underlying cornerstone" - the number of photons and the "top building" - the value of the digital signal, we can find the intermediate parameters according to the relationship. The expression for the number of photons is: 1.A is the effective area of ​​the pixel, and the international unit is square meter. 2.E is the irradiance, the international unit is watts per square meter. 3.t is the exposure time, that is, how long the camera has received 4. The Et multiplication, ie the total energy energy of the photon per unit area, multiplied by the area A, then the physical meaning of the numerator of the expression is the total energy of the photons received in the pixels of area A during the exposure time t. 5. For monochromatic light of frequency v, the energy of a single photon is e = hv, then the energy of dividing the total energy by a single photon is equal to the number of photons. 6. The digital signal value can be used to measure the gray value of each pixel by computer. The summary of the measuring device to be measured and the corresponding is summarized as follows: 1. Irradiance E - Irradiance meter 2. The pixel "effective" area A - given by the CCD itself data 3. Exposure time t - controlled by the camera's software 4. The frequency or wavelength of light - determined by the light source 5. Digital signal value (gray value) - read by computer software Select purchasing large size ZnSe optics matching light source and its accessories: several requirements for light source 1. Must be "uniform light". The meaning of uniform light is that the "irradiance" or light energy of each point is the same at the same vertical distance from the illumination source. The image sensor contains a lot of pixels (typically 2048*2048), and the performance parameters represented represent the overall performance of the camera. Therefore, the same light should be given to each pixel on the camera to eliminate the difference in illumination. The resulting performance difference. In order to obtain uniform light, the high-quality method is to use an integrating sphere, and place the LED lamp on the integrating ball into the optical port. After the incident light is reflected multiple times inside the integrating sphere, uniform light will be formed at the light exiting port. The radius of the light exit port should be larger than the size of the CCD, but it should not be too large, otherwise the uniformity of the emitted light cannot be guaranteed. 2. For black and white optical lenses, monochromatic light should be selected, and the wavelength of the monochromatic light should be the wavelength corresponding to the large sub-efficiency of CCD/CMOS. This is because what we want to represent should be the ideal performance of the camera, and the greater the quantum efficiency, the better the performance. In general, for different CCDs, we can choose a single red LED light (LED is the abbreviation of light-emitting diode, corresponding to wavelength 625 nm), or green LED light (corresponding to wavelength 525 nm) color camera, white light, Because color cameras contain three colors, R, G, and B, the light source should also contain these three colors, so white LEDs can be used. The quantum efficiency measured at this time is obviously the average quantum efficiency of the CCD full-band. 3. The accessories that control the irradiance of the light source or light are DC stabilized power supply and diaphragm. Wherein, the DC stabilized power supply is used to control the voltage (or current) of the LED lamp bead, thereby changing the irradiance of the outgoing light; and the pupil is located in the integrating sphere, and the incident in the integrating sphere can be changed by changing the size of the pupil. The amount of light thus changes the irradiance of the outgoing light. In actual testing, these two methods can be used to regulate.

The water leakage caused by the material characteristics of the hot sale color-coated corrugated roofing sheet roof leakage. 1. Construction factors a. During the construction process, the corrugated roofing sheet is not protected, and the roof is arbitrarily stepped on, which destroys the flatness of the roof and even the potholes. b. Because the span of the steel structure factory is too large, in many cases, there is a lap joint process in the roof panel. Although the sealant and the rivet are used in the lap joint, the installation is often difficult to reach the design theory standard, resulting in leakage. rain. c. Some color steel gutters are not preserved. Some construction units' gutter anti-corrosion is only brushing anti-rust paint or asphalt paint. After using for a period of time, the gutter is seriously corroded and even rotted and deformed. 2. Use factors a. The house increases the load at will during use, causing the color steel plate to deform. In particular, the load is arbitrarily increased on the roof rafter, and the rafter is deformed, resulting in water in the house area. b. Waterproof glue and sealant are aging, and the necessary maintenance is lack of use.

In recent years, companies that often do machine vision precision measurement will hear some newer terms, such as bilateral telecentric lenses, one-sided telecentric lenses, telecentric lenses, square telecentric lenses, etc. The optical concept that is not often mentioned is very confusing. I don’t know how to understand it. The collected information is often not highly specialized. It is a practical point of view to explain the relevant principles of wholesale infrared Germanium lenses. Convex lens imaging principle Feature 1: All light passing through the optical center does not change its direction of propagation Characteristic 2: The convex lens has a converging effect on the parallel light, and the imaging of the lens utilizes this. Optical lens imaging principle Principle: By placing the diaphragm in the middle of the lens, the light entering and exiting the optical lens is parallel light, and other light is blocked by the diaphragm, and cannot reach the imaging chip. Each side is an object-distance, square telecentric optical lens. . The object side solves the problem of depth of field and solves the problem of magnification change. Problems solved by optical lenses Resolution problem: The resolution of ordinary optical lens can't keep up with the improvement of chip resolution. It is subject to the principle of optical imaging. It can only be achieved by 10um or so. It can be used with optical lens of 1000W pixel. It can't be satisfied. High resolution cameras and high precision measurement inspection requirements. Depth of field problem: The depth of field of a normal lens is relatively small. When an object to be measured is out of range in the depth direction of the lens, detection or measurement cannot be performed. Magnification problem: Magnification changes as the distance changes. This feature can lead to intolerable errors when our vision system is used to perform precision measurement tasks. FAQ & Q & A Q: Why is the size of the optical lens usually large? A: Because the double telecentric lens is parallel light in and out, so how much shooting area is needed, how much parallel light is needed to enter, so how large the lens barrel is needed, so the double telecentric lens is usually large in size and field of view. The bigger the volume, the bigger the volume. Q: How to choose the optical lens? A: Mainly pay attention to the following points: field of view, compatible CCD target surface, interface type, etc. meet other requirements, such as working distance, depth of field range, external dimensions, etc. as long as it does not affect the use. Q: What kind of light source is better with purchasing large size ZnSe optics? A: Since the telecentric lens only accepts parallel light, it filters out almost all the diffuse light sources, so the imaging is dark in the natural environment, so the parallel light source can be used to limit the advantages of the double telecentric lens. The edges of the object are clear and stable, and the noise during the detection process is effectively removed.

The consumption of electricity of grinding mills in the dressing plant is considerable; it is about 30% to 70% of the total power consumption of the whole plant. Generally speaking, the electricity consumption can be divided into three aspects: 1.The useful energy consumption is used for the movement of the grinding medium. It is relate to the quality of the grinding medium and the ration speed of the grinding mill . This consumption is about 75% of the total power consumption of the sand processing plant. 2. The electricity loss of the motor itself is about 5%-10% of the whole power consumption. It is related to the efficiency of the motor. 3. The friction loss of machine. It is include the sound energy consumption, heat loss consumption and the rotation loss of the machine.

Ball mill is the key equipment to smash the raw material. It is widely used in cement, silicate products, and new building materials, refractory materials, fertilizer, black and non-ferrous metal processing and glass ceramics production industry. It can be used for the dry or wet grinding progress to grinding a variety of ores and other grind-able materials.

The ball mill is composed with the horizontal cylinder, hollow shaft and the grinding head. The long cylinder is equipped with quartz grinding plant medium. Steel cylinder is fixed with steel liner. The grinding of steel generally spheres, according to different diameters and a certain percentage of loads, grinding media steel section can also be used.

According to the particle of the material, the material will enter into the cylinder through the hollow shaft which is on the feeding end. When the cylinder is turning, because the inertia and the centrifugal force, the material will be bring to a certain height and fall down via the action of gravity. During the dropping process, the material will be crushed in the cylinder.
