The roller crusher is a Quarry crusher that is widely used in many industries. In order to ensure maximum crushing capacity for the roller crusher, it is necessary to operate the roller crusher in accordance with the correct use and maintenance methods. 1) Before starting the equipment, the operator should carry out a comprehensive inspection of the equipment, including the bolt fastening of each part, the oil level of the reducer and the lubrication of the bearing. 2) The crusher should start at no load and reach the normal speed without abnormal conditions before starting the feeding. Before the normal shutdown, the feeding should be stopped first, and the material in the crushing chamber should be drained before the machine can be shut down, except for special circumstances. Load start is not allowed. 3) After long-term decommissioning or before initial start-up, the crusher should be thoroughly inspected to see if the bolt is loose, whether the gearbox meets the requirements, sufficient lubricating oil, whether the bearing is filled with grease, whether the wiring of the electric circuit and the control switch is wired. Correct, the wiring is loose, and the material in the crushing chamber has been removed. After confirming the correctness, jog the start of the crusher and observe whether the crusher is running in the correct direction before it can be officially started. 4) In the use, it is found that the Zenith Crusher Product has abnormal sound. When the transmission unit or oil has abnormal temperature rise or smells, stop it in time, find out the cause and eliminate the fault before restarting. 5) The motor bearing and main bearing of the crusher are cleaned and cleaned once a year; the reducer is cleaned and oil changed once a year. 6) When repairing the crusher, first cut off the power supply and hang up the inspection mark to ensure the safety of the maintenance personnel. 7) After the crusher is operated for 3 months, the fasteners should be retightened once and regularly maintained and repaired, mainly including weekly inspection, monthly inspection and annual inspection. Weekly inspection: Check the bolts and nuts of each part for looseness every week, whether the electrical wiring is damaged, the working condition of the reducer and the motor. Monthly inspection: Check the wear of the broken teeth at least once a month. Annual inspection: It is required to carry out comprehensive inspection of the crusher, remove and wash the bearings of the motor, reducer and crushing roller, clean the waste lubricating oil in the crusher, check the wear of the transmission parts, and replace it if it is severely worn. 1 time. After disassembling the body, when reassembling, a layer of sealant must be evenly applied on the joint surface of the upper and lower bearing housings and the static joint surface of the body to prevent oil leakage on the sealing surface.

Grinding wheel made in China use precautions side grinding problem In the daily use of the grinder, we often find that some operators do not divide the type of grinder, regardless of the type of grinding wheel, and use the side of the grinding wheel to grind it arbitrarily. This is a serious violation of the safety operation rules. behavior. According to the regulations, the grinding wheel with the circumferential surface as the working surface should not be ground. The radial strength of the grinding wheel is large and the axial strength is very small. When the operator is too strong, the grinding wheel will be broken and even hurt. In practice, This behavior should be prohibited during use. Positive operation problem In daily use, many operators are always accustomed to working on the grinding wheel made in China because the direction can be used. In fact, this behavior is a special prohibition in the operation of the grinder. According to the operating procedure, when grinding the workpiece with a grinder, the operator should stand on the side of the grinding wheel and must not operate on the front side of the grinding wheel to avoid the grinding wheel flying out or the grinding wheel breaking out and injuring people when the grinding wheel fails. Hard operation problem In the use of grinders, some operators, especially younger operators, are trying to grind quickly and use too much force, which is a very unsafe operation. The flatness of any grinding wheel made in China has a certain strength, which is likely to cause the grinding wheel to break, or even fly out and hurt people, it is also a behavior that should be prohibited.

The cutting blade is the main tool for grinding and is a porous object composed of abrasive and binder. Among them, abrasives, binders, and pores are the three basic components of the customized metal cutting disc. With the different manufacturing processes of abrasives, binders and dicing sheets, the characteristics of the dicing sheets may vary greatly, which has an important influence on the precision, roughness and production efficiency of the grinding process. Therefore, it is necessary to select a suitable cutting piece according to specific conditions. Yongkang Jinlida Electromechanical Abrasives Manufactory is a small and medium-sized manufacturer specializing in the production of cut pieces. It is loved by customers. Now it has distributed agents all over the country, and many foreign trade orders have been completed. The products are widely known. Jinlida produces a variety of suitable cutting sheets. The whole factory has more than 130 kinds of specifications, which can meet the requirements of most customers for cutting sheets, whether it is cutting sheets, grinding sheets or hundreds of impellers. Dry abrasive or wet grinding can be used for grinding of superabrasive cutting blades. However, the use of wet grinding not only extends the life of the cutting piece but also prevents the workpiece from being burnt. Different grinding fluids will make the cutting ratio of the cutting disc several times or even ten times different. The degree of mechanical wear, chemical attack and thermal damage of the cutting piece during the grinding process is closely related to the cooling effect. However, when using CBN cutting sheets for wet grinding, it should be noted that CBN reacts with water vapor and oxygen in the air at high temperatures to form ammonia and boric acid (BN+3H2O→H3BO3+NH3). This reaction is called hydrolysis. Accelerate the wear of the cutting piece. Therefore, water-soluble oils or aqueous solutions with extreme pressure additives are often used in use to attenuate the hydrolysis. When the cutting piece is wet-milled with different grinding liquids, the relative life of the CBN cutting piece is different, the cutting piece cooled by pure oil has the longest life, the life of the water-soluble oil-cooled cutting piece is second, and the cutting piece cooled by water and the anti-rust additive is used. The life expectancy is the lowest.

The ZENITH 1214 counter-type sand making machine is driven by a motor with a power of 132 kW. The hammer in the crushing chamber breaks the stone entering from the upper inlet by the rotational force. The operation warning sign on the counter-type sand making machine and the contact number of our company: 0371-67315555 If the rotating part of the counter-type sand making machine motor is unbalanced, it will make the whole motor vibrate when rotating. Vibration causes damage to the bearings, the feet and the motor itself. In order to eliminate the vibration, the rotating part should be balanced. The balance is divided into static balance on the prism and balance of the balance of the part when rotating. The centrifugal force generated by the rotation of the rotor of the sand making machine motor is large, which will generate pressure on the bearing and cause vibration of the motor. Such an imbalance can be eliminated by static equilibrium on the prism. The journal of the rotor's bearing is placed on a carefully calibrated horizontal prism, which of course is the heavy half that is turned downwards. Put such a heavy lead block in the special groove above, so that the prism of the rotor can stay in any position. After the balance is good, the lead block is usually replaced by the same heavy steel block, which can be safely welded to the rotor or nailed to the rotor.

The development direction of China grinding abrasive disc, the development trend of diamond grinding disc. Today's gear grinding machine has improved a lot more than the same type of machine tool ten years ago. This comes from a series of major improvements: Many gear grinding machines are more accurate due to the onboard measurement system. Because the machine is used for measurement, it is not necessary to remove the gear from the workbench and send it to other places for inspection, which avoids the secondary installation error during rework. During processing, the gear is first analyzed by the onboard measurement system, and the measured parameters are compared with the theoretical design parameters to determine the required correction amount. After the control system collects these correction data, the grinding gear processing state is automatically adjusted, and then the grinding is performed. And measurement. Repeat the cycle until the required accuracy is reached. The integrated onboard measurement and onboard correction system make modern gear grinding machines more efficient. In recent years, the use of compact direct drive motors on China grinding abrasive disc spindle and gear workpiece spindles has increased. The direct drive spindle avoids drive chain errors. Therefore, the use of direct drive motor in the "repair disc-grinding gear" cycle, coupled with a better grinding disc and multi-axis linkage control, can eliminate the high-frequency error and harmful vibration of the cutting pattern, the geometrical shape of the distortion, the noise of the gear. The term “automation” is increasingly used in gear grinding, especially in process production, including workpiece mounting, tool change, and inventory sorting in synchronization with workpiece processes. Automation eliminates machine idle time and helps reduce waiting time between processes.

The guide rail is the most important support component in the machine. Its processing accuracy directly affects the working accuracy of the machine. However, the guide rails are mostly hollow thin-walled parts that are cast and have a complicated structure. It is easy to produce warpage, bending or distortion under the action of grinding force during processing. If the workpiece is improperly clamped or under the influence of its own weight, it will also produce large deformation. In addition, under the influence of grinding heat, temperature difference and internal stress of casting, large deformation will also occur, which are unfavorable factors affecting the machining accuracy of the guide rail, and effective control and prevention measures must be taken. The machining quality of the guide rail surface is required to be high. For example, a bed rail, flat rail and straightness tolerance are 0.008 mm/1000 mm in the horizontal plane; 0.009 mm/1000 mm in the vertical plane; and the straightness tolerance of the V-shaped rail is 0.01 mm/ 750 mm; the surface roughness Ra of the surface of the rail is 0.4 μm or the like. Therefore, it is very important to correctly select the grinding method and process parameters of the guide surface. Most of the rail faces are made up of a combination of flat and beveled surfaces, so circumferential grinding or end grinding is used for grinding. In order to improve the grinding efficiency, it is also possible to use a plurality of forming grinding wheels and an auxiliary grinding head (grinding side plane) to achieve forming grinding and to use a combined forming grinding wheel to grind the rail surface at a time. Obviously, multi-grinding wheel grinding and combined forming wheel grinding have high grinding efficiency, but the structure of the grinding head is complex and suitable for mass production. It must be pointed out that when the plane of the guide rail is coarsely ground by the end grinding method, the axis of the grinding wheel can be inclined by 3° to 5° to reduce the contact area between the grinding wheel and the workpiece, and to improve the heat dissipation condition. In order to ensure the customized metal cutting disc, the diameter of the grinding wheel should not be too small, generally 1.3-1.5 times the width of the guide surface.

High-speed grinding is a high-speed grinding in which the cutting speed of the cutting disc is Vs>45 m/s compared to the conventional grinding. As early as the 1960s, Vs has been increased to 60m/s, and in the 1970s it has increased to 80m/s. However, in the following decade, due to the limitation of the rotational speed of the cutting disc at that time and the problem of burns on the workpiece, the cutting line speed No big improvement. Until the late 1980s, with the wider application of cubic boron nitride (CBN) cutting discs, and more in-depth study of the grinding mechanism, it was found that under the condition of high wear rate, along with the cutting line speed Vs When the grinding force increases, the grinding force drops sharply in a certain interval before and after Vs=100m/s. This trend will continue with the further increase of the grinding rate, and the surface temperature of the workpiece will also fall back. That is to say, after the grinding usage area that generates thermal damage, the further increase of the grinding amount not only does not exacerbate the thermal damage but causes the thermal damage to no longer to occur, thereby developing ultra-high speed grinding and high efficiency. Deep grinding laid the theoretical foundation. Ultra-high-speed grinding does not require strict limits, but grinding with a fiber cutting disc Chinese supplier linear velocity of Vs > 150 m/s is generally referred to as ultra-high speed grinding. In general, ultra-high speed grinding has the following advantages: High grinding efficiency and low cutting disc loss The higher the grinding speed, the more the number of abrasive grains participating in the cutting per unit time, the increased grinding debris, and the workpiece feed speed should be proportional to the line speed of the cutting disc of 1.13, so the ultra-high speed grinding will The grinding efficiency is greatly improved. Correspondingly, the grinding force on a single abrasive grain during ultra-high speed grinding is greatly reduced, thereby reducing the wear of the cutting disc. Many experiments have shown that when the grinding force is constant, the cutting wire speed Vs is increased from 80 m/s to 200 m/s, the grinding efficiency is increased by 2.5 times, and the life of the CBN cutting disk is also doubled. Low grinding force and high machining accuracy Due to the thinning of the grinding debris during ultra-high-speed grinding, the normal grinding force is significantly reduced with the increase of Vs under the condition of constant grinding efficiency (normal grinding force with Vs of 200 m/s only) It is 46% at 80 m/s, which reduces the deformation of the processing system. In addition, the excitation frequency of ultra-high speed grinding is much higher than the natural frequency of the processing system and does not cause resonance. The combined result is an increase in grinding accuracy. The good surface quality of the workpiece Experiments have shown that when the other conditions are constant when the line speed of the cutting disc is increased from 33 m/s to 200 m/s, the surface roughness of the grinding is reduced from Ra2.0 acid to Ra1.1 acid. Since a large amount of grinding heat will be carried away by the grinding debris during the ultra-high speed grinding process, the proportion of the incoming workpiece is small, and not only surface burn is less likely to occur, but also the depth of the surface residual stress layer becomes smaller. Several key technologies for ultra-high speed grinding The grinding process system is “grinding machine – workpiece – abrasive tool”. The key technology of natural ultra-high speed grinding is also inseparable from grinding machine, 125*1*22 EN12413 cutting disc、 grinding process and grinding fluid. Research on mechanism and process of ultra-high speed grinding At home and abroad, the research on the mechanism of ultra-high-speed grinding is not comprehensive. It is necessary to further reveal the nature of various grinding processes and grinding phenomena. At the same time, it is necessary to carry out optimization research on process parameters of different workpiece materials and grinding conditions and establish ultra-high speed accordingly. Grind the database to speed up its application. Simulating the grinding process with a computer facilitates the above research, and the virtual grinder can create a realistic grinding environment.

The use of the crusher plays a big role in the production of miners. It has high production efficiency and wear resistance. It is a meaningful equipment for SBM Cone Crusher. In order to make the equipment better, in addition to standard operation, To reduce its wear and tear, let's take a look at the factors that affect equipment loss: 1. The effect of cutter wear. When the filter used to grind the flake powder is of a suitable size, but the blade is worn, the problem caused by shredding is similar to the case of cutting a large sheet, the cut surface is wrinkled, and the edges are roughened and hooked to each other. If the bulk density of the scrap is small, the conveying performance is poor, which ultimately leads to low yield and affects the performance of the crusher. 2. The influence of the size of the filter mesh. The yield increases as the size of the screen pores increases, and the specific energy consumption of the mill decreases. In order to achieve high yields of die cut chips, a good pumping action should be formed to direct the melt through the screen holes. However, this may affect the size distribution of the flakes, which in turn affects the Portable Crusher Plant production. In addition, the large size of the sheet material makes transportation, storage, and storage bin discharge difficult. However, if the properties of the raw materials are known, better process conditions can be obtained. The flakes are large in size and low in yield, in part because of the small bulk density. Through the above introduction, it is not difficult to see that the factors affecting the loss of the crusher are mainly related to the filter hole and the wear of the cutter. Therefore, in order to improve the production efficiency, the user can reduce the loss of the equipment from these two aspects, thereby improving the efficiency.

CLEVELAND In two appearances in the American League Division Series, Andrew Miller threw 75 pitches over four innings as Terry Francona used Clevelands relief ace to get big outs rather than the finishing outs. So far, Francona has looked like a genius for his role in revolutionizing bullpen usage. But theres a risk.Miller threw 40 pitches in Game Baltimore Orioles Cool Base Black Jersey 1 against the Red Sox, and Cleveland squeaked through with a 5-4 win. After a dominant outing by Corey Kluber in Game 2 allowed Miller to rest, the left-hander returned for Game 3 and threw 35 pitches. Cleveland hung on again, completing the sweep of Boston with a 4-3 victory. Had Cleveland lost either game and that was a real risk there would have been the prospect of being without Miller in the subsequent contest.MORE: Best 50 players in the playoffsWhen we talked to our team about this (Thursday), you play every game, I think, like its your last, Francona said Friday, before Game 1 of the American League Championship Series against the Blue Jays. I really believe that. You save some bullets, thats good, too. But its not to save them because of tomorrow nece sarily. Itsmore how to win the game and how to do it Baltimore Orioles Cool Base White Jersey the best.With Kluber pitching Game 1 for Cleveland, the idea would be for him to go deep in the game anyway, leaving the bullpen mostly fresh for Game 2, before an off-day on Sunday. Where the heavy load might become an i sue is with three straight games in Toronto, where the Blue Jays are especially dangerous. Toronto had a .785 team OPS at Rogers Centre this year, 59 points higher than on the road.The failsafe is that, like with Kluber pitching Game 2 in the Boston series, Cleveland has its ace lined up for Game 5 in this series which should allow Francona more leeway in his bullpen usage for Games 3 and 4. But theres also an opportunity for the Blue Jays, if they can run up the pitch count, to gain an advantage.MORE: SN's ALCS predictionsThat would be ideal, but Andrew has been a closer Baltimore Orioles Custom White Jersey in New York, he was a setup guy, Blue Jays manager John Gibbons said. Generally those guys like that, your late-game guys, if they get ahead of you, youre in trouble. If they get one or two strikes on you, now they can go to their put-away pitch, and you basically have no chance. So, sometimes the best approach is attack them early. They may give you something to hit when theyre trying to get ahead or theyre looking for a strike. So its kind of a Catch-22. Yeah, you want to work their counts but hes still as tough as anybody out there. When he gets ahead of you, he can make it look pretty easy.That was really what made Millers pitch count soar against the Red Sox he wasnt getting ahead. Having Adam Jones Cool Base Black Jersey thrown 70.2 percentof his pitches for strikes during the regular season, including 73 percentafter joining Cleveland, Miller threw only 60 percentstrikes in the division series. It comes back to the simple truth of baseball: The pitcher starts the action, and what the pitcher does dictates so much of what is to follow.MORE: ALCS schedule, TV timesAs for the idea of the Blue Jays having an advantage against Miller because of familiarity from his time with the Yankees, that is not so much the case. Miller had six appearances against the Blue Jays in 2015, but only one this year: On April 12, Miller nailed down a 3-2 win for New York by striking out Michael Saunders, getting Ru Eddie Murray Jersey sell Martin to ground out and striking out Justin Smoak.

Year of the home run isn't ending All four runs scored in Wednesday's contest came via home run.
