With the wide application of sand aggregate, the sand production is used in more industries gradually. Our sand making machine is gaining a huger market.In the recent years, many sand producers adopt an expansion-oriented competition mode, which often pay too much attention to market share instead of keeping customers. It is shown mainly in ignoring service and emphasizing selling. River sand has many advantages in construction, but with the rising quality requirement of building and different forming conditions, the river sand often has different features. This is harmful to the quality stability of concrete, especially high-performance concrete. The main factors to evaluate the products quality are their grain shape and size.

Production situation of domestic downstream processing enterprises is not very good, just as the current iron and steel industry, which makes its market demands decrease. The sand in construction industry and argil in light industry need to be washed and purified. The washability of ores means the difficulty level to separate slurry from ores. Its washability is mainly related to the nature, content and existing state of clay in ores. The machine rotor adopts center structure, and the spiral blades are installed on the central axis. The sand making machine is a mechanical classifying machine whose principle is that the specific gravity of different materials has different falling speed in liquid. Sand production line can process cobble, pebbles, granite and other mining stone into the ideal artificial sandstone, reducing transportation cost.

With the entering of foreign capital in the recent years, the international mining equipment competition is more and more fierce. If we want to have a position in the market, we should improve the quality and technical content of products and narrow the gap between us and advanced countriesThe biggest problem of sand production line is large energy consumption. Now people have a higher requirement of its energy saving feature.

It's well know that China as a great power of mineral resources has abundant mineral reserve, which is also a place that has rich coal, phosphorus, aluminum and other mineral resources. At the early stage, deep processing ability of mineral resources is weak, so, it's very necessary to pay attention to exploitation of raw materials. But in new period, people's lay more emphasis on efficiency of mineral resources exploitation. SBM as professional manufacturer of mining equipment has rich experience in crushing of mineral ores. The high-performance hydraulic cone crusher as one of the most commonly used crushing equipment accelerates development of mineral resources.

In next few years, the demand for mineral crushing equipment will increase greatly. However, at the same time, there are higher requirements on crushing equipment, such as efficiency, performance, environmental protection characteristic and so on. Traditional cone crusher with low efficiency and poor flexibility cannot satisfy crushing demand of coal, rock and other mineral resources. While new type of hydraulic cone crusher with stable performance, high crushing efficiency, flexibility, environmental protection and energy conservation plays an important role in exploitation and deep processing of mineral resources.

Hydraulic cone crusher can promote exploitation of mineral resources in China, which plays a significant role in mining machinery industry, which is well received by various customers by relying one superior quality and excellent performance. Precisely because of high crushing ratio, hydraulic cone crusher has become pillar crushing equipment of heavy industry. Faced with a new round of industrial demand, cone crusher continuously innovate in economic development. Hydraulic cone crusher is new type of cone crusher, which has multifunction in many industries. When crushing hard materials, hydraulic cone crusher is of high efficiency and low production cost, which has good particle shape and ensures quality of sand aggregate. Hydraulic cone crusher not only increases the capacity of cone crusher, but also increases the economic benefits. Hence, hydraulic cone crusher can completely satisfy the demand of large construction projects.

The production of ultrafine mill is related to many factors. In production, if we find that the output has changed, we must find the causes in time and solve them. Among the many factors that affect the output, One of them is the nature of the feed, and the feed properties include hardness, viscosity and other aspects. What is analyzed here is whether the moisture of the feed has an effect on the yield.

Through the introduction of the working principle of the ultrafine mill, it can be found that when the machine processes materials, the blade first shovels the stone between the grinding rollers, and then, under the action of the strong centrifugal force and gravity of the grinding rollers The stone is tightly crushed on the grinding ring, so that the material is gradually crushed and ground into powder. In this process, a lot of heat will be generated in the grinding cavity. At this time, if the moisture content in the material is large, the moisture will be heated. There will be a certain degree of evaporation, so it will affect the direction of air flow in the grinding chamber, not only affect the size of the output, but also cause a blast accident in severe cases. This is very important for the production of ultrafine mills. The disadvantage is that it is very important to control the moisture in the feed.

In addition, during work, if the moisture content in the feed is relatively large, when it is ground, the powder will adhere to the grinding chamber because of the high humidity, which will easily cause the production of blocking phenomenon, and it will face the adhesion. More and more powders will cause the speed and pressure of the ultrafine mill to change, which will reduce the output. Such larger moisture stones will also cause increased wear of the accessories inside the mill, affecting the machine.

The article mainly introduces the impact of stone moisture on the output of ultrafine mill. The above analysis of this problem is more detailed. If the moisture content in the feed is large, the impact on the output is mainly two aspects, one is through The impact of the direction of the air flow in the grinding chamber changes the output. Second, the powder with high humidity easily adheres to the grinding chamber, which affects the speed and pressure, and then reduces the output. Therefore, in order to ensure the output of the ultrafine mill, Need to ensure the reasonableness of moisture in the feed.

The superfine pulverizer's spreading pan is used to receive the material falling from above and disperse the material to the periphery by its own rotation. The spreading pan is very important for the uniform looseness of the spreading material, which affects the efficiency of powder selection of the mill. What is the reason for the failure of the superfine mill's spray pan in use?

In the use of the ultrafine mill, we have concluded that the main reasons for the failure of the spreader tray are as follows:

1. The uneven feeding causes the feed tray to fail. If the upper part of the feed inlet is not uniformly fed, it will affect the position and thickness of the material falling on the spreading pan, and even cause the rotor of the spreading disc to shift. It cannot be evenly spread around, causing the lack of the material curtain in some places. , Affecting efficiency and product quality.

2. The rotor speed of the mill is not suitable. Because the spreading disc is coaxial with the analyzer rotor, the speed of the ultrafine mill analyzer will affect the spreading disc to some extent, but in general, the speed adjustment of the powder selecting machine is based on the user's product details. Requirements and actual operating conditions, will not consider the actual spreading situation of the spreading pan. When the rotation speed of the rotor is too small, it will cause the material disc to not fully disperse the material, or single-sided material concentration; when the rotor speed is too large, the powder will be over-spattered, which will cause the powder to impact the cylinder wall and form a dense material group. And large gaps are also not conducive to uniform spreading.

The above is a summary of the reasons for the failure of the superfine mill's spraying tray, summarized in the experience of Shibang machine technicians. I hope it can be helpful to everyone.

In addition, I also want to remind everyone that the role of the disc of the superfine mill is not only for spreading, but also for pre-grading. The spreading pan can spread the coarse powder under the effect of its own gravity during the spreading process. This is because the air flow is not enough to promote the larger size and gravity of the material, so it can achieve the pre-classification of the material. In addition, because the spreading disc is a rotary motion, under the action of centrifugal force, the centrifugal force of the coarse material is also large, resulting in a large centrifugal speed, so when the spreading disc reaches a certain rotational speed, the coarse powder hits the surrounding shell Physically, this can also achieve the purpose of pre-grading.

During the production process of the ultrafine mill, the air passage is blocked, which affects the production process. If it is not handled properly, it will also cause damage to the machine. No matter what kind of situation, it will affect the customer's profit problem. Therefore, it is necessary to find the cause of the air duct clogging in time and then take a reasonable solution. Here are the reasons for the air duct clogging in the production process of the ultrafine mill machine. How can we solve these problems?

Many people have different opinions about the cause of the air duct blockage. Of course, the solutions adopted are different. In order to better solve this problem, the experts of Shibang opened the specific cause of the air duct blockage phenomenon of the ultrafine mill:

The point is that during the production process, the feeder does not match the production efficiency of the equipment when the material is added to the ultrafine mill. The excessive material is added and the ultrafine powder production equipment does not process these materials in time. This leads to the clogging of the air duct. To solve this problem, it is necessary to adjust the feeding speed so that it matches the production speed of the ultrafine mill;

The second point is that the humidity of the material processed by the ultra-fine milling machine is too high, which causes the fine powder to adhere to the air duct, which will cause clogging in the long term. Therefore, pay attention to the screening of the material during production or dry it before putting it into the material.

The third point is that during the production of the ultrafine mill, due to the sudden power failure or shutdown, the fan of the ultrafine mill did not run normally when the ultrafine mill was started, which caused the air duct to be blocked. To solve this problem, it is necessary to start the equipment first. Observe whether the fan can run normally and then put the materials into production.

There are several reasons for the blockage of the fan of the ultrafine pulverizer introduced above, and solutions are given for each cause. In the actual production line, the causes can be eliminated one by one according to the faults of the ultrafine pulverizer and then resolved to help The equipment works more smoothly.

During the production of ultrafine grinding mill, its performance in all aspects will be affected by various factors, which will lead to the decline of the output of the equipment. One of the factors is the difficulty of material feeding, which makes it difficult for the ultra-fine grinding machine to receive continuous and uniform feeding, and its production process will be inevitably affected. In order to solve this problem, we must find out the reasons for the difficulty of feeding. The following is the problem of ultra-fine grinding The pulverizer Manufacturer & mdash; & mdash; Shibang machine will analyze for us what causes the feeding difficulty in the production of ultrafine pulverizer.

Like other types of grinding equipment, the ultra-fine grinding machine also has certain requirements for the feeding, and because the equipment is used to produce ultra-fine powder, the requirements for the feeding are more stringent, so when the feeding does not meet the requirements, it will cause the problem of difficult feeding. The feeding does not meet the requirements are mainly the following situations: the feeding speed is too fast, the material moisture content is too large As well as the blockage of discharge pipe, only these problems can be solved to solve the problem of difficult feeding.

In order to solve these problems, we should first operate according to the factory instructions, control the feeding speed, and feed according to the requirements of the equipment for material humidity. We should not put materials with too much water content into the equipment for ultrafine powder production. In addition, we should check the discharge pipe regularly. If any foreign matter is found to be blocked, we should clean it in time to ensure the smoothness of the discharge pipe, so as to ensure the ultrafine grinding machine Production goes well. The above summarizes several reasons that lead to the feeding difficulty in the production of ultra-fine grinding machine, and gives the solution, mainly according to the instructions to carry out appropriate operation and ensure that the feeding meets the requirements and the discharge pipe is smooth, which can solve the problem of difficult feeding, and then solve the problem of the impact on the equipment output.

Grinding Mill, widely used in the high fine powder generation and processing mining, metallurgy, chemicals, building materials etc., can be used including more than 280 kinds of materials. As one of the most widely used mining equipment, it is higher in investment and short lifespan. For frequent replacement of parts and various manufactures on the market, so clients are troublesome for ultrafine grinding mill. Now Staff of SBM has a few tips for that:

First, considering the feed size and particle size. Selecting the appropriate grinding mill by particle size. There are many classifications of grinding mill, after crushed by crushers (coarse, intermediate and fine crushing), the particle size between 8-20mm, to get the desired fineness of products, the grinding mill is necessary;

Second, European grinding mill is widely used. the main components consists of rotating cylinder, which contained with material crushed. Raymond mill, simple structure, reliable performance, simplified maintenance process, long working hours, strong adaptability of materials, high crushing ratio and large production capacity, meet the needs of modern large-scale industrial production;

Thirdly, when selecting grinding machine, we should consider such as: physical properties of the material, finished products, preparation, working environment, energy consumption, working efficiency and infrastructure investment. We should make decision by contrast and comparison.

The raymond mill equipment mainly processes ore, so the internal parts of the equipment are prone to damage after working for a period of time. For example, the cutter disc, knife holder, rotor and other components are easily damaged in the raymond mill. Damaged parts, these devices have direct contact with materials, so there will be problems of looseness or noise during long-term work. At this time, maintenance is required. Maintenance is not only labor-intensive, but also wastes material and money. At this time, someone will ask about the equipment. Is the maintenance necessary?

Every part of the raymond mill equipment is new when it leaves the factory, so the working state of the equipment is better after the break-in period, and the production benefits brought to the project are also better, but parts will be encountered later The problem of damage. Although the equipment cannot work normally due to the damage of the components, the entire equipment is not scrapped, and only the damaged components need to be repaired to make the equipment work normally.

The capital required to replace a piece of equipment is far greater than the funds required to replace the components of the equipment. The replacement of the components has extended the service life of the equipment compared to the replacement of the equipment. The equipment can also serve the milling project. The benefits brought to the production project are relatively large compared to the replacement equipment, so it is necessary to repair the ultrafine mill equipment after using it for a period of time.

When performing maintenance on the raymond mill, pay attention to follow the correct operating steps, and during the daily work, the equipment should be reasonably lubricated and comprehensively inspected. Once problems are found, they should be dealt with in a timely manner to avoid causing more damage to the equipment production. Great influence.

Recent years, the producting technology of sand making machine has not been the industrial secret, but it is the first time to apply solar energy in sand maker. As we all know, the sand making machine is always exposured in the sunshine for the whole day, so it's not impossible to use the solar energy to charge its generator.

Solar Energy, usually refers to the sun radiation Energy, in the modern society, generally used for power generation. Since the earth created creatures, those creatures depended on the heat and light of the sun, band also human beings knew to dry the objects in the sunlight, by which they kept food, such as salt-making and drying of salted fish, etc. But with the reduction of fossil fuel resources, then people are disposed to develop solar energy further. The methods of solar energy using include passive use (solar-thermal conversion) and photoelectric conversion . Solar power is a new kind of renewable energy. In the broadest sense, the solar energy is the resource of much earth energy, such as wind power, chemical energy, water potential energy and so on.

Solar energy comes from the earth's outer universal bodies (mainly solar), most of the energy human need is directly or indirectly, from the sun. Rightly all kinds of plants, through photosynthesis, convert solar energy into chemical energy, storing the energy in plants body. Coal, oil, natural gas and other fossil fuel ware formed from the buried plants and animals under the ground after a long geological generation. These are, in essence, the fixed solar energy of those ancient creatures . In addition, hydropower, wind energy, are also transferred from the solar energy. The solar power system, the earth itself, reserves of energy which usually refers to the energy related with the interior earth heat energy and that relevant nuclear core source energy.

And what is related with the nuclear reactions is nuclear power. When the structure of the nucleus changes, it will release a large amount of energy, called atom nuclear power, hereinafter referred to nuclear energy, commonly known as the atoms power. It originated from the nuclear fission resource from the uranium and plutonium in the procedure of nuclear fission reaction , including the fission can resources of the tritium lithium deuterium stored in the sea. These substances release energy during nuclear reactions . At present the biggest use of nuclear energy is generating electricity. In addition, it can be used for other types of power supply, the heat source, etc.

Through the introduction, we know that the sand maker applies solar power to generating electricity, so as to achieve self-sufficiency, which is completely feasible. If you are interested in our product, call our customer service number for detailed questions.
