The emergence of Raymond Mill as a milling machine conforms to the development of the times! Raymond mill is indispensable for the beneficiation equipment line! Raymond mill is the most widely used mill equipment after construction, chemical, mineral processing, etc. after the crusher! However, now the overall development history of Raymond Mill is ordinary and ordinary! Who knows that the emergence of Raymond Mill almost set off as much as an industrial revolution! The production technology level of Raymond mill equipment and crushing equipment is gradually mature! At present, our common Raymond mills are 3R, 4R, 5R, 6R, which is one of the most common series of mills! In the development history of the mining industry, Raymond Mill has played a role and contribution that cannot be ignored in the processing and grinding of metal ores and non-metal ores. The development status of non-metallic miners is one of the important indicators to measure a country's scientific and technological progress and industrial development. The output value of non-metallic mineral powder in many industrial developed countries has exceeded that of metal mines. SBM heavy industry mill can be used to process non-metallic mineral materials with hardness below six grades. After years of development, it has become the mainstream equipment for non-metallic ore processing. The Raymond mill, ultra-fine powder mill, high-pressure suspended roller mill, high-pressure micro-powder mill, etc. produced by milling machine manufacturer SBM Heavy Industries, are self-developed, technically innovative The industrial milling equipment produced is highly efficient and low in energy consumption. In order to meet the requirements of users for processing different rocks, fineness, output, uses and different process requirements, in line with local conditions, optimize the investment scale, with the purpose of obtaining the best economic benefits for investment, the industrial mill production project , SBM Heavy Industry Machinery Co., Ltd. dispatches engineering and technical personnel to the user site for on-site survey, planning, design process, and is responsible for later installation and commissioning and maintenance services.

The working principle of Raymond mill is that the grinding roller crushes the grinding ring, and the crushing effect is achieved by the combined action of the analysis machine and the fan, and the material is powdered once, and the fineness is adjusted conveniently. The Raymond mill is installed in a complete set. It is a sealed device. The design of the circulating air is that there is no air leakage in its pipe connection. The sealing requirements are very strict. Where there is a leak in the connection of the pipeline, the output will be affected, the equipment is prone to tremor, and the output will be reduced. And there is a more critical place of Raymond Mill, that is, the position of the discharge port, which must be tightly sealed and cannot leak air. This place sucks in the air. If the air leaks, the material will not come down and return to the working chamber of the host. Inside, this can easily cause blockage of the device. The operation of the Raymond mill should be maintained and operated by professional technicians. Before going to work every day, the equipment should be inspected. The several roller assemblies of the Raymond mill need to be refueled once a day. During the refueling process, the continuous inspection of the grinding roller Whether and the grinding ring need to be replaced, and whether there is a phenomenon of bearing damage. Regularly check whether the equipment screws are loose, check whether the dust bag of the device is breathable, and pat it once a day to keep the dust bag breathable. When the Raymond mill is cutting, the feeding must be uniform, and there can be no too much or too little cutting. Too much cutting can easily cause blockage of the equipment. Too little cutting will cause too much equipment noise.

There is a certain difference between the design speed and actual use speed of the Raymond mill. The rotation speed of the small Raymond mill is about 280-220 rpm, the rotation speed of the medium-sized Raymond mill is about 140-180 rpm, and the rotation speed of the large Raymond mill is about 60-120 rpm. The rotation speed of the Raymond mill is directly related to the output and performance of the Raymond mill. The grinding capacity indicators of the Raymond mill mainly have three items: the rotation speed of the central axis of the Raymond mill, the quality of the Raymond grinding roller, and the centrifugal radius of the Raymond grinding roller. The rotation speed of the central shaft is directly related to the use efficiency of the Raymond mill. The same Raymond mill may have different output due to the rotation speed of the central shaft of the Raymond mill. In the process of using the Raymond mill, some customers install their own inverters to easily control the spindle speed of the Raymond mill. Grinding light materials (or small materials) can reduce the speed of the Raymond mill because of this The grinding capacity of Raymond Mill is sufficient, and the reduction of speed is to save power consumption and noise of the machine. If it is heavy material (or massive hard material), it is necessary to increase the rotation speed of the central axis of the Raymond mill, thereby increasing the centrifugal force, increasing the grinding capacity, and increasing the output rate of the Raymond mill.

Slag is the residue after beneficiation or smelting. A few years ago, most of the slag produced was discarded or buried, and it was not effectively used, which wasted a lot of resources and polluted the natural environment. In recent years, the particle size of environmental protection has been continuously enhanced. With the advancement of technology, people have a better understanding of slag. We found that slag is an active mixed material of cement after grinding, so the slag in the industry has been integrated in the past two years The utilization rate has been improved, as the main production equipment vertical roller mill in slag processing, has been developed. There are many types of mills on the market, which mills are suitable for processing slag? Investors who invest in the slag processing industry will definitely encounter this problem in the initial stage. Due to the high hardness of slag, it is recommended to use SBM-S slag Mill to process it. SBM-S slag vertical roller mill is our company based on many years of vertical roller mill R & D and production experience, for the special product of granulated blast furnace slag, through the multi-unit cooperation of the professional team dedicated research, the vertical roller mill thermal system calculation, equipment selection calculation , The main parameter calculation, the powder separator calculation and research and development and design of ultra-fine grinding equipment, which integrates grinding, drying, classification in one, has the characteristics of high grinding efficiency, strong drying capacity and so on. The process is simplified, the area is small, the investment is saved, the power consumption is greatly reduced, the service life is long, and the ultra-fine grinding innovative process technology with high operation rate is realized.

Raymond milling machine is an ultra-fine milling equipment for processing ore milling. The fineness adjustment range is between 50-400 mesh, and it can be fed into powder once. Raymond mill uses limestone and other ore for processing limestone and other ore, energy saving and environmental protection, small footprint, low energy consumption, simple and efficient. The main components in the Raymond mill are grinding rollers, grinding rings, air ducts, blades, plum blossom frames, main shafts, etc. There are cast iron parts and cast steel parts. Raymond Mill's grinding rollers and rings are mostly made of alloy steel, which is more wear-resistant. Today, I will briefly introduce the method of adjusting the fineness of the processed materials of the Raymond milling machine that many friends have consulted. The fineness adjustment of the Raymond mill is simple as long as the damper is used to control the air volume. Another point is to adjust the fineness of the analyzer by controlling the speed of the analyzer. The fineness adjustment of the Raymond mill is that the air volume is large, the fineness is coarse, and the output is high; the air volume is small, the fineness is fine, and the output is low. Raymond mill adopts the principle of rolling roller air separation, so the wear of the grinding roller and grinding ring is relatively strong. When processing the material, it is recommended to crush the material below 3-5CM, so that the grinding roller and grinding ring Less wear and tear and higher processing output. Raymond mill is designed with positive and negative pressure. In operation, it is necessary to clarify the working principle and understand which part is positive pressure and which part is negative pressure. Another key technology of Raymond Mill is the valve at the discharge port. When there is no material, it must not leak. When there is material, it can play a sealing role. At this time, the material can be discharged at a uniform speed, but also Don't put too much material, there must be a small amount of material stored to play a sealing role, so the output is relatively high.

Due to the special use environment, Raymond mill must be properly treated before and during use. In the selection of materials in the design stage of Raymond mill, the media environment should be considered, and the materials must have good adaptability, corrosion resistance and thermal insulation. In the design of the Raymond mill structure, the welding seam should be minimized to prevent corrosion after penetration. At the production stage of Raymond Mill, we must also pay attention to anti-corrosion work. The mechanical materials should be inspected and registered. We must pay full attention to the anti-corrosion work of Raymond Mill, especially to strictly control the design specifications and design quality. When the Raymond mill is damaged, by repairing or replacing the parts, the Raymond mill can be guaranteed to work normally, that is, under low-cost maintenance, economic efficiency is improved. Then, the necessary maintenance work on the Raymond mill can keep it in good operating condition and prolong the service life of the Raymond mill.

Sand making machine is the most important equipment in the sand and gravel production line, and also the equipment with the most serious loss, usually including plate hammer, counter lining, casing lining and rotor body guard plate. Among them, the failure time of the hammer is the shortest, and the repair cost is quite high. Therefore, the most important thing to solve the high-efficiency wear is to reduce the loss of the hammer. So what exactly causes the Sand Making Machine parts to wear easily? First, the influence of processing capacity and discharge gap. The processing capacity of the sand making machine has a certain influence on the loss of the hammer. When the processing capacity increases, the particle size of the product will become coarse, the crushing ratio will decrease, and the unit wear rate of the hammer will also increase. Changing the size of the discharge gap can also change the thickness of the product size to a certain extent, so it also has a certain impact on the wear of the hammer. Second, the impact of the nature of the material to be crushed. The material to be crushed also has multiple effects on the abrasion of the hammer, including factors such as the hardness of the material, the size of the feed particle size and the moisture content of the material. They all have different effects on the abrasion of the hammer to varying degrees. Hardness has the greatest influence on the abrasion of the hammer. Third, the effect of line speed. The size of the linear velocity directly affects the size of the impact force exerted by the hammer on the material and the size of the crushing ratio, and plays a decisive role in the particle size of the product. After understanding the reasons for the serious loss of the hammers of the sand making machine, the next thing we need to do is to "apply the medicines to the symptoms". For the specific problems of the sand making machine, we often communicate with the users and find the reasons to solve the problems in time. Of course, it is best if we can prevent it from happening. Aiming at the problem of the abrasion of the hammer in the sand making machine, SBM Heavy Industries provides everyone with the following countermeasures: reasonable selection of working parameters and structure; improving the utilization rate of the hammer, reducing the replacement time of the hammer; improving the material of the hammer to make it not only have the Strong abrasion resistance, but also has a high turbidity resistance. The service life of sand making machine parts directly affects the production efficiency of sand making. Unreasonable use of equipment can only increase the production cost of the enterprise and reduce production profits. Therefore, SBM Heavy Industry recommends that new and old customers should use scientifically when using equipment At the same time, it must be maintained in time to minimize the wear of equipment parts and effectively extend the service life of the equipment. How to complete the whole set of sand making machine equipment for effective application. Sand making equipment is an assembly line composed of many equipments. Based on feeding equipment, first-level crushing equipment, fine crushing equipment, and screening equipment, some need washing equipment flow. The complete sand making machine includes: It can be repaired and designed by itself according to the drawings provided by the manufacturer of the site without the need to purchase. Secondly, the vibrating feeder's function is to feed uniformly to the next process to ensure that it does not block or jam during the crushing process. Next is the first-level crushing equipment, usually choose jaw crusher (E-break) to do a crush, its structure is hard, it is very reliable and durable for crushing stones, through the jaw crusher The crushing cavity squeezes the stone inside, and then evenly crushes the material into materials that meet the feed standard of the next layer of sand making machine or fine crusher equipment. The next process equipment of the jaw crusher is the high-efficiency sand maker or fine crusher. As the name implies, the sand maker is to make the material into a finished product with the same fineness as the sand. The finished product is not directly used after it comes out, and it still needs to be behind it. Equipped with a vibrating screen (vibration screening machine), the finished sand is screened evenly, and sand with similar particle size and fineness is separated according to type, thus ensuring the standardity and uniformity of the sand. Some places are mountain sand, which contains mud, or river pebbles, etc., then we may need to use a sand washing machine to clean the sand to meet the national standard. The equipment generally included in the complete sand making machine production line is basically mentioned above. In some places, depending on the output and the texture of the material, our supporting process equipment may also be different. If you need it, Shanghai SBM Heavy Trade Union will provide you with the most professional production line configuration solutions and equipment. If you have any questions about the sand making machine equipment, you can consult us at any time, and we will serve you wholeheartedly.
