The grinding part of the Raymond mill is a grinding roller and a grinding ring. In the process of processing the ore into powder, the grinding roller and the grinding ring are often in contact with the ore and the grinding is very severe. The time used varies depending on the material being processed. There are three kinds of materials used for grinding rolls and grinding rings, three kinds of manganese 13, 65 manganese, and alloy steel. The price is also very different. Some materials have relatively large wear on the grinding roller and the grinding ring, so the wear is faster. . Some materials do not wear out the equipment. At this time, the material of the alloy can be selected. Then, for those materials that are seriously worn on the grinding roller and the grinding ring, manganese 13 material can be selected. Manganese 13 material is more wear-resistant than other materials, but the price is more expensive, suitable for the grinding of materials with high hardness and high toughness.

How can Raymond mill accessories grinding rolls and grinding rings be more wear-resistant:

Raymond mill accessories have a wide range of grinding rolls, grinding rings are the most commonly used accessories, and the most easy to wear parts, the replacement frequency is very high. How can the Raymond mill accessories grinding roller and grinding ring be more durable? The grinding roller and grinding ring are made of three kinds of manganese 13, 65 manganese and high alloy. These three materials are not the higher the price, the more wearable, the material that is suitable for the material needs to be selected according to the different materials, so that it can be more wear-resistant. If the material hardness is high, you can choose the grinding roller and grinding ring of manganese 13 material. If the material hardness is low, you can choose a high-alloy alloy roller and grinding ring. Different types of grinding rolls and grinding rings are selected according to different materials, which is more durable.

Raymond mill rose relatively early in our country. At first, the grinding technology of this equipment was not advanced. Later, with the continuous improvement of market requirements, the equipment made a series of improvements. Later, the grinding technology of Raymond mill developed slowly in our country, and the production technology of Raymond mill is also improving. Now, the grinding technology of our country is also improving. The equipment has various types and functions, but Raymond mill has not been eliminated. It has been used all the time. It can be said that the equipment has witnessed the development of grinding technology in China.

Although our country's grinding technology has been greatly developed and grinding equipment has gradually increased, Raymond mill is still widely used in various industries, because Raymond mill has unique advantages, so it has been widely used. Here's an analysis of the advantages of Raymond mill:

Although Raymond mill has been produced for a long time, it still has some advanced design concepts after many technological reforms. For example, the structure of the equipment is three-dimensional, which greatly reduces the area occupied by the equipment in the production process, and the equipment has a strong system, which can be used as a unique one. The vertical production system completes the processing of raw materials, which includes the transportation of raw materials, rough processing and pulverizing process. It is more systematic and saves a lot of production processes.

In addition, the equipment is mainly used to produce fine powder, the pass-through screening rate is as high as 99%, which is incomparable with other types of grinding equipment, and the equipment has a relatively high degree of automation, using centralized control of the electrical system, basically can achieve unattended operation, this advanced production mode can save a lot of manpower and labor. Funding for mobile and engineering projects has contributed to the greater efficiency of the project.

In addition to the advantages mentioned above, the operation of the Raymond mill is particularly stable in the production process, because the important parts of the equipment are made of high-quality profiles, which ensures the firmness of the equipment, so the operation in the production process is more reliable.

The Raymond mill and the three-ring grinding mill are the common used ore grinding machines, both of which play a very important role in the powder grinding operation. Here, SBM will talk about the differences between the Raymond mill and the three-ring grinding machine.The main shaft and the rotating discs of the three-ring grinding machine are driven by the reduction box. Several grinding rollers roll and rotate, driven by the discs. The material of big block is crushed into particles by the hammer crusher and it is sent into the storage silo by the bucket elevator. Then, the crushed one is sent at the middle of the rotating disc evenly by the electric-magnetic vibrating feeder. The material scatters by the centrifugal force and falls into the roller path of the grinding ring to be ground by it.When the material like ore has been crushed by the first layer of the disc of the three-ring grinding machine and it will fall into the second layer and the third one. The air outside is drawn into the machine by the blower and it will take the coarse powder, ground by the third layer disc, to the powder separator, which makes the coarse particles go back to be ground again and makes the fine ones into the cyclone collector, which will be discharged from the discharge valve, which is just the final product. However, the air flow with little dust will be discharged by the dust collector.The working principle of the three-ring grinding machine is the same as that of the Milling Machine, which is that the grinding rollers rotate around the grinding ring and the grinding roller rotates on its own axis. At the bottom of the grinding roller is the shovel blade device. At the rotation of the shovel blade and the grinding rollers, the material is being fed into the gap between the grinding roller and the grinding ring by the shovel blade to form a layer of material, which is ground by the rotating grinding rollers. However, the material should be ground at three layers in turn inside the three-ring grinding machine.

Raymond mill and other ore grinding processing machinery and equipment, in the process of grinding ore and other materials, there will be problems such as dust leakage, Shanghai SBM mining machinery here to talk about the environmental protection of the ore mill, environmental protection dolomite mill is a hot spot for customers' current powder investment. More and more customers have abandoned the pursuit of low prices and began to turn their attention to the energy saving and environmental protection of Raymond Mill.

In the past two years, the state has always attached great importance to environmental protection issues, and the supervision and inspection of production-oriented enterprises is very strict. During this period, there were also many Raymond mill production lines that did not meet the requirements, so they were suspended for rectification. Everyone knows that in the industrial milling industry, it is very easy to cause dust pollution to the environment, so the environmentally friendly Raymond mill came into being.

Raymond mill is a kind of ultra-fine grinding equipment for processing ore. The working principle of the machine is that the grinding roller rotates the crushed grinding material under the action of centrifugal force at high speed, and then passes through the analysis machine and the fan. Wind selection achieves fineness and yield, and control fineness is controlled by wind selection and analyzer speed. Raymond mill is suitable for processing material fineness range between 50-400 mesh, one feeding once into powder, non-stop feeding non-stop discharging.

The most important thing for the production and fineness of the grinding mill types is the use of wind. What kind of wind is the Raymond mill? The Raymond mill uses a positive and negative pressure device with a blower and a suction part. The use of wind is very efficient, so we must pay attention to the use of wind. If the wind is not used well, it will have an impact on the output and fineness of the equipment. Raymond mill has a professional dust collector in the production process, which is also very environmentally friendly and energy-saving.

With the increasing number of Raymond machine manufacturers, the price of 4r Raymond mills in the market is also different. The price of raymond mill in the same region and different regions is different. The price of different models is not needed. said. For the choice of Raymond mill price, buyers need to compare the price and cost performance of each place, and finally find a supplier that meets their own needs.

Industrial grinding equipment was first built in Berlin and is mainly used for coal-fired power plants. This role has been retained until now, and large-scale thermal power plants use modern coal-grinding equipment 4r Raymond mill, which has just been manufactured. The industrial grinding equipment is not called Raymond mill. Later, through some improvements, the first generation Raymond mill system was created. The structure is to erect a rotating spindle with plum blossom frame in the center of the machine. Three or more rotating grinding rollers are suspended on the rotating shaft, and the rotating shaft rotates at a certain speed to drive the grinding roller to swing outward, and is driven by centrifugal force to the grinding ring embedded on the inner wall of the cylinder. Although this system has changed, most of the work has not changed.

Raymond Mill has grown from one country to the country, from the use of an industry to the use of many industries, from the grinding of a material to the processing of hundreds of materials, in the process also produced a lot of thunder The mutual exchange between the country and the country of the Mongolian machine factory, the production enterprise and the production enterprise promoted the development and transformation of the equipment.

Raymond mill's conventional installation method consists of a main engine, a fan, a cyclone, a dust collector, and a piping system. Nowadays, a kind of installation method is more and more popular with users. That is, raymond mill uses fan power to directly transport the powder into the powder tank, no longer uses the cyclone separator, or only uses a part of the cyclone separator. The advantage of this method is that the powder after the Raymond mill grinding can be directly into the tank, which reduces the transportation and packaging of the powder, greatly saves the labor cost and saves the powder transportation cost. And this method is common on the size of the Raymond mill model, but it is different. The main difference is: due to the different sizes of Raymond mills, the height of the Raymond mill to the top of the tank has been limited. Restriction, the larger the Raymond mill, the larger the matching tank and the larger the storage volume. As for the height of each model can be matched, depending on the experience of Raymond mill manufacturers, do not blindly increase the tank, sometimes it may not achieve the expected results, but the investment tank will not cause The necessary loss. Therefore, although some methods are easy to use, they still need to refer to precedents. Welcome new and old customers to consult.

The raymond mill is deformed, generally due to heat, and the conversion of the thermal unit to the structural unit: for a highly nonlinear coupling problem, because it can get the best solution. When the coupling problem is not highly nonlinear, the indirect coupling method should be used because the indirect coupling method is more flexible and efficient, and the two analyses can be independent. In the study of thermal deformation, the thermal-structure-coupling coupling method was used for research. The indirect method performs the basic steps of Raymond's thermal stress analysis: converting the unit type and converting the thermal unit into the corresponding structural unit. The analysis process is identical to the steady state and transient thermal analysis processes.

Thermal Deformation Analysis of the Raymond Mill Spindle System: The indirect rule refers to the thermal analysis first, and then the obtained joint temperature is added to the structure as the body load to solve the stress distribution and thermal deformation of the structure. In the whole process of connection analysis, there are conversion problems of thermal unit and structural unit, and the corresponding relationship between thermal unit and corresponding structural unit. Analysis of Raymond's thermal deformation is actually an analysis of the thermal stress problem, that is, the interaction between the two physical fields of heat and stress, which is a coupled field analysis problem. There are generally two methods of analysis of Raymond mills: direct and indirect.

The direct method refers to the direct use of coupling units with degrees of freedom of temperature and displacement, while obtaining the results of thermal analysis and structural stress analysis. The thermal stress analysis by the direct method mainly uses a coupling unit, which includes a thermal stress coupling unit and a heat-stress-electric coupling unit. Therefore, always pay attention to the problem of Raymond mill deformation.

Raymond Mill's production bottlenecks are mainly in which part?

First of all, we need to understand the production process of Raymond Mill: grinding process and winnowing process.

The production bottleneck of the grinding process is mainly the blade angle problem, the sealing problem of the roller assembly, and the wearing degree of the wearing parts.

First of all, the angle of Raymond's blade has played a vital role, and some Raymond Mill manufacturers are apt to ignore this problem. Raymond's blade lift position is high and low, making the blade shovel The starting material cannot be accurately delivered to the grinding position, which greatly affects the production of Raymond Mill.

Secondly, the sealing problem of the roller assembly, which is directly related to the use of Raymond Mill manufacturers can normally use the problem of normal production. If Raymond Grinding Roller Assembly cannot effectively seal, then the inside of the assembly is very easy to enter into powder. After the powder is poured in, the total achievement of Raymond Mill is easy to be broken, and often it will be broken, which will bring about normal production. Serious trouble. The latest assembly developed by SBM Machinery adopts the principle similar to the mechanical seal, adopts multiple oil seals and progressive zero-gap sealing, and the effect is unanimously recognized by the society.

The last is the degree of wear of the wearing parts. If the wearing parts (ie grinding rollers and grinding rings) are made of ordinary carbon steel, then they will wear off quickly, which will increase the production cost of Raymond Mill manufacturers. The maintenance rate will also increase. It is recommended that customers use high-manganese steel Raymond mill rolls and grinding rings.

Industrial milling can not be separated from the deep processing of Raymond Mill, especially in some fine powder processing areas. The following SBM Raymond Machine Factory summarizes some common sense and hopes to help everyone. In the case of higher moisture, in the ultra-fine grinding production line, the dryer is connected by using a screw conveyor, and there is a special material that needs to be added to a special device for mechanical production.

In Raymond Mill operation should pay attention to the following aspects: Raymond Mill raw material concentration should be appropriate, the actual operation should pay attention to the adjustment of water, in the country for the mine industry, Raymond Mill industry will High-speed growth trend appears; when closed-circuit grinding, proper cyclic load should be provided. In a certain range, the Raymond Mill's productivity increases with the increase of the sand return ratio. Under the condition of a large return to sand ratio, the fluctuation of the classification efficiency has little effect on the mill productivity. Therefore, it is beneficial to increase the sand return ratio properly. Usually, the amount of sand returned by a rod mill is smaller than that of a ball mill because of the small gap in the volume of the medium of the rod mill.

Raymond Mill speed should be controlled properly. At slightly higher speeds, higher productivity can be achieved. However, because the relative motion is intensified and the grinding medium has a large amount of energy, it is easy to make the material crushed. Ultra-fine grinding involves a wide range of industries, and the frequency of use in various industries is also very high, such as mining machinery industry, chemical metallurgy industry and industrial milling industry.
