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.

When raymond mill is in use, the sound is relatively large before the material is fed. When the grinding roller rotates in the grinding chamber, it will emit a loud sound of metal rolling noise. This is a normal category, when the material enters the grinding chamber. The sound will become smaller. This is because the roller is rolling the material. Because there is padding under the roller, the sound is not so big. During the rolling process, the blade throws up the material, and then The grinding roller is used for grinding and grinding, so as to achieve the powder, the finished powder will be blown by the blower, analyzed by the analyzer, then enter the pipeline, and finally fall into the powder collector.

When raymond mill main machine shakes badly, it is necessary to stop the inspection, first check whether the materials are piled up, not row out, and the vibration caused by it. Then check Raymond machine's grinding roller and grinding ring, is it deformed or lost? If it is, it will also cause large vibrations and noises. If it is, it will replace the grinding roller or grinding ring, and it can eliminate the failure; another reason will also cause a big shock, that is, the loosening of the anchor bolts and the anchor bolts. Raymond machines cannot be well fixed. When the material enters, the rotation of the motor will cause the main engine to sway, resulting in a large vibration failure. In this case, the machine should be shut down immediately and the anchor bolts must be tightened.

Raymond Mill's operability is very important, should be carried out in strict accordance with the operating manual, failure, immediate maintenance, may not be forced to start with a faulty Raymond Mill work, so as not to cause greater losses.
