Raymond Mill Powder Extraction Rate

Milling rate of Grinding mill

The powder extraction rate of the raymond mill is getting lower and lower. Come and see if this is a problem. Raymond Mill is one of the most widely used equipment in the grinding industry. However, as the production progresses, there is a case where the powder extraction rate is lowered, which affects the production efficiency. Today, I will give you a summary of the reasons for the low efficiency of the flour mill.

1. The locker is not tightly sealed

If the Raymond mill is in the grinding process, the locker seal does not work, it will form a powder suction phenomenon, resulting in no powder or less powder, so check the seal of the locker, adjust the seal degree.

2. The analyzer does not work

The analyzer of Raymond Mill is responsible for analyzing the size of the finished powder, whether it meets the standard of the finished product, and does not need to be sanded again. Under the condition that the blade of the analyzer is seriously worn, it will not function as a grade, which will cause the powder to pass. Thick or too thin, in this case, you can solve by replacing a new blade.

3. The fan is not adjusted well

If the air volume of the Raymond mill fan is not adjusted well, the air volume will be too large, and the powder will be abnormal. The powder will be too thick, the air volume will be too small, the powder will be too fine, and other conditions will be checked. In case of abnormality, the air volume of the fan should be adjusted to correct the particle size.

4. The blade has failed

Raymond's blade is responsible for shoveling the material. When the blade is used for a period of time or the quality is not too strong, the wear is large, the material can not be shovel, and it will cause no powder or less powder. A new blade needs to be replaced to keep the equipment running.

Then when these faults occur, we have to find a way to solve and improve these problems. Here is how we can improve the powder extraction rate:

1. Scientific and reasonable matching

When working on the Raymond mill, on the one hand, it should consider whether the equipment model can meet the daily production requirements and avoid the overload load of the equipment; on the other hand, the material selection should be as moderate as possible, which is more suitable for mine. The material of the Mongolian grinding machine prevents the hardness of the material from being too large, it is difficult to achieve the grinding operation, and it is blocked at the discharge port, which makes it difficult to produce powder.

2. Reasonably select the host speed and improve the host grinding force

Considering the load carrying capacity of the main motor is a factor that improves the production efficiency of the pendulum mill. Increase the kinetic energy of the mill, adjust the belt or replace it.

3. Regular maintenance

After using the Raymond mill for a period of time, it should be inspected and repaired. At the same time, the wearing parts such as the grinding roller and the blade should be inspected and replaced. The grinding roller device should be carefully checked before and after use to see if there is looseness. Phenomenon, whether the lubricating grease is sufficient, and when the grinding roller device is used for more than 500 hours to replace the grinding roller, the rolling bearings in the roller sleeve must be cleaned, and the damaged parts should be replaced in time.
