  • Raymond mill is one of the commonly used equipment in the grinding industry. According to statistics, Raymond Mill has a share of more than 70% in domestic grinding equipment. However, as the production progresses, it will show a decrease in the powder rate, affecting the production efficiency. This article shares 4 reasons why the powder yield of Raymond mill is reduced and how to increase the powder yield.
    Reasons for the reduction of the powder yield of Raymond Mill
    1. The powder lock is not tightly sealed
    If the sealing of the powder locker is not in place during the grinding process of the Raymond mill, it will cause the phenomenon of powder sucking back, resulting in no powder or less powder, so check the seal of the powder locker and adjust the seal Level.
    2. The analysis machine does not work
    The analysis machine of the Raymond mill is responsible for analyzing the size of the finished powder, whether it meets the standard of the finished product, and whether it needs to be sanded again. In the case of serious wear of the analysis machine blade, it will not play the role of classification, which will cause powder production. If it is too thick or too thin, this situation can be solved by replacing it with a new blade.
    3. The fan is not adjusted well
    If the air volume of the fan of the Raymond mill is not adjusted well, the air volume is too large, it will also cause the powder output of the mill to be abnormal, the powder output will be too coarse, and the air volume is too small, the powder output will be too fine. Under abnormal circumstances, the air volume of the fan should be adjusted to correct the powder particle size.
    4. Failure of the blade
    The blade of Raymond Mill is responsible for shoveling the material. When the blade is used for a period of time or the quality is not strong enough, the wear is large, the material cannot be shoveled, and it will cause no powder or less powder. A new blade needs to be replaced in order to ensure the normal operation of the equipment.
    How to increase the powder yield and output
    Generally speaking, in order to produce a large amount of powder and a high output in the production process of Raymond Mill, there are the following requirements:
    1. Scientific and reasonable match
    When the Raymond mill is working, on the one hand, it must be considered whether the equipment model selection can meet the daily production needs to avoid equipment overload work; on the other hand, the material selection, try to choose moderate hardness, more suitable for thunder The material of the pulverizer is used to prevent the material from being too hard and it is difficult to achieve the grinding operation. It is blocked at the discharge port and causes difficulty in powder discharge.
    2. Reasonably select the speed of the host machine and improve the grinding force of the host machine
    Considering the load-bearing capacity of the host motor is a factor to improve the production efficiency of the pendulum mill. Increase the kinetic energy of the mill, adjust the belt or replace it with a new one.
    3. Regular maintenance
    After using the Raymond mill for a period of time, it should be repaired, and the wearing parts such as the grinding ring blade of the grinding roller should be repaired and replaced. The grinding bolt device should be carefully checked before and after use to see if it is loose. Phenomenon, whether the lubricating grease is enough, 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.
