Raymond Roller Mill For Getting Coarse Powder.jpg

 

Although the Raymond roller mill is mainly used to produce fine powder, in some specific areas, such as the pre-grinding process in cement production, it can also be used as a pre-mill in conjunction with equipment such as an extrusion mill to obtain a certain proportion of coarse powder products. This combined process can improve overall production efficiency and product quality.

 

Working principle of Raymond roller mill

 
The working principle of the Raymond roller mill is mainly to grind the material through the friction between the grinding roller and the grinding disc. After the material enters the grinding chamber, it is gradually crushed and refined under the extrusion and grinding of the grinding roller. However, by adjusting the pressure and speed of the grinding roller and the setting of the classifier, the degree of grinding of the material can be affected, thereby controlling the particle size distribution of the product to a certain extent.
 

How to obtain a coarse powder with Raymond roller mill

 
1. Adjust the classifier setting:
 
The classifier is a key component in the Raymond roller mill, which is used to separate the ground material according to particle size. By adjusting the speed and number of blades of the classifier, the passing rate of fine powder can be reduced, thereby increasing the output of coarse powder.
 
2. Reduce roller pressure:
 
Reducing the roller pressure on the grinding disc can slow down the material grinding speed, so that some materials are discharged from the grinding chamber before reaching the fine powder standard, thereby increasing the proportion of coarse powder.
 
3. Adjust roller speed:
 
Reducing the roller speed can also slow down the material grinding process, which is conducive to obtaining more coarse powder. However, it should be noted that the speed adjustment should be carried out under the premise of ensuring the stable operation of the equipment.
 
4. Choose the right roller and grinding disc material:
 
The material of the roller and grinding disc has a great influence on the grinding effect. Choosing materials with poor wear resistance or large surface roughness can increase the output of coarse powder to a certain extent. However, this method may affect the overall service life and grinding efficiency of the equipment.
