In many grinding mills, a classifier is used to separate the ground powder from the unground material. The settings of the classifier, such as the speed of the classifier rotor and the air flow rate, can significantly affect the particle size distribution of the final product. If the classifier is set too coarsely,

the final product may contain too many coarse particles. If it is set too finely, it may cause over - grinding and increased energy consumption. Therefore, the classifier settings need to be adjusted according to the desired product fineness.​

Maintenance and Monitoring​
 

Regular maintenance and monitoring of the grinding mill are essential for ensuring its optimal performance. This includes checking for wear and tear of the grinding media, the grinding chamber, and other components, and replacing them when necessary. Monitoring the temperature, vibration, and power consumption of the mill can also help to detect any potential problems early.
