Grinding aids in dry milling - Powder and Bulk Engineering

aids. A grinding aid is typically a polar organic liquid, such as amine, glycol, or water, that’s added to a ball mill at a low level (less than 0.25 percent). This can increase the grinding rate by 20 to 100 percent compared to a system that doesn’t use a grinding aid. Many theories have been postulated to explain how grinding aids improve the

Grinding Aids for Ball Mills Industrial Efficiency ...

A ball mill generally loses its grinding efficiency remarkably at fine grinding. This is because fine particles from ground materials agglomerate and adhere to the mill liners or grinding media as coating, reducing the impulsive force of the mill. In addition, the agglomerated particles are mixed into the coarse powder in the separator and recirculated through the mill. A grinding aid prevents ...
