Grinding aids in dry milling - Powder and Bulk Engineering

during grinding is by using grinding 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 ...
