Glo Progress With Grinding Aids For Vertical Roller Mills
Aid into the mill close to the rollers. each grinding aid was added until constant mill parameters were achieved, within a maximum of 20min. to clean the mill from remaining grinding aid, the mill was run blank in between. it took up to 90mins to come back to the base line. the chemical structure of the added grinding aids was previously.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.
