How does a Vertical Roller Mill Work?
A: The grinding process in a vertical roller mill involves drying, grinding, and separation. The material is initially fed into the mill through the inlet chute and then transported to the grinding table. Once the material is on the table, it is ground between the rollers and the table, which generates heat and causes the moisture in the ...
