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 ...

The working principle of vertical roller mills is relatively simple. In a rotating drum, grinding media (steel balls or ceramic beads) are fed through the mill's inlet, and the particles are ground into smaller sizes by the mechanical forces generated by the motion of the drum. The ground material is then passed through a classifier, which ...
