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 ...
