Feb 01, 2021 In addition to ball mills, one of the other common mills in factories is the vertical roller mills (VRMs). In contrast to grinding by ball mills that need other devices to dry and separate powder, VRM performs separation, grinding, and drying processes just in one machine and reduce the number of devices in a close circuit.
