Vertical Roller Mill Working Principle When the vertical mill works, the motor drives the grinding disc to rotate, and the grinding roller rotates around the grinding roller shaft driven by the disc. The material entering from the feeding port falls in the center of the grinding disc and moves towards its edge under the action of centrifugal force.
