How does a vertical roller mill work?

In the vertical roller mill which is widely used in the raw material grinding process, raw materials input grinding table are crushed and pulverized on it and transported to separator by kiln exit gas introduced into the mill as drying, transporting and separating purpose.

What is the principle of roller mill?

Roller mills use the process of stress (which is applied by the rotating wheels) and attrition in milling of solids in suspensions, pastes or ointments, and some solid materials. The rollers rotate at different speeds and the material is sheared as it passes through the gap.

The roller mill minimizes such costs by precisely reducing feed materials with an average particle size up to 3⁄4 inch to a uniform average size typically between 100 and 2,000 microns.

How do you clean metal rollers?
