Energy Required For Water Evaporation In Vertical Roller Mill

Tube mills are the most energy intensive of the four mill systems.3 - Vertical Roller Mill materials are crushed between a rotating grinding table and 2 to 4 grinding rollers positioned slightly less than 90 degrees from the table surface and pressed hydraulically against it. Vertical roller mills use 70-75 of the energy used in tube mills.
