The cement rotary kiln. When operating the vertical roller mill, the operator must control the inlet and outlet air valves to make the air volume of the system in a balanced state, so as not to affect the air pressure at the back end of the rotary kiln. We are AGICO, a professional cement equipment manufacturer and cement plant contractor.

the specific power consumption of a ball mill is higher than that of a vertical roller mill (VRM) carrying out the same oper - ations by a factor of between 1.5 and 2, depending on the

• a vertical roller mill installed with a minimum of civil works, i.e. as shown in Figure 9. Installed mill power: 3750 kW. System capacity: 204 t/h. The comparisons are exclusive of mill feed arrangement, silo battery for mill feed materials, cement transport and cement silos, as these items are identical for the two systems.
