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.

1. Our rotary cement kilns are all made of thermal insulation material, which reduces the radiation heat loss and energy consumption during the burning process; 2. We use the compound fish scale to soft seal the front end and the back end of the rotary cement kiln. The air leakage coefficient can be thus controlled less than 10.
