Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.

While the mill main drive accelerates the operator has to watch the development of the power consumption of the mill main drive and of the differential pressure of the mill. When the usual values are reached the start command to the feed group is given. During the first 5 to 15 minutes of operation the mill has to be stabilized.
What are the causes for an increase of Cement Mill trunnion Bearing temperature and what are the possible solutions . Cement mill trunion bearing temperature may increase due to following reasons: 1. HP pump pressure is low. 2. Cutoff time of HP pump after mill start up; 3. Mixing of contamination with oil; 4. LP pump oil flow is less; 5.
While this is not standard practice in cement production, cement plants in countries like India are often located far away from energy sources, so they rely on their own sources. Power generation typically involves direct firing systems. There is an air swept mill with direct pneumatic conveying through to the burners.
