A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage [1]) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills.

Then, cooled clinker ground in a ball mill. For the prevention of flash-setting of the cement 3 to 5 % of gypsum is added. Ball mill is a hardened steel ball that has different chambers that charged in sequence forward. The particles are crushed into the required fineness level. And particles are separated by air currents and taken to storage.

The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time

According to the needs of different customers, there are two types of cement ball mill: open-flow mill and circular-flow mill.
