Operation and Elements of a Closed Circuit Ball Mill System. Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media and lined with lifting liners. The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber.
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
The major operations carried out in the cement raw material milling are as follows: Crushing of limestone, coal, and other materials. Storage arid blending of raw materials. Preparation of raw mix. Raw mix grinding and homogenisation. Pyro processing of raw materials in the kiln. Cooling and storage of clinker.

The grinding of materials is more sufficient. In the raw mill grinding process, the grinding material is discharged from the grinder through the discharge hole, and the fineness of the qualified material is sorted by the sorting equipment, while the fineness of the unqualified material is sent back to the cement raw mill by the sorting machine.
