Raw Mill Feeding. In the value stream map of cement manufacturing the raw mill feeding is an intermediate activity between Pre-homogenization and raw milling, and has not been discussed separately by most of the authors. However, in my opinion it remains and must remain as of pivotal importance, so far as the quality assurance is considered.

This grinding is done using either ball mills or vertical roller mills (VRM). The raw material is simultaneously dried. Ball mills use impact with attrition principles for grinding the raw material. Inside the ball mills, various sizes of balls are used and classifying liners are used to maintain the position of different sizes of balls.

1. Steel Balls. Steel balls are one of the most widely used grinding media in cement ball mills, their diameters can range from 20mm to 120mm according to different grinding requirements. In a cement ball mill, generally, φ50–100mm steel balls are used in the coarse grinding chamber, φ20–50mm steel balls are used in the fine grinding chamber.
