12. If the rate of feed increased, coarser product will be obtained and if speed of rotation is increased the fineness for a given capacity is increases. During grinding, the balls themselves wear and are continuously replaced by new ones so that mill contains balls of various ages. Ball mill produces 1 to 50 ton/hr of powder and energy requirement of the ball mill is about 16 kwh/ton.

The tumbling mill principle is based on the impact and attrition of the grinding media against the materials to be ground. As the cylinder rotates, the grinding media falls, collides, and crushes the materials inside the cylinder. The impact of the grinding media generates heat, which can affect the quality of the final product.

A cement's total weight is composed of 60% tricalcium silicate (C3S), 15% dicalcium silicate (C2S), and 10% tricalcium aluminate (C3A), and 8% tetra calcium aluminoferrite. C3S makes up 50% of the total weight of OPC, therefore it can be seen that the composition of Rapid Hardening Cement comprises a higher percentage of C3S than OPC.
