When mixed with water, Portland cement hydrates and forms heat 3CaO·SiO2+H2O CaO·2SiO2·3H2O+Ca(OH)2 Triealcium silicate hydrates rapidly and forms earlier strength and earlier heat of hydration. Tricalcium silicate is formed in a kiln when the charge contains an abundance of lime, and hence the greater amount of CaO in the reaction.

The profiling of the shell lining plates creates the movement of the ball charge, which causes the grinding of the material. It is therefore essential for effective grinding in the mill and far more than just a wear part. The exact profile shape has to be defined depending on the ball sizes used, the rotation pace and the mill diameter.

The effect of mill charge is primarily through the shifting of the center of gravity and the mass of the charge. As the charge increases the center of gravity moves inward. The power draft is more or less symmetrical about the 50% value. A simple equation for calculating net power draft is P 2.00 3 cD 2.5 m LKl kW (8.12)
