The ball motion in the mill was simulated via discrete element method (DEM). Our results show that steel balls achieved faster breakage of clinker into finer particles than alumina balls, which was explained by the higher totalmean energy dissipation rates of the steel balls. The PSD became finer as smaller balls were used.

A material mixture is kept in a bin with a capacity of 70 t that is supplied by a cement ball mill. Dust and fly ash are supplemented after the ball mill depending on the required kind of cement. The cement is then transferred through a bucket elevator to the next separator. Particles comprise the final product that is supplied to the cement silo.

The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (nonspherical, irregularly shaped and mixedsize media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%15% above the ball charge for total of 23% ...
