This plant has 2 lines for cement production (5300 t/d). The ball mill has one component, m diameter, and m length with 240 t/h capacity (made by PSP Company from Přerov, Czechia). The mill's rotation speeds are mainly constant (14 rpm), and there is approximately a fixed oneyear period of changing liners.

The energy consumption of the total grinding plant can be reduced by 2030 % for cement clinker and 3040 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended.

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.
