The crushing kinetic process of the cement clinker in a CKP mill is analyzed, by using the particle size distribution and mass balances. The following results have been obtained. 1.Process - Ball Mill Heating and Cooling - Clinker Cement,,For ball mills, 90% of the mill motor power gets converted into heat. For bowl mills, it's about 75%. Often when we need to dry materials, heat from the motor is not enough and we are then forced to bring in an additional heat source (furnace, hot gases from the kiln or cooler). Sometimes this extra heat is added to the separator and the fresh feed is sent there first. This arrangement is called flash drying.

ÖZET: ABSTRACT: 1. GİRİŞ
ABSTRACT: The kinetics of dry grinding of various feed sizes of cement clinkers was investigated in a laboratory tumbling ball mill. The grinding kinetics process is first order, and the S, values (specific rates of breakage) decreased, as the feed sizes decreased. However, the B KJ values (cumulative breakage distribution function) were changed, while the feed sizes changed; although they,cement ball mill_Ball mill,Lime ball mill,Beneficiation,,Cement ball mill process.
