The ball charge and ore charge volume is a variable, subject to what is the target for that operation. The type of mill also is a factor as if it is an overflow mill (subject to the diameter of the discharge port) is usually up to about 40-45%. If it is a grate discharge you will have more flexibility of the total charge. Ball size and ball grade is determined by the feed ore size and hardness ...

In this work, a cement ball mill (CBM) of a new generation cement plant is considered as a case study in order to study its efficiency based on both first and second laws of thermodynamics. Also, for the first time, the effects of ball charge pattern, cement fineness and two additive materials (pozzolan and limestone) on the efficiency of the CBM are investigated. Actually, the literature ...

Optimization of the Cement Ball Mill Operation. Optimization addresses the grinding process, maintenance and product quality. The objective is to achieve a more efficient operation and increase the production rate as well as improve the run factor. Consistent quality and maximum output with lower specific power consumption results in lower operating costs per unit of production. Optimization ...
The L/D ratio of the ball mill was varied in four steps of 1.75, 2.1, 2.79 and 3.49, and the ball charge filling ratio was varied in three steps of 15%, 20% and 25%. The experiments clearly indicated that the optimal L/D ratio and the optimal ball charge filling ratio are different for each feed fineness.
