2004-12-10  Furthermore, it has shown that a L/D ratio of about 3.0, which is a quite common value for cement mills, might be to high for a ball mill in a Combi-grinding plant. This was proven by the fact that there was no grinding progress observed in the last third of the total grinding path length. This finding was not effected by different ball charge filling ratios and different mill throughput mass ...

OPTIMIZING THE CONTROL SYSTEM OF CEMENT MILLING:

mostly performed in closed circuits: The ball cement mill (CM) is fed with raw materials. The milled product is fed via a recycle elevator to a dynamic separator. The high fineness stream of the separator constitutes the final circuit product, while the coarse material returns back to the CM to be ground again. A simplified flow sheet, showing the basic compo-nents of a closed grinding system ...

2004-12-10  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.

How to Improve Ball Mill Performance

Application of value engineering techniques to grinding process modelling led to the identification of two basic functions of the ball mill-classifier circuit. In terms of a specified circuit product size which is used to differentiate between “coarse” or oversize material and “fines” or undersize material, these basic functions are (a) breakage of the coarse material and (b) removal ...
