Ball charge optimization - INFINITY FOR CEMENT

Ball charge optimization TYTP Power Best Practice ... The raw mill will be operate with a much coarser ball charge than the cement mill mainly because of the bigger slot sizes of the partition wall. The transition zone consists of 50 mm and 60 mm balls. The basis is a 50 mm ball size for 5% residue on the 4 mm sieve. In case bigger grains are by-passing the partition through the center grate ...

Optimization of continuous ball mills used for finish ...

The number of stresses can be characterised by the average retention time of the ground material inside the mill if the ball charge grading remains unchanged. The optimal retention time depends not only on the feed material and the desired comminution result but also on the ball charge filling ratio and particularly on the L/D ratio. On the basis of the present results and considerations, a specific optimisation of ball mills

Optimization of Cement Grinding Operation in Ball Mills ...

Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media and lined with lifting liners. The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber. It is lined with classifying-type mill shell liners and provided with finer ball charge. Classifying ...

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 ...
