Jul 31 2014 · Due to limitation of the mill s rotational speed the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills (Pilevneli and Azizli 1999) indicates that using smaller media (5-8 mm range) improves grinding energy efficiency up to 50 using stirred mills.

Chat Online### 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
