In a ball mill, the particles are ground by repeated impact forces. the material needs usually more than 20 minutes from mill entrance to outlet, uncountable impacts take place on this way. depending on the efficiency of the separator and the grinding aid, agglomerates of fine particles are rejected and pass the ball mill.In previous publications, we have described how the size specific energy (sse) can be calculated to predict the energy required to generate new minus 75 m material. however, if we want to benchmark the performance of fine grinding where the product can be much finer than 75 m, clearly we require a finer marker size. if we do this, we also need a way to compare results.

Best Grinding Mill

In the case where wet grinding is possible, a rod mill would be most suitable as the over grinding to below 200 micron would be minimized. a ball mill will tend to produce more unwanted fines. i also agree with regard to the hpgr. what you want to avoid as much as possible would be impact grinding as this will generate too much.It is also well known that the industrial work horse for fine grind ing, the wet or dry ball mill, for various reasons, becomes more and more inefficient for sizes less than k80 75 //m, and especially consi-sidering sizes less than k80 45 pm. since breaking/crushing of the particles propagates by cracking.
