A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
Efficient: high capacity and fineness. operation: automatic. grinding way: Crushing ratio up to 4000 to 5000, than the ball mill, rod mill ten times higher. ore is to grinding by itself, selective grinding stronger, less than crushed, therefore, easy sorting, will help to improve beneficiation indicators improve .
Similarly, the net efficiency of the ball mill will have the same value, in this case, for any monosize feed to the ball mill at any other size distribution, that is, any other X 50 of the product, since the lines for single-particle breakage and ball mill grinding are parallel.
