7 Differences Between Ball Mill and Rod Mill

In the second stage grinding process, the rod mill is generally used as the first stage grinding equipment with larger production capacity and high efficiency. For dealing with those soft or not too hard ores, the rod mill can be used in fine crushing rather than cone crusher, which not only has a simple configuration, low cost, but also simplify the dust removal of the workshop.

Ball mill

A ball mill is a type of grinder used to grind or 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. A ball mill consists of a hollow ...
