The mix of media and ore rises and falls in the mill like clothes in a ...

Ive used a rod mill,impact mill, but this is the best bet for fine grind. Yes those are steel balls they are about 8lbs each i use 5 to grind a 5gallon bucket of 1/8 classified material. I try to break the ore up as small as i can while mining. It will handle 1/2 inch clasified but its hard on the tool. so 1/8 is best. Intructions

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 cylindrical shell rotating about its axis. T
