get priceBall mills are also used for the particle size reduction of black powder, cement, fertilizer, silicates and even a variety of ferrous and non-ferrous metals. Ball mills are very similar in design and operating concept to rock tumblers, which used milling media to polish rocks in a rotating cylinder.

get price2017-2-20 All Grinding Mill & Ball Mill Manufacturers understand the object of the grinding process is a mechanical reduction in size of crushable material. Grinding can be undertaken in many ways. The most common way for high capacity industrial purposes is to use a tumbling charge of grinding media in a rotating cylinder or drum.
