The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and nonferrous metals. The ball mill can grind various ores and other materials either wet or dry.
Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc. The applications of ball mills are ubiquitous in mineral
Ball and Pebble Mills Both mills utilize tumbling media. Ball mills use steel balls and pebble mills use ceramic or natural rock for grinding. Operating in open or closed circuits, ball and pebble mills are designed for long life and minimum maintenance. Rod mills rod mills are used in both wet or dry applications for a wide range of ...
A stamp mill consists of a set of heavy steel (ironshod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is repeated at the next pass of the cam.
