Founded in 1984 with the acquisition of the EIMCO ball, pebble and rod mill product lines. Neumann Machinery Company (NMC) is headquartered in West Jordan, Utah, in the USA just 14 miles south of Salt Lake City.

The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the ratio "length to diameter" and this ratio most frequently varies from 0.5 to 3.5. The

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a …

The ball mill is a rotating cylindrical vessel with grinding media inside, which is responsible for breaking the ore particles.
