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.
ABC closed circuit, Autogenous-Ball-Mill-Crusher. Another similar technique is the ABC open circuit where the crusher product feeds the ball mill rather than the autogenous mill. Crusher product is typical feed to a ball mill using large diameter balls but not much grinding of 20-25 mm ore can be accomplished in an autogenous mill.

You also need a rod mill work index to design a ball mill operating on a coarse feed, above about 4 mm. Q1: You design for a typical percentage of critical speed, usually 75% of critical. Then you iterate the mill diameter using a Morrell C-model or equation to get the RPM that corresponds to 75% for that mill diameter.
Stamps were the most common way to crush ore for many decades, but by the first few decades of the 1900s the ball mill started replacing stamps.
