Another heritage company, Allis-Chalmers, made the first ball mill in 1898. It also made the first hydro cone crusher and was one of the first companies to modernize the primary gyratory crusher with a design that allowed for easier operation and maintenance. "What they made in the 1950s is actually very market even today," Jacobson says.

The Effect of Grinding Media on Mineral Breakage Properties ... - Hindawi

The breakage and liberation of minerals are the key to fluidized mining for minerals. In the ball milling process, steel balls function as not only a grinding action implementer but also energy carrier to determine the breakage behavior of ores and the production capacity of the mill.

Comminution in HPGR is a result of high inter-particle stresses generated when a bed of solids are compressed while moving down the gap between two pressurized rolls. The priority that HPGR can generate fine products followed by grinding in ball milling, puts a competitive pressure on the application in semi-autogenous (SAG) mills.
