The autogenous mill will grind the material to the extent that the content of the particles with particle size <0.074 mm accounts for 20–50% of total quantity of product, and crushing ratio is 4000–5000, which is over 10 times that of ball mill and rod mill. The maximum particle size of the lump ore fed into autogenous mill is 300–350 mm.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. …

A specific energy-based size reduction model for batch grinding ball mills was reported in a previous paper (Shi and Xie, 2015). A discharge function modified from the Whiten classification efficiency equation has been incorporated in the size reduction model to extend its applications from batch grinding to continuous operation.

Ball trajectories for 4 mill revolutions at 66%, 83%, and 93% critical speed. The instantaneous radial and tangential velocity distributions at the end of three revolutions of the above mill rotated at 83% critical speed (i.e., 25 rpm) are given in Fig. 2. As may be expected, the average radial velocity is almost zero.
