Industrial crushers reduce large rocks, ore, or waste materials to smaller sizes. They are the first level of size reducer; further granularization occurs in grinding mills or pulverizers. Crushing devices hold feed material between two solid surfaces and apply sufficient force to fracture or deform that material.

Crushers have more efficient transfer of applied power to the breakage of rock than grinding mills. Typically a crushing flowsheet for a mineral processing plant will have from onetothree stages of crushing. There are some cases where the process requires a fine dry product and a quaternary stage of crushing will also be included.

The mill is filled with suitable grinding media, and the space between each of the disks is essentially an individual grinding chamber. As a result, the mill effectively comprises eight grinding chambers in series. The media is set in motion by the action of the grinding disks, which accelerate the media nearby radially toward the shell.

With an autogenous mill the power drawn by the mill may become the limiting factor to further feed rate increases. In this case when the maximum desirable power is reached, the power control overrides the density control. The power control System is almost identical to that described in the crushing section of this paper.

The cost of grinding with Hardinge Mills is remarkably low. It has been found, by comparing the operation of Conical Mills with cylindrical tube mills in the grinding of ore and limestone, that with the same ball load in both types of mills, the cylindrical mill will consume about 60 per cent, more power for the same work as will the Conical Mill.
