Ball Mill Crushing by tube-mills were first introduced into the crushing departments of cyanide plants when it was found that for crushing finer than 30-mesh other types of crushing machinery were not efficient. In order to crush with one pass, these mills were made 18 to 22 ft. (5.5 to 6.7 m.) in length. Pebbles were used as a grinding …
Hammermill Crushers are known to generate material finer than 3/16" (4mm), which in some applications may be undesirable. However, if there is a market for finer material, or if it is acceptable within the desired product size, Hammermills can achieve reduction ratios that may otherwise require multiple crushers.

Crushing devices hold feed material between two solid surfaces and apply sufficient force to fracture or deform that material. Primary crushing operations takes boulder size feeds (20 to 100 inches) and reduces the material to secondary crusher feed size (1 to 20 inches) or mill feed size (0.5 to 3 inches).
It is performed in cylindrical steel vessels that contain a charge of loose crushing bodies—the grinding medium—which is free to move inside the mill, thus comminuting the ore particles. According to the ways by which motion is imparted to the charge, grinding mills are generally classified into two types: tumbling mills and stirred mills ...
