Ball mill is a key equipment to grind the crushed materials, and the ball mill is
widely used in powder-making production line including cement, silicate, new-type
building material, refractory material, fertilizer, ore dressing of ferrous metal and
non-ferrous metal, glass ceramics, etc. And the ball mill can grind various ores and
other materials with dry type and wet type. There are two kinds of ball mill, grate
type and overfall type due to different ways of discharging material.

The ball mill is a horizontal rotating device transmitted by the outer gear. The
materials are transferred to the grinding chamber through the quill shaft uniformly.
There are ladder liner and ripple liner and different specifications of steel balls in
the chamber. The centrifugal force caused by rotation of barrel brings the steel
balls to a certain height and impact and grind the materials. The ground materials
are discharged through the discharging board thus the grinding process is
finished.
