The 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.
Working Principle:
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.
Structure:
The machine is composed by feeding part, discharging
part, turning part and driving part (reducer, small
driving gear, electric motor and electric control).
The quill shaft adopts cast steel part and the liner
is detachable. The turning gearwheel adopts casting
hobbing process and the drum is equipped with
wear-resistant liner, which has good
wear-resistance. The machine is with stable and
reliable working condition.
Moreover, according to different materials and
discharging methods, there are dry ball mills and
wet ball mills for choice.
