Ball Mill for Mining Industry and Cement / Ore Grinding Mill Sale
Introduction:
Ore ball mill is used to separate and screening different ore
minerals, separate ore tailing. It also be used for ore grinding,
non-ferrous metal beneficiation, new-type building material
producing.
According to the discharge method, the ball mill divided to
dry-type mill and wet-type mill.
Our Project Cases: Ball Mill in Zambia
Capacity: 500t/d
Process: two stages one close-circuit crushing, one stage
one-circuit grinding and classification, one roughing-two
scavenging-ten cleaning.
Structure:
Ore Ball mill is mainly consisting of feeding device, big gear,
discharge device, cylinder, diaphragm plate, hollow shaft, liner,
drive device and other components.
1. The feeding device is consisting of inlet chute and screw. There
are liners in the inlet chute, which can extend the working life of
the feeding device.
2. There is pre-gap on the inlet hallow shaft, that can reduce the
tolerance which is made of temperature changes and installation
mistake to ensure the gear mesh.
3. Inside the ball mill, different parts have different liner
structure, which will greatly improve the grinding efficiency.
4. Dry-type ball mill adopt sliding bearing, which is good of
strength, ductility, antifriction, abrasion resistance, lubricity
and thermal conductivity. It is able to meet the lubrication
requirements of the hollow shaft. That is suitable for the
environment of low speed and heavy load in metallurgical & ore
dressing industry.
5. Wet-type ball mill adopt roller bearing, reduce useless work
consumption and easy to replace.
Working Principle:
The ball mill is composed of a horizontal cylinder, a hollow shaft
for feeding and discharging materials, and a grinding head. The
cylinder is a long cylinder. The cylinder is equipped with an
abrasive body. The cylinder is made of steel plate. A steel lining
plate is fixed to the cylinder. The abrasive body generally, it is
a steel ball, and it is loaded into the cylinder according to
different diameters and a certain proportion. The grinding body can
also be used in the steel section. The material is selected
according to the particle size of the grinding material. The
material is loaded into the barrel by the hollow shaft at the feed
end of the ball mill. When the barrel of the ball mill rotates, the
grinding body is attached to the barrel lining plate due to the
inertia and centrifugal force and friction. Taken away by the
cylinder, when brought to a certain height, it is thrown down due
to its own gravity. The falling abrasive body crushes the material
in the cylinder like a projectile.
