Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Httpd Wiki" for change notification.

The "ball mill" page has been changed by sbmzhcn.


New page:
As a piece of mineral processing equipment, a ball mill is widely used in beneficiation, building
material and chemical industries. Ball mill is suitable for dry-type ore grinding and wet-type
ore grinding. According to different discharging methods, ball mills fall into grate ball
mill and overflow ball mill .

== Working Principle: ==
Our ball mill is of horizontal, cylindrical and tubular structure. It comes with two cabins
and is a grate ball mill. The materials are evenly fed through the charging device to first
warehouse where there are step scales boards, corrugated scale boards and different specifications
of steel balls. When the cylinder rotates, the centrifugal force produced causes the steel
balls to impact and grind the materials in the ball mill. The materials are then lead to the
second cabin for further milling until they turn into powders and are discharged from the

== Ways of Improving Productivity: ==
In addition to manufacturing ball mill, we also carry our research on improving its productivity.
Generally speaking, the productivity of ball mil can be improved by
 * adding fine crusher before the ball mill.
 * improving grinding system to achieve better grinding efficiency.
 * adding powder concentrator..

== Range of Applications: ==
Ball mill is a mineral processing machine for milling the materials into powders after they
are crushed. It is widely applied to the production of cements, silicate products, building
materials, fireproof materials, fertilizers, glass, ceramics as well as nonferrous and ferrous
metal processing industries. It could carry out dry and wet millings on different materials.

== Structural Features: ==
This ball mill is made up of feeding part, discharging part, gyre part, transmission part
(transmission part includes reducer, small transmission gear, generator and electrical control)
and so on. It enjoys features like good abrasive resistance, stable and reliable operation.
Inner structure of the ball mill is made up of lining plate, grate plate, diaphragm, feeding
and discharging devices. The lining plate is used to protect the tank body in order to avoid
the impact and abrasion from materials. Different types of lining plates can be used to adjust
the movement of materials. Our lining plates are provided by Luoyang anti-abrasion academe
and have a large share in the global market with their fine design.

== Usage in Mineral Processing: ==
Minerals are firstly crushed by jaw crusher until they are crushed to suitable sizes. They
are then equally fed to a ball mill with a hoister and a feeder. Later, they are further crushed
and milled in the ball mill. Finally, fine minerals are classified by a spiral classifier
with the principle that solid particles sink at different speeds in liquid.
