Coal 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 Coal ball mill is made up of lining
plate, grate plate, diaphragm, feeding and discharging devices. 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. The lining plate is used to protect
the tank body in order to avoid the impact and abrasion from
materials.
Minerals are firstly crushed by jaw crusher until they are crushed
to suitable sizes. They are then equally fed to a Mining ball mill with a
hoister and a feeder. Later, they are further crushed and milled in the Mining
ball mill. Finally, fine minerals are classified by a spiral classifier with the
principle that solid particles sink at different speeds in liquid.Usage in
Aerocrete Equipment:
Coal ash (or sand, stone powder) are conveyed to Coal
ball mill through electric vibrating feeder and rubber belt conveyor. Grinded
coal ash (or sand, stone powder) is delivered to slurry tank for storage through
a coal ash pump. Lime is conveyed to jaw crusher by electric vibrating feeder
and rubber belt conveyor. The crushed lime firstly is stored in a limestone
storage silo with a bucket hoister. Then, it is conveyed to Coal ball mill
through a spiral conveyor. Finally, fine grinded materials are delivered to
stock bin through a spiral conveyor and a bucket lifter.
Dry ball mill is generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with dry , they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various , such as screens, spiral classifiers, cyclones and air classifiers are used for classifying the discharge from dry ball mills.
Dry ball mill is an efficient tool for grinding many materials into fine
powder. The dry ball mill is used to grind many kinds of mine and other
materials, or to select the mine. It is widely used in building material,
chemical industry, etc. There are two ways of grinding: the dry process and the
wet process. It can be divided into tabular type and flowing type according to
different forms of discharging material.
