Ball Mill
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 outlet.
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.
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
1. Adding fine crusher before the ball mill.
2. Improving grinding system to achieve better grinding efficiency.
3. Adding powder concentrator...
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.
Usage in Aerocrete Equipment:
Coal ash (or sand, stone powder) are conveyed to 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 ball mill through a spiral conveyor. Finally, fine grinded materials are delivered to stock bin through a spiral conveyor and a bucket lifter.
