A ball mill is a key equipment for crushing materials after they have been crushed. Ball mills are widely used in the production industries of cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal beneficiation, and glass ceramics. They perform dry or wet grinding on various ores and other grindable materials.
Working principle of ball mill:
The ball mill is a horizontal cylindrical rotating device, driven by external gears, with two compartments and a grid type ball mill. The material enters the first chamber of the mill uniformly through the feeding device through the feeding hollow shaft screw. There is a stepped lining plate or corrugated lining plate inside the chamber, which is filled with steel balls of different specifications. The rotation of the cylinder generates centrifugal force to bring the steel balls to a certain height and then drop them, producing a heavy impact and grinding effect on the material. After the material reaches rough grinding in the first warehouse, it enters the second warehouse through a single-layer partition board. The warehouse is embedded with a flat lining board and steel balls inside, which further grind the material. The powdered material is discharged through the discharge grate to complete the grinding operation.
The ball mill has strong adaptability to fluctuations in the physical properties of materials, such as particle size, moisture, hardness, etc;
Low metal consumption per unit product, compact structure, stable operation, and easy operation and maintenance;
The lining plate is cast from high-quality wear-resistant materials, which are wear-resistant, have a long service life, high production capacity, and a large crushing ratio, and can adapt to different operating conditions;
The product has fine fineness and uniform particle size, easy adjustment of particle size distribution, high product qualification rate, good sealing, low dust pollution, high grinding efficiency, and low energy consumption.
