Application of alumina wear-resistant lining brick in ball mill
Alumina wear-resistant ceramic lining bricks can increase the service life of ball mill linings. We analyze from the following perspectives:
Working principle of ball mill:
As an important equipment for refining solid materials, ball mills are widely used in construction, cement, metallurgy, chemical, ceramics, electric power, medicine, and defense industries. When the ball mill is working, the materials are passed through the feeding device through the hollow shaft spiral. It evenly enters the mill. The mill is equipped with grinding media of different specifications. The centrifugal force generated by the rotation of the cylinder will bring the grinding ball to a certain height and then fall down, which will cause heavy blow and grinding effects on the material.
Wear mechanism of ball mill:
The main function of the liner of the ball mill is to protect the mill. When the mill is rotating, the grinding balls and materials in the mill are brought to a certain height by the liner and then thrown or dropped to grind and crush the materials. The liner is in operation. The impact, sliding and rolling effects caused by the steel balls and materials are also affected by the temperature, so the main failure mode of the liner is the abrasive wear under multiple impacts with small energy. Under abrasive wear conditions, wear resistance directly affects the service life of parts, so the material of the liner and the amount of wear are important factors that affect the service life of the ball mill liner.
Advantages of alumina wear-resistant ceramic lining bricks:
Alumina wear-resistant ceramic lining bricks can be used as the inner lining of ball mills. It has the characteristics of high hardness, high density, low wear, good regularity, corrosion resistance, etc. It is used in ceramics, cement, paint, pigments, chemical industry, medicine, coatings, inorganic mineral powder and other industries, which can effectively improve the grinding efficiency and reduce Grinding cost, reduce product pollution.
Features of microcrystalline wear-resistant ceramic lining bricks:
1. Its main component is alumina, with high purity, which greatly reduces the pollution caused to grinding materials
2. Good wear resistance, which is 266 times that of manganese steel, effectively prolonging the service life of the equipment
3. Match with high alumina ball to grind fine slurry,
4. Corrosion resistance, high density, high mechanical strength, etc.
