Product Introduction
The cylinder mixer of sintering machine with ordinary lining plate as its lining generally has the following problems: the lining is not wear-resistant, the cylinder is seriously hung up, the tail of the cylinder is poured, the labor intensity of the operator is large, the equipment load is large, the tire group is seriously worn, the cylinder moves greatly, and the failure is frequent, which restricts the production capacity of the closing machine.
Wear resistant alumina special-shaped liner can solve these problems. Wear resistant ceramic lining plate has high strength, high hardness, strong wear resistance, can be pasted, welded and fixed, impact resistance, obvious anti falling function; temperature resistance, long life, more than 30 times of the life of ordinary steel, light weight, density of more than 3.6g/cm3, only half of the steel, can greatly reduce equipment load, low price, and can be used in a short time after construction.
Common specification of wear-resistant ceramic lining plate: unit: mm note: products of different specifications can be made according to customer requirements.
Feature
Wear resistant alumina special-shaped liner products have the characteristics of good wear-resistance, impact resistance and convenient construction. Its theoretical wear-resistance is 260 times of that of manganese steel and 170 times of that of chromium steel. The products are used for the inner and outer surfaces of material conveying equipment and powder concentrator in steel, power, coal, cement and other industries, which can effectively extend the service life of the equipment.
