Wholesale Good Quality Wear Resistant Superior Density China High Al2O3 Alumina Lining Brick/ Block/ Liner/ Board for Ball Mill

Alumina lining brick is widely used in ceramic, paints, color, cement, coating, refractory material, pharmaceutical, chemical, mine industry etc.

The advantages are super hardness, high density, low wear loss, regular shape and good corrosion-resistance etc. The microcrystalline wear-resistance alumina lining brick can be divided into rectangular brick, trapezoidal brick and irregular brick as shape. The product features with high hardness and density, low wear rate, good neat and anti-corrosion.

Ceramic lining bricks

Ceramic lining bricks have the characteristics of high strength, high fracture toughness, low wear, good regularity, impact resistance, abrasion resistance, scientific formulation, dry pressing and high temperature firing. The Mohs hardness is 9, second only to diamond. The construction is convenient, the theoretical wear resistance is 300 times that of manganese steel, and the service life can generally reach 10 times.

Wear-resistant ceramic lining brick is an anti-wear product embedded in the inner wall of the ball mill. It can also be used in refractory materials, electronics, ceramics, and high-temperature kilns, which can effectively improve grinding efficiency, reduce grinding costs, and reduce product pollution.

Advantages of Ceramic Linings in Ball Mills

Enhanced Wear Resistance

During operation, ball mills are continuously subjected to impact and friction from grinding media and materials, which can easily cause wear to metal liners. Ceramic materials, with their high hardness and exceptional wear resistance, effectively withstand the impact and friction from grinding media and materials, thereby improving the wear resistance of the ball mill.

Extended Service Life

Thanks to their excellent wear and corrosion resistance, ceramic linings significantly extend the service life of ball mills. Compared to traditional metal liners, ceramic linings have a longer lifespan, reducing the frequency of equipment maintenance and replacement, and thereby lowering production costs.

Improved Work Efficiency

The smooth surface of ceramic linings minimizes material adhesion, reducing energy loss during ball mill operation and enhancing work efficiency. Additionally, ceramic linings reduce friction and wear between materials inside the mill, improving product quality.

Reduced Noise and Energy Consumption

Ceramic linings offer better sound insulation compared to metal liners, effectively reducing the noise generated during ball mill operation. Due to their superior performance, ceramic linings also lower the energy consumption of ball mills, reducing production costs.

Environmental Friendliness and Energy Savings

Ceramic materials are environmentally friendly and do not cause pollution. The use of ceramic linings reduces waste emissions during the production process, contributing to environmental protection. Furthermore, by lowering energy consumption and reducing maintenance frequency, ceramic linings help enterprises save energy and cut production costs.
