In the extensive conveying systems of mines, power plants and steel mills, the friction and wear between the drive drums and the conveyor belts have always been the key factor limiting the lifespan of the equipment. Traditional metal rubber coatings often fail quickly when dealing with highly abrasive materials, leading to frequent shutdowns. However, the mosaic ceramic pulley laggings - a special material composed of ceramic pieces and an elastic matrix - is revolutionizing the industrial anti-wear standards with its revolutionary wear resistance and anti-slip properties.

The mosaic ceramic pulley laggings is not a single material, but a "flexible and tough" composite material. It is composed of alumina wear-resistant ceramic pieces and high-temperature resistant rubber. The alumina ceramic sheet uses pure alumina (Al?O?) with a purity of 92% or higher, and its hardness reaches 9 on the Mohs scale (second only to diamond), with a wear resistance more than 266 times that of manganese steel. Common shapes include hexagonal, square, or custom mosaic with pits (common sizes: 17.5×17.5mm, 20×20mm, hexagonal φ12/19mm, etc.), and the raised surface structure can enhance the friction coefficient. The alumina ceramic and high-temperature resistant rubber (such as nitrile rubber) are bonded into plates to form standard gaskets of 300×300mm, 500×500mm, etc., and the rubber layer provides elastic buffering to reduce the impact on the conveyor belt.

The application scenarios of mosaic ceramic pulley laggings: comprehensive coverage from mining to new energy.

1. Protection of key components of the conveying system

Rubber coating on the drive drum: Ceramic rubber sheets are directly attached to the surface of the drum, replacing the traditional metal coating;

Slope/pipe liner: Ceramic mosaic tiles protect against the impact and wear caused by block materials (such as ores and coal);

2. Special Industrial Equipment

Fan blades, crusher teeth plates, ore dressing machine drums: Ceramic sheets are strengthened locally through bonding or welding;

Robot joint friction pads: Ultra-thin ceramic coating (0.5μm) replaces the nickel-phosphorus coating containing diamonds, achieving both environmental protection and high performance.

3. Expansion in emerging fields

In scenarios such as lithium battery raw material transportation and waste incineration power plants, their corrosion resistance and high-temperature tolerance enable long-term operation.
