ALUMINA CERAMIC LINER
Alumina ceramic liner is a high-performance wear-resistant ceramic piece made of industrial alumina powder as raw material and sintered at high temperature. It has the characteristics of high hardness, excellent wear resistance, corrosion resistance, high temperature resistance and low friction coefficient.
Products are widely used in material conveying systems in coal, cement, steel, mining, electric power, and port machinery. They protect equipment surfaces from impact and wear, greatly extending equipment service life and reducing maintenance costs.
Protects hoppers, transfer chutes, and conveyor equipment from abrasive coal wear in processing operations.
Critical protective liners for raw material hoppers, clinker chutes, and grinding mill liners.
Applied in ore handling equipment and blast furnace charging systems for extreme wear resistance.
