Know About Wear

Wear is the deterioration of a component causes due to the friction of material, slag, cement, and so forth. Plant machinery and components mainly get affected and the result is huge losses and expensive maintenance cost. To combat these losses, we provide Wear Resistant Lining Solution ideal for various industries like coal, power plants, food, cement, fertilizer, mining, and others. We have robust manufacturing plant to develop Wear Resistance Ceramics with improved features that help in Abrasion Resistant Lining of plant components such as coal mill equipment, ash handling bends, grinding media, scrapper conveyor, and others. Wear Solutions offered by us reduce the maintenance cost and improve productivity.
