Wear Resistant Products

Hofmann now offers Ceratuff high alumina ceramic lined equipment for highly wear prone application such as coal fired power generation, mining, cement, steel, mineral processing industries. This is designed to meet exacting requirement in cost effective manner. The choice of high alumina product ensures excellent wear and corrosion resistant properties. The company offers services for application development including material selection, lining design, fabrication and installation. Alumina shape, size shall be designed to suit the final application of the equipment. The installation of the liner is done by high alumina based wear resistant bonding material and/or welding. The hardness of Ceratuff is next to diamond, which ensures extremely hard and wear resistant material. It can last longer than any other conventional material to take abuse of bulk material handling. In addition it retain its highly wear resistant properties at high temperature. Ceratuff is also inert to all most all chemicals and thus providing excellent corrosion resistant properties against chemicals. Ceratuff is cost effective in the long run in various application, minimises – down time, maintenance, product cost, maximises – productivity, performance and profit.
