Microbead Coat For Screw Flight

Hofmann Microbead Coat is trowel-able mass formulated with proprietary materials of sapphire hard high alumina beads of specific size and silicon carbide doped in resin matrix with reinforcement. This is a protective coating providing a surface resistance to abrasion and chemical attack. Microbead is an excellent remedy for the preventive maintenance of any plant where erosion and corrosion are chronic problems. Microbead is widely used in cement plants, mineral processing plants for protecting screw flight where previously hard facing was carried out. It enhances the life of the flight by more than 5-8 times and thus efficiency of the conveying material improves as compare to earlier method. Microbead consists of sapphire hard beads of 90% alumina having a bead hardness of 9 on MOH scale. It can be applied on any surface like metal, ceramic, plastic, concrete, etc., to convert the soft surface to sapphire hard, chemical and corrosion resistant. It is very easy for application, room temperature application – any semi skilled person can carry out job without much effort. Salient features: Microbead is most ideal coating where high wear reduces production and increases cost in component like classifier, coal exhauster, launder and feed chute, ID fans casing, impeller, slurry pump, sand pump, cyclone, mud pump, coal and ash handling parts, screw conveyor for cement, clinker, etc; and paper, cement and mineral processing industries spares where erosion is a major problem. Advantages: increase equipment life; reduce operating cost; easily convert soft surface to hard surface; save down time; can be cast and moulded; and outperforms any other wears coating.
