Rubber is often the ideal material to resist impact and abrasion damage in minerals handling equipment. Abrasion resistance is many times that of bare mild steel and the resilience of rubber returns impact energy to the material, minimising degradation, noise and damage.
For mechanical fixing of linings MHP offers hot vulcanised steel on rubber plates which are drilled and counterbored in our workshop for bolted or stud welded fixing.
MHP Steelback is a very robust form of lining often used for quarry dump truck bodies, primary chutes etc.
Plastic linings are particularly successful in overcoming build up in hoppers and silos and reducing the likelihood of discharge problems including ratholing, core flow and product degradation. In addition they act as a wear resistant lining extending service life.
Extreme abrasion is best handled by the use of Alumina based ceramics which have a wear index second only to diamond. By this means maintenance can be reduced dramatically in some instances. For example, we have improved the maintenance schedule a 4m diameter air separator, handling crushed blast furnace slag, from five weeks to a year by the use of a special Alumina lining with tremendous savings on downtime and repair and consequent improvements in productivity and efficiency.
