Aramid conveyor belts as an alternative of steel cord rubber belts

In design of mother conveyors, emphasis should be laid upon the choice of a belt type as its reliability governs both efficiency of the conveyor and consumed power of its drive. There exists a possibility to reduce the drive power input by means of decreasing the value of the friction factor between the belt and idlers, which is achieved by using a special energysaving belt, with its bottom coating made of special rubber. Another way is using a lighter weight belt having the required tensile strength according to the calculated pull of a conveyor. This is an aramid-framed belt which possesses the same physical and mechanical characteristics as steel cord rubber belts have. The physical and mechanical characteristics of the steel cord rubber and aramid conveyor belts are studied. It is found that with the aramid belts, it is possible to equip conveyors with drive, tail and bend pulleys of smaller diameters. The comparative calculations performed for the conveyors installed at Oleniy Ruchey GOK show that with replacement of the steel cord rubber belts for the aramid belts, the energy demand of the conveyors lowers and, consequently, the atmospheric emission of carbon dioxide drops due to less coal combustion at heating and power plants.
