Abstract

The paper discusses energy-saving belts reducing energy demand of belt conveyors by 40%. The heat-resistant belts, keeping carcass of belts out of burning, allow conveying hot materials at a temperature to +399 ºС. Design features of such belts are presented. Furthermore, the authors describe design and fabricating characteristics of belts for tubular belt conveyors. The role of elasticity and strength characteristics of belts in substantiation of parameters for pressure-belt high-angle conveyors is shown. It is highlighted that modern rubber fabric and steel cord conveyor belts enable engineering of special high-capacity conveyors with low energy requirement. The information presented in the article allows drawing the following conclusions:
1. Equipment of long high-capacity conveyors (more than 1000 m long) with energy-saving belts, possessing lower viscoelastic properties of the material backing of service belt, reduces energy consumption of conveyor drive by 40%;
2. Use of heat-resistant belts in metallurgical and cement industries, which eliminate burning of carcass of belt owing to special coating rubber and heat-resistant cushion layer, allows transportation of hot materials with a temperature up to +399 ºС and, thereby, extension of application range of belt conveyors;
3. By varying longitudinal elasticity modulus of steep conveyor with pressure belt, it is possible to reduce radius of transition section of the conveyor and to avoid undesired stress and strains of the conveyor belt elements;
4. Under different longitudinal strains of load-carrying and pressure belts of steep conveyor, it is possible that pressure belt slides on loaded material, which negatively affects positioning of load on the belt due to action of friction forces and adds to wear of the load-carrying belt. This can be avoided or mitigated by selecting longitudinal elasticity moduli of load-carrying and pressure belts, which suggests availability of wide variety of the moduli.
