Abstract

When transporting bulk cargo at long distances, modern high productive belt conveyors must be equipped with energy-saving conveyor belts, which can reduce the energy consumption of the belt drive by 28%, and reduce the negative impact on the environment, including with ESG principles. Formula is proposed to determine the mass of emissions of harmful substances into the atmosphere - carbon dioxide, nitrous oxide and solid particles depending on the type of fuel burned to generate electricity. The use of supporting rollers on conveyors with a shortened middle roller, as well as with lower resistance coefficients to the rotation of the rollers, allows an additional 5-7% energy savings. The issue of saving energy consumed by the belt conveyor by optimizing the control and monitoring of the belt speed, as well as the processes of starting and braking the conveyor belt, is considered. Installation of gearless drives equipped with synchronous motors at high productive belt conveyors of long length allows to increase the efficiency of the drives, as well as to eliminate the work of gearboxes, starting couplings, which significantly reduces capital and operating costs.
