Analysis of the Influence of the Type of Belt on the Energy Consumption of Transport Processes in a Belt Conveyor

open access: yesEnergies, 2021
Results of tests into the energy-efficiency of belt conveyor transportation systems indicate that the energy consumption of their drive mechanisms can be limited by lowering the main resistances in the conveyor. The main component of these resistances is
