| Summary: | The paper presents variable speed belt conveyor system where the reference speed is changed in order
to achieve improved energy efficiency of operation. The recorded measurements show that belt tension
varies within the same limits as under constant speed operation. These results introduce a new insight
of the present state of the art in variable speed belt conveyor drives. The system is realized with
remote control from the control center on an open pit mine. The structure of the multi-motor drive
system of a single conveyor, as well as of the network-based control system distributed among belt
conveyor stations and the control center are shown. Speed control of a belt conveyor system is
organized to provide better utilization of the available material cross section on the belt and
reduced electrical energy consumption of the drive. The experimental results obtained on the
system prove that, under existing constraints, the applied algorithm has not introduced additional
stress to the belt or mechanical assemblies during acceleration and deceleration processes,
while providing higher energy efficiency of operation. |
