Stress Relaxation In Conveyor Belts

reduce belt stress particularly for highcapacity overland belt conveyor systems with high belt speeds the resulting thermal energy in conventional drives with nonfrequencycontrolled AC motors is of great significance in the design of motors or fluid couplings and starter resistors

We are committed to building crushing, industrial grinding, ore processing and green building materials, and provides intelligent solutions and mature supporting products.
