resistances to motion in mining belt conveyors

  • OEM Abrasion resistant energy saving conveyor belts

    Multiple resistances occur when the conveying belts are in motion among which the strongest resistance comes from the momentary resistance of the conveying belt passing the supporting roller. It is the most effective to reduce the resistance passing the supporting rollers so as to reduce the resistance on the conveying belt device.
