Study of automatic compensation on the braking device of Down Belt Conveyor

Abstract：The braking force decline, brakes failed and even failure arising from the wear of disk braking device for long distance, large capacity and big elevation angle Down Belt Conveyor are analysed.Brake performance and the maximum braking moment of the Down Belt Conveyor is analysed and calculated to provide references for the selection and design of the braking device.On this basis, automatic compensation device is designed for the wearing clearance of braking device of Down Belt Conveyor, The device can compensate the wearing clearance promptly and automatically, maintain constant braking force and brake shoe retreat.The problem of braking force failure and safety brake reliability is solved, the result shows that the automatic compensation device is effective and reliable.
