Conveyor speed the development and use of

From the initial proven reserves of coal, coal occurrence gentle sloping incline to the main case. Directly along the seam down the incline conveyor arranged transport is the

best option, not only conducive to coal mining, and can greatly reduce the amount of roadway engineering and construction cycle, shorten transport distance, saving equipment

investment and operating costs, there are significant economic benefits.

Where the relative horizontal tilt downward transport conveyor, herein collectively referred to as the downward belt conveyor. Downward belt conveyor is running, when the motor material handling conveyor

actual speed exceeds the synchronous speed when they enter the regenerative braking power state, this time, when the conveyor decline suffered by the load force generated by the

motor with various obstacles and the braking force equilibrium, the belt will be at the stable operation of regenerative braking power status, continue to increase if the belt

speed, belt conveyor will enter coaster state. At this point if not limit or stop, there will be significant mechanical and personal accident. So how about the next belt pallet conveyor

conveyor belt speed the implementation of effective control is to avoid coaster conditions, normal safe operation of the key.
