Conveyor Brakes Braking Systems for Aggregate/Mining

Mar 23, 2020· Certain types of conveyors require fail-safe brakes for stopping. These conveyors, often used in the mining and aggregate industries, include downhill conveyors (e.g., discharge and transfer conveyors), as well as overland conveyors with downhill sections. Not having fail-safe brakes on these types of conveyors can result in catastrophic damage if power is lost.

If the measured speed becomes lower (conveyor retardation slows down) a signal is transmitted to operate the solenoid valve towards its closed position until the speed corresponds to the programmed ramp down. This increases the back pressure on the brakes and decreases the braking torque. Alternatively, if the

-DOWNHILL BELT CONVEYORS-

brake system is one of the most critical components in a downhill conveyor. The brake and its control system must always be designed to safely stop the fully loaded conveyors from full speed and under any failure condition. As is often the case in engineering design, the final choice is usually a trade off between cost, simplicity and performances.

Application note Downhill conveyors benefit from AC drives

Continuous braking of the downhill conveyor is needed to prevent excessive movement of the belt and its raw material. The level of braking needed varies depending on the amount of raw material transported. This braking control avoids unnecessary conveyor wear. Downhill conveyors also require smooth and controlled starting and stopping.
