Analyzing Different Types of Screw Conveyor Failures
Even when a screw conveyor is subjected to an upset condition and the drive unit generates full-motor torque, there should not be a mechanical failure of any component in the screw conveyor. Once the motor reaches locked-rotor amps, the motor heaters or a circuit breaker will "kick out" and power will be immediately turned off to the motor. ...
