ABSTRACT:
A multi-application speed drop detector, for a high-speed bucket belt conveyor conveying powdery substances, that can automatically perform such functions as alarming, causing ordinary and emergency stops in accordance with the amount of speed drop of the belt conveyor from a set speed level, and eliminating the effect of an increased bucket pitch at a joint in the belt. A bucket passage detection signal produced by an electromagnetic induction sensor is used in order to avoid the ignition and explosion of the powdery substance being conveyed due to a slip of the belt.
