Abstract: Based on the result of analysis of the factors causing the wobbling of the plant’s dewatering centrifuge in operation, a series of countermeasures are taken, such as readjustment of size of openings of fixed medium-draining screen and installation angle of sieve bend, and optimization of water spraying system of medium-draining screen. The adoption of the measures has led to not only elimination of wobbling of the centrifuge but also improvement of its dewatering efficiency and operating safety.
