The screen works by the action of the excitation which usually produces periodic alternating centrifugal force by the rotation of eccentric mass. In the working process, due to the inappropriate design of the structures and the unsuitable parameter settings, the vibrating screen is prone to underload or overload conditions, which results in bad screening effect or induces fatigue cracks and even causes serious acc
