Vibrating Screen Types
Screen Types Inclined Screen. Inclined screens are the most basic type of screen, fixed to an inclined frame at an angle of between 15° and 30°. The entire body of the screen vibrates on helical springs circularly with the same characteristics and material flow is supplied by gravitational acceleration.

Vibrating Feeders: How They Work and Effectiveness
— Positive conveyors are rarely used due to the high vibration transmitted to the supporting structures. A way to counter the high vibration transmitted is to use a counterweight or counter-vibrating double troughs. Next are the types of vibratory feeders according to the method of applying vibration to the trough.

Influence of Load Weight on Dynamic Response of Vibrating Screen
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 accidents such as collapse of the whole machine [1 – 3]. Therefore, it is of ...
