Vibrating screen is generally composed of vibrator, screen box, support or suspension device, transmission device and other parts.
Vibrator
There are generally two types of vibrators for single-shaft vibrating screen and double-shaft vibrating screen according to the eccentric reconfiguration mode
Type. The block eccentric type is better for eccentric weight configuration.
The screen box is composed of a screen frame, a screen surface and a pressing device. The screen frame is composed of side plates and beams. The screen frame must be sufficiently rigid.
Support device
The supporting device of the vibrating screen has two types: hanging type and seat type. The seat type installation is relatively simple, and the installation height is low, generally should be preferred. The supporting device of the vibrating screen is mainly composed of elastic elements, commonly used coil springs, plate springs and rubber springs.
transmission
The vibrating screen usually adopts a V-belt transmission device. The structure of the vibrating screen is simple. The number of revolutions of the vibrator can be selected arbitrarily, but the belt is easy to slip during operation, which may cause the screen hole to block. Vibrating screens are also directly driven by couplings. The coupling can maintain a stable number of revolutions of the vibrator and has a long service life, but it is difficult to adjust the number of revolutions of the vibrator.
