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 of single-axis vibrating screens and dual-axis vibrating screens according to the eccentric reconfiguration mode
Version. The configuration of eccentric weight is better in block eccentric type.
Sieve box
The screen box is composed of a screen frame, a screen surface and its pressing device. The screen frame is made up of side plates and beams. The screen frame must be sufficiently rigid.
Supporting device
There are two kinds of supporting devices of vibrating screen: hanging type and seat type. The seat installation is relatively simple, and the installation height is low, and it should generally be preferred. The supporting device of the vibrating screen is mainly composed of elastic elements, commonly used coil springs, leaf springs and rubber springs.
Transmissions
The vibrating screen usually adopts a V-belt transmission device, the structure of the vibrating screen is simple, and the number of revolutions of the vibrator can be arbitrarily selected, but the belt is easy to slip during operation, which may lead to the blockage of the screen hole. Vibrating screens are also directly driven by couplings. The coupling can maintain a stable number of revolutions of the vibrator, and the service life is long, but the adjustment of the number of revolutions of the vibrator is difficult.
