Vibrating Screen

1. Main Features:
This serious of Vibration Screen is circular vibration and used in quarry for stone classification, beneficiation, coal dressing, chemical industry, building materials and etc. As a classifying machine, it adopts eccentric vibration exciter and tyre coupling. It has the features of advanced structure, strong vibration, low noise, easy maintenance and long life.

2. Mechanical structure: General by the vibrator vibrating screen, screen box, supporting or suspension, transmission and other components.
A. Vibrator: Uniaxial and biaxial shaker shaker vibrator.
B. Screen box: Screen box is made up by the screen frame, screen surface and the clamping device components. And the screen frame must have sufficient rigidity.
C. Support device: Supporting devices have two kinds: Hanging and seated. Block mounting is relatively simple and installation height is low, which should generally be preferred. Shaker support device is mainly composed by the elastic element, what commonly used of which are spiral springs, plate springs and rubber springs.
D. Transmission: Vibrating screen is usually driven by V-belt, the structure of which is simple. Vibrator can choose the number of revolutions.

3. Working principles: Circular vibrating screen box moves in round or oval. Vibrating Screen uses inertial vibration exciter and it is uniaxial vibrator. The vibration source is generally that motor drives exciter. While spindle fixed on the screen box rotates, driven by the motor, eccentric body mounted on the spindle will turn with it, which generates a centrifugal inertia force, so that the screen box in free vibration can produce nearly circular track vibration.
