Driven by rounding motion of vibrator, rounding vibrating screen is widely applied in quarries and mines. It has the advantages of adjustable amplitude, long dropping line, several screening decks, clear screening effect for each type of end products and high screen efficiency.

Vibrating Screen Operating Principle:
The main parts of the vibrating screen are screening case, sieve and eccentric shaft.
Driven by the motor, the eccentric shaft rotates quickly and then drives the sieve to move uniformly. The moving track of the screening case is just like a circle. While screening, the smaller materials will flow down to the lower sieve while the bigger one is left on the top sieve. Generally speaking, the materials on the top sieve will be transported back to be crusher again and the lower ones will be separated into different size's end product.
