Working Principle

By means of unbalance hammer installed along the motor shaft, DY series three dimensional vibrating screens convert the rotation of the motor into a 3-D movement, horizontal, vertical and inclined movement, and then the 3-D movement is transferred to the screen surface, which leads to an involutes movement of the materials on the screen surface. That's why it is also called the rotary vibrating screen. Rotary vibrating screen can handle the material into the precision screening or probability screening by adjust the upper and lower ends of the phase angle of the hammer so as to change the movement trajectories of materials on the screen surface. It has the feature of long trajectory of materials and high utilization rate of screen surface.

FAQ : 

1. How to select a suitable vibrating screen?

A. what's the material and its density?

B. what's the mesh size? And which size of powder do you need?

C. What's the percentage of every size in your material?

D. What's your excepted capacity?

2. How can we handle the problem of blocking mesh ?

Except the ultrasonic vibrating screen adopts ultrasonic cleaning system, other vibrating screen adopts bouncing ball and PU ring below every deck to cleaning screen surface.

3. How about the sealing of this machine ?

Between two decks, there are silica gel ring to seal. Then the clamp would lock two decks tightly with the extended copper nut.
