Screening efficiency impact factors
- Reject rate
- Basket type
- Slots gap
- Bar depth/angel
- Velocity
- Open area
Rotor Pulse
- Pressure pulse forces the stock through the screen
- Vacuum pulse draws disturbing components away from the screen surface, removing them from the screen area
- The higher the rotor peripheral speed, the greater the pressure pulse
- The higher the pressure, the worse the screening efficiency
Screen Basket Profile with high turbulence
- Bar angle fit for different application
- Bar angle even more important than slot gap
