Industrial screener RHEWUM DF

The drive principle of the DF is based on the use of two unbalance motors with different speeds. The motor with the lower speed and the greater amplitude is mounted on the inlet side, the one with the higher speed and the smaller amplitude on the outlet side.

At the inlet, the product is loosened and mixed by the large vibration amplitude. At the outlet, the high frequency of the motor ensures precise screening even of difficult-to-screen product due to the higher acceleration. By changing the directions of rotation, the transportation speed of the material to be screened can be specifically influenced.

Advantages of the DF industrial screener

  • At the inlet side, a large vibration amplitude ensures the disaggregation of the material
  • At the outlet, the material is sharply classified with a low vibration amplitude and high frequency
  • Static machine housing includes the screening unit allowing fixed flange connections
  • Low dynamic loads
  • Drives are easily accessible
  • Resistant to high temperatures of the screening material (up to 450 °C/ 842°F)
  • By changing the directions of rotation, the transportation speed of the screening material can be influenced systematically
