Grain Separator
RHEduox®

Two unbalanced motors with different numbers of poles generate a double-frequency vibration for precise screening.

At the inlet side, a large vibration amplitude ensures that the material is disaggregated and transported away. Then, on the discharge side, a smaller vibration amplitude with higher acceleration is used to classify even difficult-to-screen products with high separation accuracy.

Advantages of the RHEduox® grain separator

  • 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
  • Flexible flange and collar seals at the inlet and outlet enable a dust-free operation
  • Compact design
  • Drives are easily accessible
  • Resistant to high temperatures of the screening material (up to 450 °C/ 842°F)
  • By changing the direction of rotation, the transportation speed of the screening material can be influenced systematically
