Powder Sieve
RHEsonox®

Two counter-rotating unbalance motors generate a linear motion that transports the material on the screen. The additional direct excitation of the screen cloth prevents clogging of the screen meshes by plugged grain.

This drive-excitation combination allows difficult-to-screen material, which normally cannot be classified on linear vibrating screens, to be screened precisely and with high throughput. In the ultra-fine to fine particle range, the RHEsonox® high-efficiency screen produces significantly better separation results than a conventional vibrating screen. In addition, the operating principle enables a low overall height.

Advantages of the RHEsonox® powder sieve

  • No clogged screen meshes thanks to automatic cleaning
  • Vibration amplitudes are adjustable during operation
  • Particularly flat construction
  • Quick exchange of screen cloths without entering the machine
  • Perfect for critical separations
  • Motor inspection possible during operation
