RT Circular Dryers

Energy-Efficient and Powerful

Since a process liquid is usually used for vibratory grinding, the workpieces are contaminated with it and should be cleaned or dried at the end of the process. Either hot air or special drying media are used to dry the components. For this purpose, the workpieces are placed in a circular container, in which there is a heated medium for drying. Nut and corn cobs are often used in rotary vibration dryers.

  • Efficient thanks to optimized heating and covers
  • Drying of components mostly in one pass
  • Universal use of different drying media
  • Spiral flat ramp
  • Protective cover and suction for dust reduction optionally available

  • Economical and fast drying of components after vibratory finishing 
  • Achievement of spotless surfaces 
  • Drying and polishing of the workpieces in one operation
  • Integrated screening section for efficient workpiece separation
  • Can be switched between batch and continuous operation using a built-in manually (optionally pneumatically) operated slide
  • Spirally rising tank bottom with ribbed bottom for gentle processing with a flat rise
  • Modular interchangeable sieve inserts and discharge chutes 
  • Possibility of connecting to dust extraction systems as standard

Application Areas

  • Component drying directly after the surface grinding process
  • Polishing of components
  • Stain reduction
  • Fine machining of particularly difficult contours
  • Prevention of flash rust due to completely dried surfaces
  • Efficient drying of complex geometries
