RD - Disc Dryers

Our disc driers of the series RD are indirectly heated contact driers, especially designed for viscous products like

  • sewage and paper sludge,
  • grape grains, grieves,
  • fish meal, blood and chicken dung.

The heating area consists of double-walled discs which are mounted in specific intervals on a hollow shaft. Transport paddles are mounted around the discs, conveying the material in axial direction. Scrapers, installed between the discs, guarantee a continuous and intensive mixing of the product. The scrapers are available in different executions and will be chosen depending on the product to be dried.
