ANDRITZ SEPARATION - Screen scroll centrifuge AH

The screen scroll centrifuges AH are horizontal scroll/screen driers. Material to be dewatered is fed to the small end of a revolving, cone-shaped screen basket. Solids retained on the screen are transported out of the basket due to the angle of inclination and the wiping action of a scroll rotating at a differential speed.

With this wiping action, there is no substantial off-center movement as a result of uneven distribution of the material in the basket. An exactly predetermined bed of feed material can be left on the screen to act as filter medium in order to enhance recovery and extend screen life because of the horizontal design of the centrifuge.
