Continuous solid/liquid separation with ANDRITZ screen bowl decanter centrifuges AS

ANDRITZ screen bowl decanter centrifuges AS discharge crystalline solids over the conical section. These are transported along a cylindrical screen section, where the solids are further dewatered - combining the sedimentation and filtration stages in one machine. Where advantageous, the solids can be washed on the screen.

ANDRITZ screen bowl decanter centrifuges AS have an additional final dewatering screen for maximum dryness

Acting as two machines in one, the ANDRITZ screen bowl decanter centrifuges AS combine the clarifying benefits of the solid bowl centrifuge and add a final dewatering screen section to produce maximum dryness. It is best suited for crystalline or granular solids with free-draining characteristics and unit capacities of up to 100 t/h dry solids. For some materials, in-situ washing efficiency can meet or exceed the washing capability of pusher type centrifuges.

ANDRITZ screen bowl decanter centrifuges AS are available with bowl diameters ranging in size from 18 inches to 54 inches (450 to 1,370 millimeters), with handling capacities from one hundred pounds (45 kilograms) per hour to well over 56 tons (50 metric tons) per hour of dry solids.
