Nozzle separators are continuously operating disk centrifuges. They are built as centrifugal clarifiers and separators and are more solids-orientated than self-cleaning separators. When they are configured to function as clarifiers, they are called concentrators. They are used to thicken solids from suspensions.
As with disk separators with solid-wall bowl, the disk separators with self-cleaning bowl are equipped with a stack of conical disks to create a large equivalent clarification area within a relatively small bowl volume. These separators are likewise available as versions for clarification and separation.
Pusher centrifuges, also called horizontal basket centrifuges, possess filtration bowls equipped with metal screening sheets or slotted sieves. These systems also filter liquids in the centrifugal field and retain solids as filter cakes in the bowls. An oscillating pushing motion transports the cakes out of the bowls. Solids may also be washed with these systems.
Peeler centrifuges are batch centrifuges and usually possess perforated filtration bowls in which cloth filters are used. The liquid in the admitted suspension is centrifuged and filtered at high speeds during which the solids form on the cloth filter in the shape of filter cakes. Once they have been spun-dried, these filter cakes are scraped
Basket Centrifuges Have a Simple Principle The solid wall basket centrifuge uses centrifugal force to promote liquid/solid separation. The feed slurry is introduced into the rotating basket and is accelerated to the basket speed. Solids/contaminants are pulled radially away from the liquid by centrifugal force and collects along the inner wall of the basket. The
A decanter centrifuge separates solids from one or two liquid phases in one single continuous process. This is done using centrifugal forces that can be well beyond 3000 times greater than gravity.
