How a Basket Centrifuge Works

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 clarified liquid builds up along in the inside and flows up and over the basket wall. It collects along the inside of the housing and is discharged by gravity through the outlet. Liquid clarification continues until the basket can no longer retain any solids and must be emptied. Automatic and semi-automatic solids discharge is available for suitable solids consistency.

Other Names for Basket Centrifuges

Basket centrifuges are often called centrifugal filters or clarifiers. They have a perforated wall and cylindrical tubular rotor. In many cases the outer wall of a basket centrifuge consists of a fine mesh screen or a series of screens with the finer mesh screens supported by the heavier coarse screen, which in turn is supported by the bowl. The liquid passes through the screen, and the particles too large to pass through the screen are deposited. The basket centrifuge is employed in the manufacture of cane sugar, in the home and in laundries for the rapid drying of clothes, and in the washing and drying of many kinds of crystals and fibrous materials, etc.
