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 filter centrifuge. 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.
Application of Basket Centrifuge
The basket centrifuge is employed in the manufacture of cane sugar, fine chemical intermediates dewatering or dehydration, 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, vegetable dehydration, cooked food dehydration etc.
When used in chemical industry, making material of filter centrifuge can be SUS304, SUS316L or Halar linning for strong corrosion sample, filter centrifuge also can be designed for flammable and combustible sample. Filter cloths with different mesh can be choosen according to solid size.
It is not just for those sample which solid density is heavier than liquid density, also suitable for solid density is lighter than liquid.
