This document describes a non-perforated basket centrifuge, which separates solids from liquids using centrifugal force without a porous barrier. It consists of a non-perforated basket suspended on a vertical shaft that is spun by a motor. During centrifugation, the heavier solids are retained on the basket walls while the lighter liquid rises to the top and is removed via a skimming tube. It is used when deposited solids impede liquid flow more than in centrifuges with porous barriers.

CENTRIFUGE

3. NON-PERFORATED BASKET
CENTRIFUGE
Principle:-
It is an example for sedimentation centrifuge
The separation is based on the difference in
densities of solid and liquid phases without a
porous barrier

4. NON-PERFORATED BASKET
CENTRIFUGE
The NPBC contains a non perforated side wall
During centrifugation solid phase is retained
on the sides of the basket while the liquid
remains at the top
This liquid is removed with the help of a
skimming tube

5. NON-PERFORATED BASKET
CENTRIFUGE
Construction:-
Under driven non perforated basket centrifuge
consists of a basket
The basket may be made of steel or any other
suitable material
The basket is suspended on a vertical shaft and is
driven by motor using suitable power system

6. NON-PERFORATED BASKET
CENTRIFUGEWorking:-
The suspension fed continuously in to
the basket .During centrifugation solid
phase is retained on the sides of the
basket, while liquid remains on the top
The liquid is removed using a skimming tube
When suitable depth of solids deposited the
operation is stopped
Solids are then scraped off by hand or using a
scraper blade

7. NON-PERFORATED BASKET
CENTRIFUGE
Uses:-
When the deposited solids offer greater
resistance to the flow of liquid. In such cases non
perforated basket centrifuge is used
