Flottweg manufacture horizontal DECANTER centrifuges for continuous
two phase separation (liquid from
solids) and three phase
separation
(2 solids and one liquid or two liquids and one solid).
Applications are as varied
as thickening and dewatering sludge, suspensions with granular
solids, clarification of liquids, classification of fine pigments,
separation of plastics and separation of organic/aqueous mixtures.
Flottweg provides a broad range of DECANTER sizes, from pilot scale
or small production up to industrial scale with capacities of 200
m³/h.
There are four types of decanter centrifuges available:
Mode of operation
The essential part of the decanter is the rotating part which
consists of a cylindrical/conical bowl with a conveyor scroll inside
which rotates at a differential speed. The rotating part is driven
by electric motors via belt transmission. Feed enters the bowl
through a central feed pipe. Through ports in the scroll body, feed
passes into the bowl where separation by
centrifugal force takes place. In a decanter, the product is
separated into a liquid phase and a solids phase. The discharge of
the separated
liquid can be under pressure or
by gravity. The separated solids are
conveyed by the scroll to the conical end of the bowl and are
discharged.
Decanters can also be configured for gas tight operation as may be
required for toxic or explosive materials.
