Disc Stack Centrifuges
Most industrial processes need separation of liquids from each
other or liquids from solids. Valutech offers a complete range of
separation equipment from Alfa Laval, including their disc stack
centrifuges which separate solids and one or two liquid phases
from each other in a continuous process. The need to separate different
liquid phases and solids from each other is part of practically
every industrial process. Alfa Laval has more than one hundred and
twenty years of experience in meeting this requirement using either
decanter or disc stack centrifuge technology, and our products perform
this crucial function exceptionally well.
These centrifuges are extremely suitable for a large range of applications
involving lower solids concentrations and smaller particle and droplet
sizes. For special applications where three phases, with minimum
density differences are to be separated, disc stack centrifuges
are ideal.
 Working
Principle:
A disc stack centrifuge separates solids and one or two liquid phases
from each other in a continuous process. The denser solids are forced
outwards by centrifugal forces while the less dense liquid phases
form inner concentric layers. By inserting special plates (disc
stack) where the liquid phases meet, maximum separation efficiency
is ensured. The solids can be removed manually, intermittently or
continuously depending on the specific application. The clarified
liquids overflow in the outlet area on top of the bowl into separate
chambers sealed off from each other to prevent cross contamination.
What's SPECIAL about our centrifuges?
Our centrifuges meet the challenges posed by highly corrosive environment
and the extreme stresses that result due to operating forces of
more than 10,0000 G. We use special stainless steel materials. The
centrifuge bowls parts are die forged and weld free. We also cater
to processing liquids with highly abrasive particles. Maximum strength,
reliability and prolonged service life are ensured to meet all process
challenges.
