P2 - High performance decanter centrifuge for process industries0 pages
Application
Alfa Laval P2 decanter centrifuges are designed for slurries
that are often extremely errosive and aggressive. The P2
range provides the most cost-effective, high-performance
solution combined with the lowest power consumption and
life cycle costs available.
Design
Alfa Laval designed the P2 range of decanter centrifuges with a
focus on performance, easy access, reliability and low noise
levels.
The rotating assembly is supported on a compact welded box
beam frame with main bearings at both ends. The in-line motor is
flanged or foot-mounted on the decanter with brackets for belt
tension adjustment. The bowl is driven at the conical end by an
electric motor using a V-belt transmission.
The bowl, conveyor, casing, inlet tube, outlets and other parts
that come into contact with the process media are made of AISI
316 and Duplex stainless steel.

Operating principles
Separation takes place in a horizontal cylindrical bowl
equipped with a scroll conveyor. The product is fed into the
bowl through a stationary inlet tube and is then smoothly
accelerated in a full flow feed zone design. Centrifugal force
deposits the solids on the inner surface of the bowl.
The conveyor rotates in the same direction as the bowl, but
at a different speed, thus moving the solids towards the
conical end of the bowl. The solids leave the bowl through
the solids discharge openings into the casing.
Separation takes place throughout the entire length of the
cylindrical part of the bowl, and the clarified liquid leaves the
bowl by flowing over adjustable plate dams into the casing.
