The process of Filtration is similar to other types
of centrifuges, the difference being in the method of unloading the Solids.
The centrifuged solids are scrapped through a scrapper operated either
manually, pneumatically or through hydraulic cylinder and the solids are
discharged through openings provided in the Basket bottom and Bottom Base /
Inertia Plate while the basket is rotating at a slow speed. The centrifuge
is driven at 3 speeds i.e. the feed speed, centrifuging feed and scrapping
speed (around 60 rpm) The drive motor is controlled by variable AC inverter
drive to vary basket speed with built in dynamic braking system. The AC
drive is incorporated with microcomputer and has a facility to interface
with programmable logic controller(PLC) for complete automation.
