When the drum driven the motor runs at full speed, the feed valve
automatically opens up and the suspension liquid goes through the
feed pipe into the drum, where the liquid phase passes through the
filter gauze and the screen openings on the drum and is kicked off
by the centrifugal force and flows out of the tangential
discharging outlet, while the solid phase is retained inside the
drum. When the set time is reached, the feeding stops.
After a given period of time of separation and dehydration, the
washing valve acts and the cleaning liquid passes through the
washing pipe into the drum to wash the filter cake. Upon the
completion of washing, further separation is conducted till the
required degree of dryness of the cake is reached. Then discharging
starts: the scraper holder rotates enabling the scraper to cut into
the cake layer and the cake is scraped off and discharged from the
Model PPC/PPCS centrifuge is the filter equipment characterized
with continuous running, scraper discharging and intermittent
operation, applicable to the separation of the suspension liquid
containing medium-sized granules or fine granules (0.01mm~5mm).
It can also be used for the separating of the suspension liquid
containing short fibers (with the fiber length less than 4mm), with
the concentration of the suspension liquid being 10%~60%. With
hydraulic and electric joint control mode adopted, this series of
centrifuges are capable of high degree of automization, with such
working processes as feeding, dehydrating, washing, discharging,
etc. being operated manually or by means of PLC for full automatic
The horizontal scraper discharging centrifuge has good adaptability
to the material to be processed and thus can be widely used in such
industrial fields as chemical, light industry, food, pharmacy, etc.
for the separating of over 100 kinds of substances including
ammonia sulphate, sodium sulphate, anthracene, boric acid, starch,
pesticide, synthetic resin, sodium cyanide, potassium chloride,
sodium bicarbonate, etc.
