PPSBDF Automatic Centrifuge adopts platform structure,with out housing welded with chassis.Adopting quick open structure,shell cover is fixed to shell body with flange hydraulic pressure is applied to open the lid,Shell cover is equipped with feeding pipe,washing pipe,sight glass viewing-light,scraper device,and man hole and so on,standard flanges are applied for the joints connected to external pipe.
1.The centrifuge adoptes whole enclosed structure with dependable seal facility which is filled with nitrogen to meet the explosion proof demand.
2. Adopted with quick open clamshell structure and the optional swash plate distributor, products can be distributed evenly to reduce vibration caused by unbalanced distribution. with additional washing function, it has a better cleaning effect.
3. The motor is set on top of the machine and directly linked to main shaft which will bring higher transmission efficiency and reduce friction powders.
4. Pneumatic assisted scraper is adopted to remove the remnant filter cake and CIP system is optional to secure clarity to be in accordance with GMP Norm.
5. Frequency control system is adopted to assure a stable start-up. PLC is adopted to ensure a complete automatic process including feeding, filtering washing and discharging etc. lt adopts dynamic(regenerative) breaking without fiction powder pollution and friction heat so it is much safer
6. No need of human supervision. Following security systems are adopted: self-monitoring and protecting system, speed inspection, product level detection, over-vibration protection, over-heat ,protection for motor, mechanical and electric double interlock for scraper rotary and movement, interlock for lid's open and machine's running.

Properties and Uses
PPSBDF centrifuges have a perfect automatic performance and a large processing capacity. In accordance with users’ demand,procedures such as feeding, separating washing, dehydrating and discharging can all be automatically finished followed by remote control. It's suitable for solid-liquid separation of fibroid products as well as suspension which contains fine grains and medium size grains solid. For example: chemical industry products such as :gypsum,ammonium sulphide,bluestone,potassium chloride, borax, dyestuff, resin,pesticide and pharmaceutical products such as:salt, monosodium glutamate, food additive, starch, sugar, flavoring, antibiotic, vitamin and other industries such as mining and environmental protection ect.
PPSBDF centrifuge is a kind of vertical centrifuge with PLC control automatic filtration type and down scraping discharging, which adopts continuously running and intermittent discharge. SG centrifuge is semi-automatic centrifuge. Driven by the motor, the drum revolves step by step to the speed suitable for feeding, then the products which is to be separated enter to the revolving drum through feeding pipe. Centrifuge would stop feeding if the products' volume amounts reach to the predetermined date and the speed raises higher for separation. Suspension's separation can be made possible by filter cloth(or filter net)under the effect of centrifugal force. Liquid phase is draught out through filter layer and thrown into the empty chamber and finally discharged from the liquid outlet while the solid phase reminds on the drum to from bucket-shaped filter cake which will be washed in the following steps. When filter cake meets the requirement of separation, centrifuge will be slowed down to the discharging speed. The scraper begins to take effect and scrape the filter cake from inner wall to the products outlet of centrifuge.
