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. TYPICAL BOTTOM DISCHARGE CYCLE:   Feeding : A filter media is fixed to the cylindrical surface of a perforated basket. The feed slurry is directed to the basket wall using a feed pipe. Feeding is carried out while the basket is rotating at an appropriate speed. After the required cake is built, feeding is stopped. The centrifuge is run for some time to partially de-water the solids. Feeding can be repeated if there is adequate space for further build up of cake. Washing : After feeding, washing is carried out by pumping wash liquid through the wash pipe. Spinning : The basket is run at the spinning speed to complete the de-watering process. Scraping : The speed of the basket is reduced to the scraping speed (slow speed). A scraper knife cuts the solids, discharging them through the chute. Heel Removal - Optional : Some material remains on the filter media after scraping and is called residual heel. This heel can be removed by using the heel removal system. Cleaning In Place - Optional : The centrifuge can be cleaned using a CIP system. Dynamic Braking :The centrifuge basket is braked or slowed down using an electrical braking system. The back EMF generated by the motor when idling is used to create the breaking impulse. This braking ensures a safe and friction free means of halting the rotating assembly.Seperate heat sinks are given to ensure that the heat generated is dissipated effectively and the unit can be located even outdoors. Advantages: Cake Discharge in powder form. Solid discharge in closed environment Operation can be automated using a PLC. Heel Removal System enables regenerating of filter media. Toxic, allergic or hazardous material can be safely handled. Minimum attrition of crystal due to scraping at low speeds. No contact between product and operator during operation. Drastic reduction in manual labour due to discharge of filter cake with help of a scraper. Material of construction : Stainless Steel , Carbon Steel, Hastelloy, Rubber Lined , Fluoro Polymer Coating / Lining viz.- Halar (ECTFE), Teflon (PFA ) Lining/ Coating can be provided not only on the contact parts but also on the exterior body for prevention from spillage and corrosive atmosphere.
