GKH is designed with the siphonage as similar as vacuum pipe except the functions of common peeler centrifuge. Before feeding, open backflush valve to regenerate the filter medium, and materials are evenly distributed onto filter medium on inner wall of basket by distributor in feeding. Liquid phase passes through filter medium and gaps between internal baskets under the action of centrifugal force, and enters siphon chamber through the basket and through-hole of siphon chamber and finally discharges from siphon pipe. Solid phase is retained on filter medium and forms filter cake. Stop feeding when filter cake layer reaches the set thickness. Next, open the washing valve, soak and wash the filter cake in basket, perform the secondary dewatering after washing, unload materials after dewatering materials for a certain time and fully drying them. Start scraper and solid materials will be scraped and discharged out of machine from discharge pipes, and scraper will retract and enter the next cycle after unloading materials.
