This kind of centrifuge is used for continuously separating the materials with suspension and density difference. The drum and the spiral feeder rotate in the same direction but with a certain speed difference, the material is led into the feeding spiral inner cylinder via the feeding pipe and after speeding up, it enters the drum, under the action of the centrifugal force field, the relatively heavier solid-phase material deposits on the drum wall forming the residue layer. The solid-phase residue is continuously pushed by the spiral feeder to the conic end of the drum and after dehydration in the drying area, is discharged out of the machine. The machine is capable of continuous feeding, separating, dehydrating and discharging under full-speed running. It is of compact structure, continuous operation, smooth running, strong adaptability to the separation material, large handling capacity, convenient maintenance etc.. It is applicable to the separating of the suspension with the diameter of the granule of solid-phase material greater than 0.005mm and with the concentration ranging from 2% to 40%. It is widely applications in chemical, light industry, pharmacy, food, environmental protection etc. such as adipic acid, alum, aluminium hydroxide, ammonium hydrogen carbonate, ammonium chloride, ammonium nitrate, ammonia sulfate, anthracence, antibiotics, barium chloride, barium carbonate, arium sulfate, enzene, benzene carbonic acid, blood products, blue vitriol, borax, boric acid, pot ale, calcium carbonate, calcium citrate, calcium hydroxide, calcium nitrate, calcium oxalate, casein, fiber, chrome yellow, clay, methylcellulose, coal flotation waste, corundum, velveteen, corn embryo, starch, coconut milk, food oil, fish processing, salt cake, glutamic acid, hops, pesticide, diatomile, herbicide, tartaric acid, sodium sulfate, sodium phosphate, sodium nitrate, urnt ore, charcoal black etc..
