solid liquid separation decanter centrifuge 

Structures and properties

Model LW solid liquid separation decanter centrifuge is the mechanical equipment used for continuously separation the materials in the suspension with density difference, by the principle of centrifugal settling. LW series centrifuge is a kind of deposition equipment of horizontal spiral discharge, continuous operation. The basic principle is 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, enters the drum; Under the action of the centrifuge 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 under full-speed running. It enjoys such features as compact structure, continuous operation, smooth running, strong adaptability to the separation material, large handling capacity, convenient maintenance, etc.

Application

LW series solid liquid separation decanter centrifuge is applicable to the separating of the suspension containing solid-phase granules with the diameter greater than 0.005mm and with the concentration being 2-40%.

solid liquid separation decanter centrifuge has wide applications in such trades as chemical, light industry, pharmacy, food, environmental protection, etc. for example: adipic acid, alum, aluminum hydroxide, ammonium hydrogen carbonate, ammonium chloride, ammonium nitrate, ammonia sulfate, anthracene, antibiotics, barium chloride, barium carbonate, barium sulfate, benzene, 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 pillow, clay, methylcellulose, coal flotation waste, corundum, velveteen, corn embryo, starch, coconut milk, food oil, fish processing, salt cake, mirabilite, hops, pesticide, diatomite, herbicide, tartaric acid, sodium sulfate, sodium phosphate, sodium nitrate, charcoal black, etc.
