SGN deep-cone thickener, also called paste thickener, mainly consisting of deep-cone, feeding device, stirring device, control box, chemicals feeder and automatic control system; pulp density will first enter degassing drum for treatment before entering spiral-flow feeding box, and pulp density flocculated by feeding drum will enter the concentrated phase settled layer. With the re-flocculation, filtration and compression of concentrated phase settled layer, the purified overflow water will be discharged from the upper overflow weir, and underflow of high-concentration will be discharged at the cone bottom. It is mainly used in concentration and sediment of feed pulp of black water, metal ore-dressing water, power and chemical industry, for purpose of dewatering.
2. Main features:
A. Big processing capacity and good concentration effect. This equipment can achieve a tailings concentration of up to 40%～70% after concentrating tailings of metal mines, with suspended substance in the overflow less than 500×10-6.
B. Compared with a common thickener widely adopted by mineral processing plant, this equipment is remarkably featured with a big height in appearance, of which, aspect ratio is normally at 1.5～2; it is difficult for forming into large scale.
C. It requires a small floor space, small investment, low power consumption and running cost and convenient management.
D. Plastic sloping plate can be installed inside the equipment, increasing effective sediment area and concentration efficiency as well.
