Spiral Chute Separator

Design of Hongxing Spiral Chute Separator

In mining industry, spiral separator is widely used in the production flow of metal processing. According to the difference in sedimentation rate of mineral particles and mud, the particle sizes of ores with 1.5mm-0.03mm are classified. Waste mud or water for ore sand can be separated from the ores. This series of density separator is also usually applied to ore washing, desliming and dehydration and so on.

Spiral Chute Separator

Our screw separators are divided into single and double screw separators. Besides, they are also divided into high weir and submerged screw graders. If the overflow edge is higher than the center line of spiral shaft and lower than the external diameter of spiral at the overflow end, the graders are high weir ones. If the overflow edge is higher than the center line of spiral shaft and also higher than the external diameter of spiral at the overflow end, the graders are submerged ones. High weir ones are usually used for the classification with particle size of below 0.2mm. Submerged ones are usually used for the classification with particle size of below 0.05mm.

Working Theory of Spiral Classifier

The spiral classifier (rotary classifier) depends on different deposition speed of solid particle due to their size and weight difference. Thin mineral particles can float in the water and flow out, and the coarse particles can filtrate the powdery materials ground by ball mill, transport the coarse materials into inlet with screw, and discharge the filtrated fine materials through overflow pipe.

Structure of Spiral Concentrator

Spiral concentrator which can also be called spiral washer is composed of transmission mechanism, (left, right) spiral water tank, lifting device, lower support, lubricating device, ore discharge valve, feed inlet, etc. The water tank of this machine is installed obliquely. The angle of inclination is determined according to equipment configuration of equipment in the process flow. The (left, right) spirals driven by the transmission mechanism rotates in the water tank. The finely grained slurry enters the water bank from the feed inlet at one side and forms one slurry precipitation zone, whose surface area and volume depends on the value of the water tank’s inclination angle and the height of overflow edge. 

Various Types of Separating Machines:

Henan Hongxing Mining Machinery Co., Ltd is a professional and the largest washing and separating machine manufacturing company in China. Our company is able produce various types of separating and washing machines such as rotary separator which is also called shaking table separation machine and drum separator which has a round drum that is able to improve the working efficiency of the machine, thus reducing the energy consumption. Other than these types of machines, the screw separation machine researched and developed by our company enjoys great popularity among the customers both at home and abroad.
