Gold Mining Spiral Classifier for Gravity Concentration And Mineral Washing
Introduction:
Spiral Classifier is widely used to control material size from Ball Mill in the beneficiation process, separate mineral sand and fine mud in the gravity concentration, and clean mud and water in washing mineral process.
Features:
1. Simple structure, stable operation, safe and reliable;
2. The main screw frame electric lifting device of the standard configuration, making the equipment operation and replacement of spare parts more easy.
3. Optimization design of the helical blade, making sure of spare parts to minimize loss.
Structure:
The spiral classifier consists of cell body (Frame), speed reducer (Gear Box), motor, central shaft & Screw, spiral scatters, Weir & support parts. This machine is mainly combined with ball mill during working.
The water tank of this gold mining spiral classifier is installed obliquely. The angle of inclination is determined according to equipment configuration of equipment in the process flow. The 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. The spirals rotating at a low speed play a certain stirring role. After the slurry is stirred, the light and fine particles float above the surface and overflow from the overflow edge. Then they flow into the next working procedure of ore dressing. The heavy and thick particles sink into the bottom of the water tank and become return sand which is transported by the spirals to the ore discharge mouth for discharge. The spiral classifier normally forms closed-circuit operation together with ball mill.
