The sorting equipment for particle size 0.3 - 0.02 mm thin material of iron ore, ilmenite, chromite, pyrite, zircon, rutile, monazite, phosphate ore B, tungsten ore, tin, tantalum ore, niobium ore, as well as differences in the proportion of other non-ferrous metals, rare metals and non-metallic mineral body. The process of sorting equipment stable, easy to control, to allow changes in mineral concentration range, high concentration, high recovery rate, small footprint, less water consumption, simple structure, no power to deal with large, easy to install, easy to operate, such as low investment and quick results
Advantages.

The use of methods and principles of:

Spiral chute will be erected, calibration of vertical lines, with wood formwork or fixed in a suitable location, from sand to sand the top to screw on the two feed adding supplementary water, adjusting the concentration of ore oar, paddle mine natural swirl down from high in the rotation velocity of the slope to create a centrifugal force of inertia to the proportion of ore, particle size, shape differences, through the swirl of the role of gravity and centrifugal force will separate the ore and sand, fine ore concentrate bucket inflow then piped out into the tailings tailings sand bucket pool received by pipeline, and then drain away sand and completed the whole process of dressing.
