The dressing shaker is a sorting device for selecting fine-grained and fine-grained materials with high precision. When selecting low-grade tungsten and tin ore, the enrichment is high; the sorting efficiency is generally better than other fine-grain re-election equipment. High. Mainly used for sorting tungsten, tin, tantalum, niobium, chromium, and other non-ferrous, rare and precious metal ores and metals, can also be used for sorting iron, manganese ore and coal. When selecting metal ore, the effective particle size range is 3~0.019mm, and the upper particle size can be up to 10mm when coal is selected. The following introduces you to the structural characteristics and principles of the beneficiation shaker:
All shakers are basically composed of three parts: the bed surface, the frame and the transmission mechanism. The bed surface is approximately trapezoidal or rhombic, with a slope of 1 to 5 d in the lateral direction, and is placed above the inclined to the ore tank and the water supply tank. A bed strip (commonly known as a double strip) is arranged along the longitudinal direction of the bed surface, and the height of the bed strip gradually decreases from the transmission end to the opposite side, and is extinguished along one or two oblique lines. The entire bed surface is supported by the frame (for example, the hanging bed is lifted), and the frame is equipped with a slope adjusting device. A transmission device is arranged at an end of the bed near the feeding tank, and the bed surface is driven to reciprocate asymmetric movement. This movement has a rapid return motion characteristic when the bed is advanced near the end, so-called differential motion.
The principle of the ore dressing shaker is: the raw material (pulp or industrial material) is fed into the ore tank, and the slurry is added to a concentration of about 25% to 30% of the slurry, which automatically flows to the bed surface. The ore group is loose and stratified in the bed ditch by the flushing and shaking action of the water stream. The layered upper and lower ore particles are subjected to different flow pressures of water and bed friction, and move in different directions. The upper layer of light mineral particles is pushed by the larger hydraulic force, so it moves more in the lateral oblique direction of the bed surface. The bottom side of the laterally inclined surface is then referred to as the tailings side. The heavy mineral particles at the bottom of the bed are directly driven by the differential motion of the bed surface, and the particles are fanned out along the diagonal from the feed channel. The product is discharged along the edge of the bed surface, and the discharge line is long, so the shaker can accurately produce a variety of different quality products.
