The equipment of the spiral chute includes the process of selecting inclined surface flow. The slurry is fed to a inclined chute or slope, and under the assistance of water, the mineral particle group is loose and layered. The light minerals in the upper layer are quickly discharged from the groove, while the heavy mineral materials in the lower layer stay in the groove or are discharged from the bottom at low speed. After each is connected, fine beneficiation or tailings can be obtained. Spiral chutes are equipment for mining and beneficiation, especially ideal for sand mining along coasts, rivers, sandbanks, and streams. The product has the characteristics of appropriate structure, easy installation, small footprint, easy operation, stable beneficiation, clear mineral separation, high yield, high efficiency beneficiation enrichment ratio, high recovery rate, and reliable operation. It has the advantages of small weight, moisture-proof, rust proof, not easy to corrode, and strong applicability to the fluctuation of feed volume, density, Granularity, and grade. 2、 Operating principle: The spiral concentrator does not need to be restricted to placing the mineral separator on the cross (or tripod) of the support table. The same slurry is slowly fed to the rotating groove surface through the feeding groove on the spiral groove head, and sorting is carried out. The bottom is equipped with a valve block type product selection slot, which divides the selected equipment into three types (or four types) according to grade along the radial direction. Change the cutting width of each product by adjusting the position of the valve block. The equipment gathering bucket is a concentric circular tube that allows the obtained multi-directional mineral flow to be densely drawn out. The transverse surface of the spiral chute and the slope change of the curve are extremely suitable for the selection of fine particle materials. The equipment of spiral chute III. Characteristics and advantages 1. Large scale and large processing output. In principle, the current conditions for processing mineral materials are to create profits with scale efficiency. 2. Fine granulation, for the treatment of fine particle level minerals, especially for the treatment of mineral materials with a particle size of -0.047mm, the original machine can basically ensure the recovery of+0.047mm particle size. 3. With the development of Hydraulics, two-phase flow and equipment vibration, the spiral concentrator has developed from the simple application of gravity and water resistance to the combined application of centrifugal force, mechanical vibration force, magnetic force, etc. Through a composite force field, the enrichment of useful mineral materials or the separation of fine and fine particles can increase the mineral recovery rate. 4. With energy conservation and environmental protection as the fundamental starting point, the area and space occupied should be small, and water and electricity consumption should be small. 5. Simple and flexible operation, stable sorting process, simple structure, and easy maintenance management. Equipment 4 of the spiral chute.
