Application of Spiral Chutes in Mineral Processing

The Application of Spiral Chutes in Mineral Processing 1. Introduction: Chute sorting belongs to the inclined surface flow sorting process. Mineral mortar is fed to some inclined grooves or slopes, and under the push of water, the mineral particle group is loose and layered. The upper part of the light mineral quickly flows out of the groove, while the lower layer of minerals with a larger proportion stay inside the groove or discharge from the bottom at a low speed. After obtaining the difference, the selected ore and tailings can be obtained. Spiral chutes are machines for mining and beneficiation, making them ideal for sand mining in coastal areas, riverbanks, sandbanks, and river beds. The product has the characteristics of correct structure, simple installation, small land occupation, easy operation, stable beneficiation, clear screening of ore, large production capacity, high efficiency, high beneficiation enrichment ratio, high recycling rate, and reliable operation. It has the advantages of light weight, moisture prevention, rust prevention, corrosion resistance, and strong applicability to fluctuations in feed volume or density, Granularity, and grade. 2、 The technical principle is that the slurry is evenly distributed and slowly fed onto the surface of the spiral groove through the feeding groove installed at the head of the rotating groove, and sorting is carried out. The tail end of the rotating groove is equipped with a valve block type equipment to cut the groove, and the sorted products are divided into three types according to grade along the radial direction. By adjusting the position of the valve block to change the acquisition width of each product, the equipment gathering hopper allows the selected multi-directional mineral flow to be collected and led out differently. The transverse plane of the fiberglass spiral chute has a slope change curve, which is particularly suitable for the separation of small particle materials. The Application of Spiral Chutes in Mineral Processing III. Advantages and Characteristics: 1. High efficiency, high recovery probability, and precise mineral separation; 2. No power required; 3. Lightweight, rust resistant, durable, wear-resistant, and highly corrosion-resistant; 4. Low operating costs and long service life; 5. Strong adaptability to fluctuation of feed volume, density, Granularity and grade; The frictional force on the surface of 6 diamond sand makes the beneficiation efficiency superior to other plastic surfaces. The application of spiral chute in mineral processing IV. According to the particle size of processed mineral materials, the chute can be divided into three types: (1) coarse spiral chute. The maximum Granularity of feeding material is more than 2-3mm, and the maximum can be 100-200mm. (2) Mineral sand chute, processing 2-3MM particle grade mineral aggregate. (3) The spiral chute of the ore slurry has a feeding particle size of less than 0.074 millimeters. 5、 Application This product is applicable to sorting iron, ferrotitanium, ferrochrome, ferrosulfide, zircon, Rutile, monazite, phosphate rock, wolframite, cassiterite, tantalum ore, niobium ore and other non-ferrous metal ores, rare mineral metals and non-metallic minerals with specific gravity difference.
