Experimental spiral chute

Experimental spiral chute 1: Introduction to gravity beneficiation, which is widely used in the beneficiation of metallic and non-metallic minerals due to its low environmental pollution and low cost. The spiral chute is one of the gravity sorting machines, with a structural characteristic of a cubic parabolic cross-section. It is used to process finer particle sizes of -0.2mm, and does not require flushing water during the sorting step. Fine, medium, and tailings are segmented at the bottom of the chute. 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 end of the rotating groove, implementing sorting. The tail of the rotating groove is equipped with a valve block type product acquisition groove, and the selected equipment is divided into three types according to grade along the radial direction. By adjusting the orientation of the valve block to change the cutting width of each product, the equipment gathering hopper allows the selected multi-directional mineral flow to be distinguished and gathered. The cross-section of the fiberglass chute and the slope change of the curve are particularly suitable for the separation of fine particle materials. Experimental Spiral Chute III. Advantages and Characteristics 1. High efficiency, high recovery probability, and precise mineral sorting; 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 experimental spiral chute IV. According to the Granularity of the ore processed, the chute can be divided into three types: (1) coarse size chute, the maximum particle size of ore feeding is more than 2-3MM, and the maximum can reach 100-200mm. (2) The ore chute is used to handle 2-3mm sized ore materials. (3) Slurry chute, feeding Granularity is less than 0.074MM. 5、 The use of fiberglass chutes in the field is suitable for processing 0.6-0.03MM and vein ores as well as minerals, but it is unfavorable for sorting when the mud content is high. It is now widely used for processing iron ore, tungsten, sand tin, tantalum niobium ore, bay and riverbed ore sand or placer gold, and so on. Experimental Spiral Chute Experimental Spiral Chute
