CAD spiral chute 1 describes that gravity separation is widely used in the beneficiation of metal and non-ferrous metals due to its low environmental pollution and low cost. The fiberglass spiral chute is a type of gravity beneficiation machinery, with a cubic parabolic shape in the cross-section. It is suitable for handling finer particle levels of -0.2 millimeters. During the beneficiation process, there is no need to add water for flushing, and the tail of the chute is divided into sections to obtain fine, medium, and tailings. 2、 Technical principle: The fiberglass spiral chute separator can be freely placed on a cross (or tripod) on a support table. Equal slurry is slowly fed onto the surface of the rotating groove through the feeding chute installed at the head of the spiral groove, and sorting is carried out. The tail is equipped with a valve type product selection slot, which divides the selected equipment into three (or four) categories according to grade along the radial direction. Change the cutting width of each product by adjusting the orientation 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 cross-section of the spiral chute and the slope change of the curve are particularly suitable for the separation of fine particle materials. CAD spiral chute III. The characteristics of FRP chute are particularly concerned in various gravity concentration equipment because of its low power consumption, simple structure, less land occupation, simple operation, stable beneficiation, clear beneficiation, no need for moving accessories, convenient Computerized maintenance management system, large production per unit size, etc. The machinery has a wide or relatively flat groove surface, and the mortar presents a large laminar flow area, which is more suitable for processing medium to fine (-4MM) particle size ores. We in China have made spiral concentrators with diameters of 400, 600, 900, and 1200mm, Ф The production capacity of 1200mm four heads is about 4-6 tons/hour. cad spiral chute 4. According to the size of processed ore, the chute can be divided into three types: (1) coarse spiral chute. The maximum Granularity of ore feeding is more than 2-3 mm, and the maximum can reach 100-200 mm. (2) The sand ore chute is used to handle 2-3MM particle grade ore materials. (3) Slurry chute, feeding particle size less than 0.074 millimeters. CAD spiral chute V. This machine is applicable to the separation of fine materials with Granularity of 0.3-0.02mm to obtain iron ore, ferrotitanium ore, chromite ore, pyrite ore, zircon sand, Rutile ore, monazite ore, phosphorus, tungsten sand, tin placer, tantalum niobium, niobium ore or other non-ferrous metal ores, rare metals and non-ferrous metal minerals with different density and specific gravity.
