Mine spiral chute

Introduction to Spiral Chutes in Mines 1. Chute sorting includes inclined flow sorting process. Mineral mortar is fed to a partially inclined chute or inclined surface. Under the driving force of water flow, the mineral particle group is loose and layered, and the lighter minerals in the upper layer quickly flow out of the groove. The heavier minerals in the lower part either stagnate inside the groove or are discharged from the lower part at a low speed. After obtaining the difference, concentrate and tailings are obtained. The fiberglass spiral chute is a machine for mining and beneficiation, especially ideal for sand mining on coasts, riverbanks, sandbanks, and river beds. The equipment has the characteristics of correct structure, simple installation, small land occupation, simple operation, stable beneficiation, clear screening of minerals, large processing capacity, high efficiency, high beneficiation concentration ratio, high recovery probability, and stable operation. There are also advantages such as lightweight, moisture prevention, rust prevention, corrosion resistance, and strong applicability to fluctuations in ore feed volume, concentration, particle size, and grade. 2、 Production principle: The spiral concentrator is freely placed on the cross (or tripod) of the support table. The evenly proportioned mortar is slowly fed onto the surface of the spiral groove through the feeding chute installed at the head of the rotating groove, and sorting is carried out. The tail end is equipped with a valve block type equipment cutting groove, which divides the sorted products into three (or four) categories according to grade along the radial direction. Change the acquisition width of each product by adjusting the position of the valve block. The equipment gathering bucket is a concentric circular tube that allows the selected variable ore flows to converge and export differently. The cross section and slope of the curve of the fiberglass chute are very suitable for the separation of small particle materials. Mine spiral chute 3. Characteristic spiral concentrator is particularly concerned among many gravity concentration equipment because of its low power consumption, simple structure, small floor area, simple operation, stable beneficiation, clear screening minerals, no moving accessories, convenient Computerized maintenance management system, large production capacity per area, etc. The machine has a wide and relatively flat groove surface, and the area where the slurry flows in a laminar flow is relatively large, making it more suitable for processing medium to fine (-4mm) sized ores. We have made fiberglass chutes with diameters of 400, 600, 900, and 1200MM in China, Ф The processing output of 1200mm four heads is about 4-6 tons/hour. Mine spiral chute IV. The chute can be divided into three types according to the Granularity of the processed ore materials: (1) coarse particle spiral chute. The maximum particle size of the feed is more than 2-3mm, and the maximum can be 100-200mm. (2) Sand ore chute, processing 2-3 mm Granularity mineral aggregate. (3) Slime spiral chute, feeding Granularity<0.074MM. 5、 Scope of application: FRP spiral chute is suitable for separating fine particles of iron, ferrotitanium, ferrochromium, ferrosulfide, tin, tantalum and niobium, gold, coal, monazite, Rutile, zircon, rare earth and other metal and non-metallic mineral materials with complete Density contrast.
