Spiral chute separation technology: Introduction: Gravity beneficiation is widely used in the beneficiation of metallic and non-metallic ores due to its low pollution and low cost. Fiberglass reinforced plastic chute is one of the gravity separation equipment, with a structural feature that the cross-section presents a cubic parabolic state, suitable for processing finer particle sizes of -0.2MM. During the selection process, do not add water for flushing, and divide the chute into sections at the end to select fine, medium, and tailings. 2、 The production principle is that the slurry is evenly distributed and slowly fed to the spiral groove surface through the feeding groove installed at the head of the rotating groove, and sorting is carried out. The tail end of the spiral groove is equipped with a valve block type product cutting groove, and the selected equipment is divided into three types radially according to grade. By adjusting the position of the valve block to change the acquisition width of each product, the equipment gathering bucket allows the selected variable ore flow to be separately gathered and exported. The transverse plane of the fiberglass spiral chute has different slopes, which is particularly suitable for the selection of small particle mineral materials. The spiral chute ore separation technology III. The characteristic FRP chute is particularly concerned in various gravity separation 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 and other characteristics. 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. Spiral Chute Mining Technology 4. Structural Composition: The fiberglass chute is composed of six parts: a feeding homogenizer, a feeding groove, a rotating groove, a product cutting groove, an equipment gathering hopper, and a groove support (including a cross or triangular frame). The spiral groove formed by connecting the spiral pieces is the main component. The rotating plate is made of fiberglass (fiber reinforced coal gangue) and is bolted together. The rotating groove has a durable wear-resistant layer made in advance on each side. It has the advantages of light weight, firmness, and durability, which are not easy to damage consumer goods. The head of the spiral groove is equipped with a multi tube feeding homogenizer for ore dressing and averaging, which is easy to control. The sorting machine does not need to be placed on the cross (or tripod) of the support table. The evenly divided mineral mortar is slowly fed to the spiral groove surface through the feeding groove on the rotating groove head for sorting. The tail end of the rotating groove is equipped with a valve block type new equipment selection groove, which will classify the selected new products into three (or four) new products according to grade along the radial direction. To adjust the orientation of the valve block and change the width of each new equipment, it is necessary to cut it off. The new product gathering bucket is a concentric circular tube that allows the obtained multi-directional mineral flow to be densely drawn out. The horizontal plane of the spiral concentrator and the slope change of the curve are extremely suitable for the separation of fine particle ore. 5、 Use This machine is suitable for sorting iron ore, ferrotitanium ore, chromite ore, pyrite ore, zircon ore, Rutile, monazite, phosphate ore, tungsten ore, tin, tantalum niobium, niobium with a particle size of 0.3-0.02mm and other non-ferrous metal ores, rare metals and non-metallic ore bodies with different density and specific gravity.
