Spiral chute dry type 1. Overview: Gravity separation is widely used in the beneficiation of metal and non-ferrous metals due to its low pollution and low cost. Spiral chute is one of the gravity beneficiation machines, characterized by a cubic parabolic cross-section, suitable for processing finer particle sizes of -0.2 millimeters. During the sorting process, there is no need to add water for flushing, and the end of the chute is divided into sections to select fine, medium, and tailings. 2、 Production principle: The screening device of the spiral concentrator is not limited to being placed on the cross (or tripod) of the support table. The average ore slurry is slowly fed to the surface of the rotating groove through the feeding groove installed at the end of the spiral groove head for sorting. The tail end is equipped with a valve block type equipment cutting groove, allowing the sorted products to be divided into three (or four) categories radially according to grade. Change the selection width of each device by adjusting the position of the valve block. The product gathering bucket is a concentric circular tube that gathers and exports the obtained variable mineral flows. The transverse plane of the spiral chute and the slope of the curve vary greatly, making it suitable for the separation of small particle mineral materials. Spiral chute dry type 3. Features 1. Stable sorting process and easy control 2. Large allowable range of ore concentration variation 3. High enrichment and high recovery rate 4. Small land occupation and water consumption 5. Simple structure, no power required 6. Large processing output 7. Simple installation and operation 8. Low investment and quick effect Spiral chute dry type 4. Spiral chute composed of feeding homogenizer, feeding chute The rotating groove, product cutting groove, equipment gathering bucket, and this groove bracket (including a cross or tripod) are composed of six parts. The spiral groove connected by the rotating plate is a key accessory. The spiral plate is made of fiberglass (fiberglass reinforced with coal gangue) and connected together by bolts. The sorting surface of the rotating groove has a pre made wear-resistant layer. It has the advantages of lightweight, sturdy, and long-lasting consumer goods that are not easily damaged. The spiral groove is equipped with a multi tube feeding homogenizer for ore dressing, which is easy to operate. There is no need to restrict the stacking of mineral sievers on the cross (or tripod) of the support table. The evenly distributed mineral mortar is slowly fed to the surface of the spiral groove through the feeding groove at the beginning of the rotating groove, and then selected for operation. The bottom of the rotating groove is equipped with a valve block type new product selection groove, which allows the sorting equipment to be divided into three categories (or four types) of new products according to grade along the radial direction. Change the acquisition width of each new product by adjusting the position of the valve block. The new product gathering bucket is a concentric circular tube that collects and exports the intercepted variable mineral flows. The cross section and slope of the curve of the fiberglass chute are very suitable for the selection of fine particle materials. Spiral chute dry type 5. Purpose 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. spiral chute dry type
