Coarse slime hydrocyclone plus spiral chute 1. It shows that the spiral chute is a combination of the characteristics of spiral concentrator, gravity separation spiral chute, shaking table and gold concentrator. After the relevant scientific research organized by the Ministry of Metallurgical Industry, the design, universities, concentrators and other units have passed the operation appraisal. It is recognized that the mechanical performance is excellent, the separation goal is advanced, and it has won the scientific and technological research achievement award of the Ministry of Metallurgical Industry. It is now widely used in non-ferrous and Ferrous mines. This equipment is used to separate iron ore, ilmenite, chromite, pyrite, zircon, Rutile, monazite, phosphorus, tungsten, tin, tantalum niobium, niobium and other non-ferrous metal ores, rare metals and non-metallic minerals with gravity difference from fine materials with a particle size of 0.3-0.02 mm. 2、 The mineral mortar with equal working principles is slowly fed onto the surface of the rotating groove by installing the feeding chute at the end of the spiral groove head, and then selected. The tail of the spiral groove is equipped with a valve block type equipment to select the groove, and the sorted products are divided into three types according to grade along the radial direction. By adjusting the position of the valve block to change the cutting width of each equipment, the product gathering hopper allows the obtained multi head ore flow to be collected and exported separately. The cross section and slope of the curve of the fiberglass chute are very suitable for the sorting of fine particle materials. Coarse coal slurry cyclone with spiral chute III. The characteristic fiberglass spiral chute is particularly concerned among many gravity separation machines due to its low power consumption, simple structure, small land occupation, simple operation, stable beneficiation, clear mineral separation, no moving parts, convenient maintenance and management, strong processing capacity per unit area, and other characteristics. The machinery has a wider and smoother groove surface, and the area where the mortar presents laminar flow is huge, making it more suitable for handling medium to fine (-4mm) particle sized ores. China has produced spiral concentrators with diameters of 400, 600, 900, and 1200mm, Ф The processing capacity of 1200MM four head is about 4-6 tons per hour. Coarse slime hydrocyclone plus spiral chute 4. The chute can be divided into three types according to the Granularity of processed mineral aggregate: (1) Coarse particle size chute. The maximum Granularity of feeding is above 2-3MM, and the maximum can reach 100-200mm. (2) Mineral sand chute, processing 2-3MM particle grade mineral materials. (3) Slurry chute, with a feeding particle size of less than 0.074mm. Coarse coal slurry cyclone with spiral chute 5. Applicable field: The fiberglass chute is suitable for processing 0.6-0.03mm and vein ore as well as sand ore, but it is unfavorable for separation when the mud content is high. Nowadays, it has been widely used in the processing of iron ore, tungsten, tin, tantalum niobium ore, coastal and riverside ore sands, gold mines, and so on.
