The use of a spiral chute: 1. Equipment overview: A gravity beneficiation machine that utilizes the continuous centrifugal force generated by the slurry in the spiral rotary motion to achieve the separation of light and heavy minerals. 2、 Working principle: The fiberglass spiral chute concentrator does not need to be restricted from being placed on the cross (or tripod) of the support table. The same mineral mortar is slowly fed onto the surface of the rotating groove through the feeding chute installed at the head of the spiral groove for sorting. A valve type equipment is installed at the tail to obtain a slot, allowing the selected products to be divided into three categories (or four categories) according to grade along the radial direction. Change the selection width of each device by adjusting the orientation of the valve block. The product gathering bucket is a concentric circular tube that differentially merges and leads out the intercepted multi-directional mineral flow. The transverse plane and slope of the curve of the spiral concentrator are particularly suitable for the separation of fine-grained materials. The use of the spiral chute III. The special spiral concentrator has attracted more attention in various gravity separation equipment due to its low power consumption, simple structure, less land occupation, simple operation, stable beneficiation, clear ore screening, no need for moving parts, convenient Computerized maintenance management system, large handling capacity per unit size and other characteristics. Machinery with wider or flatter groove surfaces and larger areas of laminar flow of ore slurry are more suitable for processing medium to fine (-4mm) ore particles. Fiberglass spiral chutes with diameters of 400, 600, 900, and 1200MM have been produced domestically, Ф The processing output of 1200mm four heads is about 4-6 tons/hour. The use of spiral chutes can be divided into three categories according to the particle size of the ore being processed: (1) Coarse grain chutes, with a maximum particle size of 2-3 millimeters or more for ore feeding and a maximum of 100-200mm. (2) The ore sand chute is used to handle 2-3 millimeter sized ore materials. (3) Slurry chute, feeding Granularity is less than 0.074MM. Application of spiral chute V. This machine is suitable for separating iron ore, Ilmenite, chromite, pyrite, zircon sand, Rutile, monazite, phosgenite, tungsten, sand tin, tantalite, tantalum niobium or other nonferrous metals, rare ore metals or nonferrous metal mineral bodies with different density and specific gravity from fine and small materials with Granularity of 0.3-0.02MM.
