Design and Research of Spiral Chutes for Mining

Research on the Design of Spiral Chutes for Mining: 1. Introduction: Gravity separation is widely used in the beneficiation of metal or non-ferrous metals due to its low environmental pollution and cost. The spiral beneficiation machine is one of the gravity beneficiation equipment, characterized by a cubic parabola shaped cross-section, suitable for processing finer particle sizes of -0.2 millimeters. In the beneficiation process, there is no need to add flushing water, and the fine, medium, and tailings are segmented at the tail end of the tank. 2、 Use skills to make the spiral concentrator stand up, align it with the vertical line, use an iron shelf or wood to stabilize it in a suitable position, use the sand pump to transport the ore sand to the two feeding ports on the spiral head, add make-up water, and adjust the concentration of the ore slurry. The mineral slurry naturally swirls from high to low, and an inertial centrifugal force occurs in the flow rate of the swirling inclined surface to obtain the difference in gravity, Granularity and shape of the sand ore, By achieving the efficiency of gravity or centrifugal force through swirling flow, the ore and sand are separated, and the concentrate is discharged into the beneficiation hopper and connected out through pipelines. The tailings flow into the tailings hopper and are connected to the sand pit through pipelines, and then discharged by a mortar pump, completing the entire beneficiation process. Design and research of spiral chute for mining 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. Design and research of mining spiral chute IV. According to the Granularity of ore processed, the chute can be divided into three categories: (1) Coarse grained chute, the maximum Granularity of feeding is more than 2-3 mm, and the maximum can reach 100-200 mm. (2) The ore chute is used to handle 2-3mm sized ore materials. (3) Slurry chute, with a feeding particle size less than 0.074MM. 5、 Scope of application: FRP spiral chute is applicable to the separation of fine grained iron, ferrotitanium, ferrochrome, pyrite, tin ore, tantalum niobium ore, placer gold, coal, monazite, Rutile, zircon ore, rare earth ore and other metals and non-ferrous metal minerals with full density ratio difference.
