Principle of spiral chute sorting

Principle 1 and Equipment Overview of Spiral Chute Separation: 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、 Using a method to set up a spiral concentrator, align it with the vertical line, use an iron frame or wood to fix it in a suitable position, and use a sand pump to transport the ore to the two feeding ports on the spiral head. Add supplementary water, adjust the concentration of the ore slurry, and the ore slurry will naturally swirl from top to bottom. In the flow rate of the inclined plane of the rotation, an inertial centrifugal force will occur, which will cause differences in the gravity, particle size, and shape of the sand ore, Through the influence of the gravity or centrifugal force of the swirling flow, the sand ore is separated, and the selected ore flows into the concentrate hopper and is piped out. The tailings flow into the tailings hopper and are piped to the sand ore pool, and then discharged by a slurry pump, completing the entire beneficiation process. Principle of spiral chute separation 3. Characteristics This product is suitable for separating 0.3-0.02mm fine materials to obtain iron ore, ferrotitanium ore, chromite ore, pyrite ore, zircon sand, Rutile, monazite, phengite, tungsten sand, sand tin, tantalum, tantalum niobium and other non-ferrous metal ores, rare metals and non-metallic ore bodies with different densities and specific gravity. This equipment also has stable and easy to operate selection processes, a wide range of allowable changes in feed density, high enrichment ratio, high recycling rate, small land occupation, low water consumption, simple structure, no need for power, strong processing ability, easy installation, easy operation, low investment, and quick effectiveness. The principle of spiral chute sorting is . The structure of the spiral chute consists of six parts: a feeding homogenizer, a feeding chute, a rotating chute, a product acquisition chute, an equipment gathering hopper, and a support bracket (including a cross or triangular frame). The spiral groove connected by the rotating disc is a key component. The spiral plate is made of fiberglass (fiber reinforced coal gangue), and a wear-resistant layer is pre made on the sorting surface of the rotating groove through bolts. She has the advantages of lightweight, strong, and durable consumer goods. Above the spiral groove, a multi tube feeding homogenizer is installed to evenly distribute the ore, and the operation is not complicated. The screening machine is not limited to being placed on the cross (or tripod) of the support table. The evenly distributed slurry is slowly fed onto the spiral groove surface through the feeding chute installed at the head of the rotating groove, and sorting is carried out. The tail end of the rotating groove is equipped with a valve block type new equipment to intercept the groove, allowing the sorted new products to be divided into three categories (or four categories) according to grade along the radial direction. Change the selection width of each new equipment by adjusting the position of the valve block. The new product gathering bucket is a concentric circular tube that gathers and exports various obtained mineral flows. The lateral plane of the spiral concentrator and the slope change of the curve are extremely suitable for the selection of fine-grained materials. 5、 Application: FRP spiral chute is suitable for separating fine iron, ferrotitanium, ferrochrome, ferrosulfur, sand tin, tantalum niobium, placer gold, coal, monazite, Rutile, zircon sand, rare earth and other metal and nonferrous metal minerals with completely sufficient specific gravity difference.
