The working principle of a spiral chute is as follows: 1. Introduce the steps of mineral separation by the chute, which belongs to the inclined flow separation. Mineral mortar is provided on a partially inclined chute or inclined surface. With the assistance of water, the mineral particle group is not tightened and layered. The lighter mineral material on the upper part is quickly discharged to the outside of the chute, while the heavier mineral material on the lower part stays in the inner groove or flows out at a slow speed from the lower part. After being obtained separately, concentrate and tailings are obtained. The fiberglass spiral chute is an equipment for mining and beneficiation, making it ideal for mining sand mines in coastal areas, riverbanks, sandbanks, and streams. The product also has the characteristics of reasonable structure, simple installation, less land occupation, simple operability, stable beneficiation, clear screening of ore, large processing output, high efficiency, high beneficiation concentration ratio, high recovery rate, and reliable operation. It has the advantages of light weight, moisture prevention, rust prevention, corrosion prevention, and strong applicability to feed volume, density, Granularity, and grade fluctuation. 2、 The production principle is the same: the slurry is slowly fed to the rotating groove surface through the feeding chute at the head end of the spiral groove for sorting. The bottom of the spiral groove is equipped with a valve block type product acquisition groove, and the sorting equipment is divided into three types according to grade along the radial direction. Change the cutting width of each product by adjusting the orientation of the valve block, and gather the selected multi-directional mineral flow through the equipment gathering hopper. The slope change of the cross-section and curve of the fiberglass chute is very suitable for the selection of fine particle materials. The working principle of the spiral chute is 
III. Features 1. The selection process is stable and easy to operate. 2. The allowable range of feed concentration changes is relatively large. 3. The enrichment ratio is high, and the recovery probability is high. 4. The land area is small, and the water consumption is low. 5. The structure is simple and does not require power. 6. The processing output is large. 7. The installation is simple and easy to understand, and the operation is simple. 8. The working principle of the spiral chute is low investment and quick results According to the Granularity of the processed mineral materials, the chutes can be divided into three categories: (1) coarse particle spiral chutes, the maximum particle size of ore feeding is more than 2-3mm, and the maximum can be 100-200mm. (2) The sand ore chute is used to handle 2-3MM sized ores. (3) Slurry chute, feeding Granularity is less than 0.074mm. Working principle of spiral chute V. Application The scope of application of this machine is to separate iron, ferrotitanium, chromite ore, pyrite ore, zircon ore, Rutile ore, monazite ore, phosphorus, tungsten ore sand, sand tin ore, tantalum niobium, niobium ore or other non-ferrous metal ore, rare metal or non-metallic ore body with gravity difference from 0.3-0.02mm fine material.
