Spiral chute sub item quotation 1. Introduction: The chute beneficiation includes the slope flow beneficiation process. Mineral mortar is fed to some inclined inclined grooves or slopes. With the assistance of flowing water, the mineral particle group is not tightly fastened and layered. The upper part of the light mineral material is quickly discharged to the outside of the groove, while the lower part of the heavy mineral material stagnates in the inner groove or flows out at a slow speed from the lower part. After being obtained, the selected ore and tailings can be obtained. Spiral chutes are mining and beneficiation machinery, especially ideal for sand mining along coasts, rivers, sandbanks, and streams. The product is also characterized by suitable structure, easy installation, small footprint, easy operation, stable beneficiation, clear beneficiation, large processing capacity, high efficiency, ultra-high enrichment ratio, high recovery rate, and stable operation. It has the advantages of small weight, moisture prevention, rust prevention, strong corrosion resistance, and strong applicability to the fluctuation of feed volume, density, Granularity, and grade. 2、 Technical principle: The spiral chute separator is not limited to being placed on the cross (or tripod) of the support table. Equal slurry is slowly fed to the spiral groove surface through the feeding chute at the end of the rotating groove head for sorting. The bottom is equipped with a valve block type equipment acquisition slot, allowing other products to be divided into three types (or four types) according to grade along the radial direction. Change the selection width of each device by adjusting the position of the valve block. The product gathering bucket is a concentric circular tube that collects and exports the intercepted variable mineral flows separately. The transverse surface of the fiberglass chute has a very variable slope, which is suitable for the selection of fine particle materials. Spiral chute sub item quotation III. Advantages and characteristics: 1. Stable, easy to control, with a relatively large concentration range. 2. The material has strong production and processing capabilities, high enrichment ratio, and high recycling probability. 3. Small footprint, low water consumption, simple construction, and no need for power. 4. Easy to install, easy to operate, minimal investment, and fast recovery of benefits. Subdivisional quotation for spiral chutes 4. Types: According to the particle size of the processed ore, the chutes can be divided into three categories: (1) Coarse grained spiral chutes, with a maximum particle size of 2-3 millimeters or more for ore feeding, and a maximum of 100-200mm. (2) Mineral sand chute, processing 2-3 mm particle size mineral materials. (3) Slime spiral chute, feeding Granularity<0.074MM. The spiral chute is applicable to separate iron, ferrotitanium, ferrochrome, ferrosulfide, zircon, Rutile, monazite, phosphate, tungsten, sand tin, tantalum niobium, tantalum niobium and other non-ferrous metal ores, rare metals and non-metallic ore bodies with specific gravity difference.
