Use of spiral chutes

The use of spiral chutes involves the inclined surface flow sorting process. Mortar is fed to some inclined grooves or slopes. Under the push of water flow, the mineral particle group becomes loose and layered. The upper layer of light mineral material is quickly discharged from the outside of the groove, while the lower layer of heavy mineral is retained inside the groove or slowly discharged from the bottom. After each is taken, the selected ore and tailings can be obtained. Spiral chutes use fiberglass chutes as mining and beneficiation machines, making them particularly ideal for sand mining and beneficiation on beaches, waterways, sandbanks, and streams. The equipment has the characteristics of appropriate structure, simple installation, small footprint, easy operation, stable beneficiation, clear screening of minerals, large production capacity, high efficiency, high beneficiation enrichment ratio, high recycling rate, and stable operation. And it has advantages such as light weight, moisture prevention, rust prevention, strong corrosion resistance, and strong adaptability to fluctuations in ore feed volume, concentration, particle size, and grade. 2、 Application skills: the spiral chute uses the glass fiber reinforced plastic spiral chute to set up, align with the vertical line, use the iron shelf or wood to stabilize in the appropriate position, use the sand pump to transport the mineral sand to the two ore feeding ports above the spiral, add make-up water, and adjust the concentration of the mineral slurry. The mineral slurry naturally swirls from high to low. A single coherent centrifugal force appears in the rotating slope flow rate, and the gravity, Granularity and shape of the mineral sand are different, By utilizing the gravity and centrifugal force of the swirling flow, the sand and ore are separated, and the selected ore is discharged into the concentrate hopper and connected out through pipelines. The tailings enter the tailings hopper and are connected to the sand tank through pipelines, and then discharged by a mortar pump, completing the entire process of beneficiation. spiral chute for use. 3、 The fiberglass spiral chute is particularly important in many gravity beneficiation machines due to its low power consumption, simple structure, small footprint, easy operation, stable beneficiation, clear screening of minerals, no movement accessories, easy maintenance and management, and large processing capacity per unit size. The machine has a wide and stable groove surface, and the mortar has a large laminar flow area, which is more suitable for processing medium and fine (-4mm) Granularity ores. Our country has made spiral chutes with diameters of 400, 600, 900, and 1200MM, Ф The output of 1200mm four heads is about 4-6 t/h. Spiral chutes can be classified into three categories based on the particle size of the ore being processed: (1) Coarse grained chutes, with a maximum particle size of 2-3 millimeters or more for ore feeding and up to 100-200mm. (2) Sand chute, processing 2-3MM Granularity mineral aggregate. The use principle of spiral chute: (3) spiral chute for slime, feeding Granularity<0.074mm. 5、 The fiberglass spiral chute is suitable for processing 0.6-0.03mm and vein and placer ores, but it is unfavorable for sorting when the mud content is high. It is now widely used for processing iron ore, tungsten, tin, niobium tantalum ore, coastal and river sand, and placer gold, among others. Use of spiral chute: Use of spiral chute
