The reserve rate of spiral chutes is 1. Describe that the beneficiation chute includes a slope flow separation process. The slurry is fed to a inclined chute or inclined plane, and under the push of water, the mineral particle group becomes loose and layered. The upper layer of light mineral material is quickly discharged from the groove, while the lower layer of heavy mineral stays in the groove or flows out at low speed from the bottom. After obtaining the concentrate and tailings, respectively. Glass fiber reinforced plastic chutes are mining and beneficiation equipment, especially ideal for mineral mining and beneficiation on beaches, riverbanks, sandbanks, and river beds. The equipment has the characteristics of appropriate structure, simple installation, small footprint, simple operation, stable beneficiation, clear separation of ore, strong processing ability, high efficiency, high enrichment ratio, high recovery probability, and stable operation. And it has advantages such as light weight, moisture prevention, rust prevention, strong corrosion resistance, and strong applicability to fluctuations in ore feed volume, concentration, particle size, and grade. 2、 The production principle is that the slurry is evenly distributed and slowly fed onto the surface of the spiral groove through the feeding chute installed on the rotating groove head, implementing sorting. The bottom of the rotating groove is equipped with a valve block type product selection groove, which divides the selection equipment into three types according to grade along the radial direction. By adjusting the position of the valve block to change the cutting width of each product, the equipment gathering hopper allows for the differentiation and aggregation of the obtained variable mineral flow. The cross-section of the spiral chute and the slope change of the curve are very suitable for the selection of fine particle materials. The reserve rate of spiral chute is III. Special features This product is suitable for sorting iron ore, ferrotitanium ore, chromite ore, pyrite ore, zircon ore, Rutile, monazite, phosphorus ethylene, tungsten ore, sand tin, tantalum, niobium ore and other non-ferrous metal, rare metal and non-metallic ore bodies with density and specific gravity difference of 0.3-0.02MM fine materials. This equipment also has advantages such as stable and easy operation in the selection process, a wide range of allowable changes in feed density, high enrichment ratio, high recovery rate, small footprint, low water consumption, simple structure, no need for power, strong processing ability, easy installation and operation, low investment, and quick effectiveness. The reserve rate of the spiral chute is four. The structure of the fiberglass spiral chute is composed of six parts: a feeding homogenizer, a feeding chute, a rotating chute, a product selection chute, an equipment gathering hopper, and a groove bracket (including a cross or triangular frame). The spiral groove formed by the connection of spiral plates is a key component. The rotating plate is made of fiberglass (fiberglass reinforced coal gangue) and connected together by bolts. The rotating groove has a pre designed durable and wear-resistant layer on the selected surface. She has the advantages of lightweight, solid, and durable use of consumer goods. The spiral groove is equipped with a multi tube feeding homogenizer above it to screen the ore, which is also easy to operate. The concentrator is not limited to being placed on a cross (or tripod) on a support table. The evenly distributed mineral mortar is slowly fed onto the surface of the spiral groove through the feeding chute installed at the head of the rotating groove, and sorting is carried out. The bottom of the rotating groove is installed in a valve block type new equipment cutting groove, allowing other new products to be selected and classified into three (or four) categories according to grade along the radial direction. Change the acquisition width of each new product by adjusting the position of the valve block. The new equipment gathering bucket is a concentric circular tube that converges and leads out the intercepted multi-directional mineral flow. The transverse section of the spiral chute has a slope change, which is particularly suitable for the sorting of fine-grained materials. Spare rate of spiral chute 5. This machine is suitable for sorting iron, ferrotitanium, ferrochrome, ferrosulfide, zircon, Rutile, monazite, phosphate rock, tungsten ore, placer tin ore, tantalum niobium ore, tantalum niobium ore and other non-ferrous metals, rare ore metals and non-metallic ore bodies with gravity difference. spiral chute reserve rate
