The new spiral chute 1 introduces the chute beneficiation process, including inclined flow separation. The slurry is fed to a inclined groove or inclined surface, and with the assistance of flowing water, the mineral particle group is not tightly fastened and layered. The lighter minerals in the upper layer are quickly discharged to the outside of the groove, while the heavy ore materials in the lower part stagnate in the inner groove or flow out at a slow speed from the lower part. After being collected separately, the concentrate and tailings can be obtained. Glass fiber reinforced plastic chutes are machinery for mining and beneficiation, especially ideal for sand mining and beneficiation in bays, riverbanks, sandbanks, and streams. The product has the characteristics of reasonable structure, simple installation, small footprint, simple operation, stable beneficiation, clear separation of ore, large processing output, high efficiency, high beneficiation enrichment ratio, high recovery rate, and reliable operation. It has the advantages of light weight, moisture prevention, rust prevention, corrosion prevention, and strong applicability to fluctuations in feed volume, density, Granularity, and grade. 2、 The use method is to erect the glass fiber reinforced plastic spiral chute, calibrate the vertical line, fix it in an appropriate position with an iron frame or wood, send the ore sand to the two ore feeding ports above the spiral by the sand pump, mix in the make-up water, and adjust the concentration of the ore slurry. The ore slurry naturally swirls from high to low, generating a single coherent centrifugal force in the flow speed of the revolving inclined surface, so as to obtain the difference in the specific gravity, Granularity and state of the placer, Through the effect of gravity and centrifugal force obtained through swirling flow, the sand ore is separated, and the concentrate flows into the beneficiation hopper and is connected out through pipelines. The tailings are discharged into the tailings hopper and connected to the sand pit through pipelines, and then discharged by a slurry pump, completing the entire beneficiation process. New spiral chute III. Features and highlights: 1. Large scale, high output, and the objective conditions for contemporary ore processing are to use scale effects to create benefits. 2. Fine granulation refers to the treatment of fine-grained minerals, especially for mineral materials with a particle size of -0.047mm. Originally, the machine could generally ensure the recovery of a particle size of+0.047mm. 3. With the development of Hydraulics, two-phase flow, equipment vibration, etc., GRP chutes have developed from simple use of gravity and water flow blocking force to composite and applicable centrifugal force, machine vibration force, magnetic separation force, etc. By using a composite force field, the enrichment of applicable minerals or the separation of fine or micro particles can be increased, thereby improving the recovery rate of mineral materials. 4. Based on energy conservation, environmental protection and consumption reduction, the area and space occupied should be small, and the water and electricity consumption should be small. 5. Simple and flexible operation, stable sorting steps, simple structure, convenient for Computerized maintenance management system. New type spiral chute 4. Structural composition: The spiral chute is composed of six parts: a feeding homogenizer, a feeding chute, a rotating chute, an equipment selection chute, a product gathering hopper, and a support bracket (including a cross or triangular frame). The spiral groove formed by connecting rotating discs is a key accessory. The spiral plate is made of fiberglass (fiberglass reinforced coal gangue), and a wear-resistant layer is pre made on the sorting surface of the rotating groove through bolts. It also has the advantages of lightweight, sturdy, and long-lasting consumer goods. The spiral groove is equipped with a multi tube feeding homogenizer for ore dressing, which is easy to operate. The mineral sorting device is freely placed on the cross (or tripod) of the support table. The evenly divided mineral mortar is slowly fed onto the spiral groove surface through the feeding groove installed at the beginning of the rotating groove for selection. The bottom of the rotating groove is equipped with a valve block type new product acquisition groove, which allows the sorted new products to be divided into three categories (or four categories) of new equipment along the radial direction according to grade. Change the cutting width of each new product by adjusting the orientation of the valve block. The new product gathering bucket is a concentric circular tube that gathers and exports the selected variable mineral flows. The cross section and slope of the curve of the fiberglass chute are particularly suitable for the selection of fine particle materials. New spiral chute V. Application This equipment is suitable for separating iron, ferrotitanium, ferrochrome, ferrosulfide, zircon, Rutile, monazite, phosphoethylene, tungsten sand, tin ore, tantalum, niobium ore and other nonferrous metals, rare minerals, gold and this nonferrous metal mineral with gravity difference from fine materials with Granularity of 0.3-0.02mm.
