Multi stage spiral chute 1. It indicates that the chute selection includes the process of inclined surface flow selection. The slurry is fed to a inclined chute or slope, and under the assistance of water, the mineral particle group is loose and layered. The light minerals in the upper layer are quickly discharged from the groove, while the heavy mineral materials in the lower layer stay in the groove or are discharged from the bottom at low speed. After each is connected, fine beneficiation or tailings can be obtained. Spiral chutes are equipment for mining and beneficiation, especially ideal for sand mining along coasts, rivers, sandbanks, and streams. The product has the characteristics of appropriate structure, easy installation, small footprint, easy operation, stable beneficiation, clear mineral separation, high yield, high efficiency beneficiation enrichment ratio, high recovery rate, and reliable operation. It has the advantages of small weight, moisture-proof, rust proof, not easy to corrode, and strong applicability to the fluctuation of feed volume, density, Granularity, and grade. 2、 The production principle is that the evenly proportioned mortar is slowly fed onto the rotating groove surface by the feeding groove at the beginning of the spiral groove, and is selected. The tail end of the spiral groove is equipped with a valve block type equipment to cut the groove, allowing the sorted products to be divided into three types according to grade along the radial direction. By adjusting the orientation of the valve block to change the selection width of each equipment, the product gathering hopper will merge and export the obtained multi head ore flow differently. The transverse plane and curve slope of the fiberglass spiral chute are different, especially suitable for the selection of small particle materials. Multi stage spiral chute III. Advantages and characteristics: 1. High efficiency, high recovery rate, and accurate ore sorting; 2. No power required; 3. Lightweight, rust proof, durable, wear-resistant, and corrosion-resistant; 4. Low cost operation, long service life; 5. It is applicable to the fluctuation of feed volume, density, Granularity and grade; The frictional force formed on the surface of 6 diamond sand makes the beneficiation efficiency better than other plastic surfaces. Multi section Spiral Chute 4. Construction Composition: The fiberglass spiral chute is composed of six parts: a feeding homogenizer, a feeding chute, a spiral chute, an equipment acquisition chute, a product gathering hopper, and a support bracket (including a cross or triangular frame). The rotating groove connected by the rotating disc is the main accessory. The spiral plate is made of fiberglass (fiberglass reinforced coal gangue) and is bolted together. The spiral groove has a pre made durable wear-resistant layer on the selected surface. She has the advantages of lightweight, strong, and durable consumables. The head of the rotating groove is equipped with a multi tube ore feeding homogenizer to divide the ore dressing evenly, and the control is not cumbersome. The mineral sorting machine is freely stacked on a cross (or tripod) on a supporting table. The evenly divided slurry is slowly fed to the rotating groove surface through the feeding groove installed at the end of the spiral groove head, and sorting is carried out. The tail end of the spiral groove is installed in a valve block type new product selection groove, and the selected new products are divided into three (or four) types 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 allows the diverse mineral flows obtained to converge and export differently. The transverse plane and slope of the spiral chute are very suitable for selecting small particle materials. Multi section spiral chute V. This machine is used to separate 0.3-0.02mm fine materials to obtain iron, ferrotitanium, ferrochrome, ferrosulfur, zircon ore, Rutile ore, monazite ore, phosphorus, wolframite, tin ore, tantalum niobium, niobium ore and other non-ferrous metal ores, rare mineral metals and non-metallic minerals with gravity differences.
