Spiral chute beneficiation technique 1. Introduction: Spiral chute summarizes the characteristics of gravity beneficiation spiral chute, fiberglass spiral chute, shaker, and beneficiation centrifuge. After relevant scientific research organized by the Ministry of Metallurgy, and appraisal conducted by departments such as design, school, and beneficiation company, it is recognized as having superior mechanical performance and advanced beneficiation indicators, and has won the Science and Technology Research Achievement Award from the Ministry of Metallurgy Industry. It is now in the field of non-ferrous metals Ferrous is widely used. This machine is suitable for separating iron, ferrotitanium, chromite ore, pyrite, zircon ore, Rutile, monazite, phosphate rock, tungsten sand, placer tin, tantalum niobium ore, niobium ore and other nonferrous metals, rare mineral metals and nonferrous metal ore bodies with specific gravity difference from fine materials with Granularity of 0.3-0.02mm. 2、 The working principle is that the ore slurry is slowly fed onto the rotating groove surface through the feeding chute installed at the beginning of the spiral groove, and sorting is carried out. The tail end of the spiral groove is equipped with a valve block type product acquisition groove, and the selected equipment is divided into three types according to grade along the radial direction. By adjusting the orientation of the valve block to change the cutting width of each product, the equipment gathering hopper enables the selected multi-directional mineral flow to be densely led out. The transverse surface of the fiberglass chute has different slopes, which is very suitable for the separation of fine mineral particles. Beneficiation skills of spiral chute III. Featured FRP chute is particularly concerned among various gravity beneficiation equipment due to its low energy consumption, simple structure, small area occupied, simple operation, stable beneficiation, clear mineral separation, no moving parts, convenient Computerized maintenance management system, and large output per unit size. The equipment has a wide and relatively stable groove surface, and the area where the slurry flows in a laminar flow is quite large, making it more suitable for processing medium to fine (-4mm) ore particles. Fiberglass spiral chutes with diameters of 400, 600, 900, and 1200mm have been produced in China, Ф The processing capacity of 1200MM four head is about 4-6 t/h. Spiral Chute Beneficiation Techniques 4. Structural Composition: The spiral chute is composed of six parts: a feeding homogenizer, a feeding chute, a rotating chute, a product acquisition chute, an equipment gathering hopper, and a support bracket (including a cross or triangular frame). The spiral groove connected by the rotating disc is a key component. The spiral plate is made of fiberglass (fiber reinforced coal gangue), and a wear-resistant layer is pre made on the sorting surface of the rotating groove through bolts. She has the advantages of lightweight, strong, and durable consumer goods. Above the spiral groove, a multi tube feeding homogenizer is installed to evenly distribute the ore, and the operation is not complicated. The screening machine is not limited to being placed on the cross (or tripod) of the support table. The evenly distributed slurry is slowly fed onto the spiral groove surface through the feeding chute installed at the head of the rotating groove, and sorting is carried out. The tail end of the rotating groove is equipped with a valve block type new equipment to intercept the groove, allowing the sorted new products to be divided into three categories (or four categories) according to grade along the radial direction. Change the selection width of each new equipment by adjusting the position of the valve block. The new product gathering bucket is a concentric circular tube that gathers and exports various obtained mineral flows. The lateral plane of the spiral concentrator and the slope change of the curve are extremely suitable for the selection of fine-grained materials. Spiral chute beneficiation technique 5. Use This product is suitable for separating iron, ferrotitanium, chromite, pyrite, zircon, Rutile, monazite, phosphorus, tungsten, tin placer, tantalum niobium ore, niobium, and other non-ferrous metal ores, rare ore metals or non-metallic minerals with a specific gravity difference.
