Spiral chute primary selection of tin ore 1. Equipment introduction: A gravity beneficiation equipment that utilizes the continuous centrifugal force generated by mineral mortar in spiral motion to achieve lightweight and heavy mineral separation. 2、 The mortar with uniform working principle is slowly fed onto the rotating groove surface through the feeding chute installed on the rotating groove head, and the selection is carried out. The bottom of the spiral groove is equipped with a valve type equipment selection 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 width of each device, the product gathering hopper aggregates and exports the intercepted variable mineral flow. The cross section of the spiral concentrator and the slope of the curve change greatly, making it suitable for the separation of fine ore particles. Spiral chute primary tin ore III. Features This machine is suitable for separating 0.3-0.02mm fine materials to obtain iron ore, Ilmenite, Chromite, pyrite, zircon sand, Rutile, monazite, phosphorus, tungsten, tin, tantalum, niobium ore and other non-ferrous metal ores, rare metals or non-metallic ore bodies with different density and specific gravity. This machine has the advantages of stable selection process, easy operation, wide range of feed density, ultra-high enrichment ratio, high recovery rate, small land area, low water consumption, simple structure, no need for power, large output, simplified installation, easy operation, low investment, and quick effectiveness. The preliminary selection of tin ore for the spiral chute is based on the structure. The fiberglass spiral chute is composed of six parts: a feeding homogenizer, a feeding chute, a spiral groove, a product acquisition groove, an equipment gathering hopper, and a groove support (including a cross or triangular frame). The rotating groove formed by connecting rotating discs is the main component. The spiral plate is made of fiberglass (fiberglass reinforced coal gangue) and is connected together through screws. The sorting surface of the spiral groove has a pre designed durable wear-resistant layer. She has the advantages of being lightweight, sturdy, and durable in using consumables. There is a multi tube feeding homogenizer above the rotating groove to screen minerals evenly, which is not cumbersome to operate. The screening machine does not need to be restricted from being placed on the cross (or tripod) on the support table. The uniform slurry is slowly fed to the surface of the spiral groove through the feeding groove on the rotating groove head, and sorting is carried out. The tail of the rotating groove is installed in a valve type new equipment selection groove, allowing the sorted new products to be divided into three (or four) types of new products according to grade along the radial direction. Change the width of each new device by adjusting the position of the valve block. The new product gathering bucket is a concentric circular tube that separates and merges the intercepted multi-directional mineral flows. The cross section of the spiral chute and the slope change of the curve are very applicable to the selection of fine materials. Spiral chute primary tin ore V. Scope of application Glass fiber reinforced plastic spiral chute is applicable to the separation of fine grained iron, ferrotitanium, ferrochrome, pyrite, tin ore, tantalum niobium ore, placer gold, coal, monazite, Rutile, zircon ore, rare earth ore and other metal and nonferrous metal minerals with sufficient density ratio difference.
