A new process for making spiral chutes: 1. Introduction: Gravity beneficiation spiral chutes combine the characteristics of gravity beneficiation spiral chutes, fiberglass spiral chutes, shakers, and beneficiation centrifuges. After scientific research organized by the Ministry of Metallurgical Industry, appraisal by departments such as design, universities, and this beneficiation company, it is recognized that this equipment has excellent performance and progress in beneficiation indicators. At the same time, it has won the Science and Technology Research Achievement Award from the Ministry of Metallurgy and has now been awarded in the field of non-ferrous metals Ferrous mines are very versatile. This product is suitable for sorting iron ore, ferrotitanium, ferrochrome, pyrite, zircon, Rutile, monazite, ethylene phosphate, tungsten, tin placer, tantalum, tantalum niobium and other nonferrous metal ores, rare ore metals and non-metallic ore bodies with density and specific gravity differences. 2、 Use the method to erect the spiral chute, calibrate the vertical line, fix it in the proper position with iron frame or wood, let the sand ore be sent to the two feeding ports on the top of the spiral by the slurry pump, add water, adjust the density of the mineral slurry, the mineral slurry naturally swirls from top to bottom, and generate a single coherent centrifugal force in the rotational slope flow speed, which can be distinguished by the specific gravity, Granularity and state of the mineral sand, Through the gravity and centrifugal force of swirling flow, the ore and sand are separated, and the selected ore is discharged into the concentrate hopper and connected out through pipelines. The tailings are discharged into the tailings hopper and transported to the sand pit through pipelines, and then discharged by a sand pump, completing the entire process of beneficiation. New Process for Manufacturing Spiral Chutes III. Highlights and Features 1. High efficiency, high recovery rate, and precise ore separation; 2. No power required; 3. Small weight, anti rust, wear-resistant, and strong corrosion resistance; Low cost and long service life; 5. Strong adaptability to fluctuations in ore feed volume, concentration, particle size, and grade; The frictional force on the surface of 6 diamond sand makes the beneficiation effect superior to other plastic surfaces. A New Process for Manufacturing a Spiral Chute 4. Structural Composition: The fiberglass chute is composed of six parts: a feeding distributor, a feeding trough, a rotating trough, a product cutting trough, an equipment gathering hopper or a trough bracket (including a cross or triangular frame), and so on. The spiral groove connected by the spiral plate is the main component. The rotating plate is made of fiberglass (fiber reinforced coal gangue), which is connected together through screws. The selected surface of the rotating groove has a predetermined wear-resistant layer. It also has the advantages of lightweight, sturdy, and durable consumer goods. Above the spiral groove, there is a multi tube feeding homogenizer for ore dressing and averaging, with simple control. The mineral screening device is freely placed on a cross (or tripod) on a support table. The evenly distributed mortar is slowly fed to the rotating groove surface by installing it on the feeding groove 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 acquisition groove, and the selected new products are divided into three categories (or four categories) of new equipment along the radial direction according to grade. Change the selection 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 intercepted variable mineral flows to be gathered and exported separately. The cross section and slope of the curve of the spiral concentrator are particularly suitable for the separation of fine ore materials. New process of spiral chute manufacturing V. This equipment is suitable for separating iron, ferrotitanium, ferrochrome, ferrosulfide, zircon, Rutile, monazite, phosphorus, ethylene, tungsten, sand tin, tantalum niobium, tantalum niobium of fine materials with a particle size of 0.3-0.02mm, and has a specific gravity difference to distinguish other nonferrous metal ores, rare metals and this non-metallic orebody.
