Spiral chute production 1. Introduction: Gravity beneficiation is widely used in the beneficiation of metallic and non-metallic minerals due to its low environmental pollution and low cost. The fiberglass spiral chute is a type of gravity separation machine, characterized by a cubic parabolic shape on the cross-section. It is suitable for processing finer particles up to -0.2mm in size. In the sorting process, there is no need to add water for flushing, and the end of the chute is divided into sections to obtain fine, medium, and tailings. 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. Spiral chute production 3. Features 1. Stable selection process and simple control 2. Large range of allowable changes in ore concentration 3. High enrichment ratio and high recovery probability 4. Small footprint and water consumption 5. Simple structure without power 6. Large production 7. Simple installation and operation 8. Small investment and quick effect Spiral chute production 4. Structure of spiral chute composed of feeding homogenizer, feeding chute The rotating groove, product cutting groove, equipment gathering bucket, and this groove bracket (including a cross or tripod) are composed of six parts. The spiral groove connected by the rotating plate is a key accessory. The spiral plate is made of fiberglass (fiberglass reinforced with coal gangue) and connected together by bolts. The sorting surface of the rotating groove has a pre made wear-resistant layer. It has the advantages of lightweight, sturdy, and long-lasting consumer goods that are not easily damaged. The spiral groove is equipped with a multi tube feeding homogenizer for ore dressing, which is easy to operate. There is no need to restrict the stacking of mineral sievers on the cross (or tripod) of the support table. The evenly distributed mineral mortar is slowly fed to the surface of the spiral groove through the feeding groove at the beginning of the rotating groove, and then selected for operation. The bottom of the rotating groove is equipped with a valve block type new product selection groove, which allows the sorting equipment to be divided into three categories (or four types) of new products according to grade along the radial direction. Change the acquisition width of each new product by adjusting the position of the valve block. The new product gathering bucket is a concentric circular tube that collects and exports the intercepted variable mineral flows. The cross section and slope of the curve of the fiberglass chute are very suitable for the selection of fine particle materials. Manufacturing of spiral chute V. This machine is applicable to the separation of fine materials with Granularity of 0.3-0.02mm to obtain iron ore, ferrotitanium ore, chromite ore, pyrite ore, zircon sand, Rutile ore, monazite ore, phosphorus, tungsten sand, tin placer, tantalum niobium, niobium ore or other non-ferrous metal ores, rare metals and non-ferrous metal minerals with different density and specific gravity.
