Polyurethane Spiral Chute Manufacturing Tutorial 1. Equipment Description: A gravity beneficiation machine that utilizes the continuous centrifugal force generated by the slurry in the spiral rotation movement to achieve lightweight and heavy mineral separation. 2、 The spiral chute shall be set up by means of method, the vertical line shall be calibrated, the iron frame or wood shall be used to stabilize at the appropriate position, the sand ore shall be transported to the two ore feeding ports on the spiral roof by the slurry pump, the water shall be added, the concentration of mineral slurry shall be adjusted, the slurry shall naturally rotate from high to low, and a single coherent centrifugal force shall be generated in the rotating slope flow speed, and the difference in density, specific gravity, Granularity and morphology of the sand ore shall be obtained, Through the gravity and centrifugal force of the swirling flow, the sand and ore are separated. The selected ore is discharged into the concentrate hopper and connected out through pipelines. The tailings flow into the tailings hopper and are transported to the sand pit through pipelines. Then, they are discharged by a mortar pump, completing the entire beneficiation process. The special spiral concentrator is particularly concerned among many heavy concentration equipment because of its low power consumption, simple structure, small floor area, simple operation, stable beneficiation, clear mineral separation, no moving parts, convenient Computerized maintenance management system, large single area processing output, etc. The machinery has a wide and relatively flat groove surface, and the mineral mortar flows in a large area in a laminar flow, making it more suitable for handling medium to fine (-4mm) particle sized ores. We have produced fiberglass chutes with diameters of 400, 600, 900, and 1200MM in China, Ф The processing output of 1200mm four heads is about 4-6 tons per hour. A tutorial on the production of a 
polyurethane spiral chute. The structure of the spiral chute consists of six parts: a feeding homogenizer, a feeding chute, a rotating chute, a product cutting chute, an equipment gathering hopper, and a support bracket (including a cross or triangular frame). 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. Course V of polyurethane spiral chute production. Application field: FRP chute is suitable for separating fine iron ore, Ilmenite, Chromite, pyrite, tin ore, tantalum niobium ore, placer gold, coal mine, monazite ore, Rutile ore, zircon ore, rare earth ore, and other metal and nonferrous metal minerals with completely poor density ratio.
