Gravity dust removal spiral chute 1. Introduction: Gravity beneficiation is widely used in the beneficiation of metallic and non-metallic ores due to its low pollution and low cost. Fiberglass reinforced plastic chute is one of the gravity separation equipment, with a structural feature that the cross-section presents a cubic parabolic state, suitable for processing finer particle sizes of -0.2MM. During the selection process, do not add water for flushing, and divide the chute into sections at the end to select fine, medium, and tailings. 2、 The method of use is to set up the spiral concentrator, calibrate the vertical line, fix the iron shelf or wood in the proper position, send the sand ore to the two ore feeding ports on the spiral top by the slurry pump, add water, adjust the density of the mineral slurry, the slurry naturally swirls from high to low, generate a single coherent centrifugal force in the flow speed of the rotating slope, and obtain the difference in the specific gravity, Granularity and state of the sand ore, Through the action of gravity and centrifugal force obtained through swirling flow, the sand and ore are separated, and the concentrate is discharged into the beneficiation hopper and connected out through pipelines. The tailings flow into the tailings hopper and are moved to the sand tank through pipelines, and then discharged by a sand pump, completing the entire beneficiation process. Gravity dust removal spiral chute III. The characteristic 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 screening minerals, no moving accessories, convenient Computerized maintenance management system, large production capacity per area, etc. The machine has a wide and relatively flat groove surface, and the area where the slurry flows in a laminar flow is relatively large, making it more suitable for processing medium to fine (-4mm) sized ores. We have made 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/hour. Gravity dust removal ash spiral chute 4. The structure of 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 bracket (including a cross or triangular frame). The rotating groove formed by connecting rotating pieces is the main component. The spiral plate is made of fiberglass (fiberglass reinforced coal gangue) and connected together through screws. The sorting surface of the spiral groove has a pre made durable and wear-resistant layer. It also has the advantages of lightweight, solid, and durable consumables. The head of the rotating groove is equipped with a multi tube feeding homogenizer for ore dressing, which is simple and convenient to control. The sorting machine does not need to be placed on the cross (or tripod) of the support table to restrict stacking. The uniform mineral mortar is slowly fed onto the surface of the rotating groove through the feeding groove installed at the end of the spiral groove head for selection. The tail of the spiral groove is installed in a valve type new product selection groove, allowing the sorted new products to be divided into three types (or four types) of new equipment along the radial direction according to grade. Change the cutting width of each new product by adjusting the orientation of the valve block. The new product agglomeration bucket is a concentric circular tube that leads to the differential aggregation of selected multi-directional mineral flows. The cross section of the fiberglass chute has different slopes, which is very suitable for the selection of fine particle mineral materials. Gravity dust removal ash spiral chute V. This machine is suitable for separating iron ore, ilmenite, Chromite, pyrite, zircon sand, Rutile ore, monazite ore, phosphate ore, tungsten ore sand, tin ore, tantalum niobium ore, niobium ore and other nonferrous metal ore, rare metal and non-metallic ore bodies with specific gravity differences.
