The original design of spiral chutes

The original introduction of spiral chutes is that gravity separation is widely used in the beneficiation of metallic and non-metallic ores due to its low environmental pollution and low cost. Glass fiber reinforced plastic chute is one of the gravity beneficiation equipment, with a structural feature of a cubic parabolic cross-section. It is suitable for processing finer particle sizes of -0.2mm. In the sorting step, there is no need to add water to wash, and the bottom of the chute is divided into sections to obtain refined, medium, and tailings. 2、 The production principle is the same: the slurry is slowly fed to the rotating groove surface through the feeding chute at the head end of the spiral groove for sorting. The bottom of the spiral groove is equipped with a valve block type product acquisition groove, and the sorting equipment is divided into three types according to grade along the radial direction. Change the cutting width of each product by adjusting the orientation of the valve block, and gather the selected multi-directional mineral flow through the equipment gathering hopper. The slope change of the cross-section and curve of the fiberglass chute is very suitable for the selection of fine particle materials. The original three characteristics and advantages of the spiral chute are: 1. Heavy duty and large production capacity. Today, in principle, processing minerals requires scale efficiency to create profits. 2. Fine granulation: fine and small particle grade mineral materials, especially minerals with Granularity of -0.047MM, can be treated. The original equipment can basically ensure the recovery of+0.047mm particle size. 3. With the development of Hydraulics, two-phase flow and equipment vibration, spiral chutes have developed from simple use of gravity and flow resistance to the level of composite centrifugal force, mechanical vibration force, magnetic force, etc. By using a composite force field, the enrichment of useful mineral materials and the separation of fine or fine particles can be enhanced, thereby improving the mineral recovery rate. 4. The basic starting point is to save energy, reduce consumption and environmental protection. The land area and space occupied should be small, and the water and electricity consumption should be small. 5. The operation is simple and flexible, the sorting process is stable, the structure is simple, and it is convenient for maintenance management. The original structure of the spiral chute is composed of six parts: a feeding homogenizer, a feeding groove, a rotating groove, a product cutting groove, an equipment gathering hopper, and a groove bracket (including a cross or triangular frame). The spiral groove formed by connecting the spiral pieces is the main component. The rotating plate is made of fiberglass (fiber reinforced coal gangue) and is bolted together. The rotating groove has a durable wear-resistant layer made in advance on each side. It has the advantages of light weight, firmness, and durability, which are not easy to damage consumer goods. The head of the spiral groove is equipped with a multi tube feeding homogenizer for ore dressing and averaging, which is easy to control. The sorting machine does not need to be placed on the cross (or tripod) of the support table. The evenly divided mineral mortar is slowly fed to the spiral groove surface through the feeding groove on the rotating groove head for sorting. The tail end of the rotating groove is equipped with a valve block type new equipment selection groove, which will classify the selected new products into three (or four) new products according to grade along the radial direction. To adjust the orientation of the valve block and change the width of each new equipment, it is necessary to cut it off. The new product gathering bucket is a concentric circular tube that allows the obtained multi-directional mineral flow to be densely drawn out. The horizontal plane of the spiral concentrator and the slope change of the curve are extremely suitable for the separation of small particle ore materials. 5、 The application range of fiberglass spiral chute is suitable for processing 0.6-0.03MM and this vein ore and mineral, but it is unfavorable for separation when the mud content is high. Nowadays, it is widely used for processing iron ore, tungsten, tin ore sand, niobium tantalum ore, coastal and riverside placer mines, and sand gold mines. Original of spiral chute
