Chute type spiral screen

Chute spiral screen 1. Introduction Chute beneficiation belongs to the slope flow beneficiation process. Mortar is fed to some inclined grooves or slopes, and under the push of water flow, the mineral particle group becomes loose and layered. The upper layer of light minerals quickly flows out of the groove, while the lower layer of minerals with high specific gravity remain inside the groove or are discharged from the bottom at a low speed. After separation and collection, selected minerals and tailings can be obtained. The spiral concentrator is a machine for mining and beneficiation, making it ideal for mining ore in bays, river beds, sand banks, and streams. The equipment has the characteristics of correct structure, simple installation, small land occupation, simple operation, stable beneficiation, clear separation, large processing volume, high efficiency, high beneficiation enrichment ratio, high recycling rate, and reliable operation. It has the advantages of light weight, moisture resistance, rust prevention, corrosion resistance, and strong adaptability to fluctuations in feed volume, concentration, particle size, and grade. 2、 Technical principle: The spiral chute separator is not limited to being placed on the cross (or tripod) of the support table. Equal slurry is slowly fed to the spiral groove surface through the feeding chute at the end of the rotating groove head for sorting. The bottom is equipped with a valve block type equipment acquisition slot, allowing other products to be divided into three types (or four types) according to grade along the radial direction. Change the selection width of each device by adjusting the position of the valve block. The product gathering bucket is a concentric circular tube that collects and exports the intercepted variable mineral flows separately. The transverse surface of the fiberglass chute has a very variable slope, which is suitable for the selection of fine particle materials. Chute Type Spiral Screen 3. Featured spiral chutes have attracted more attention in many gravity beneficiation equipment due to their low power consumption, simple structure, small area occupation, simple operation, stable beneficiation, clear screening of ore, no moving parts, easy maintenance and management, and large single area output. The machine has a wide and stable groove surface, and the area where mineral mortar exhibits laminar flow is quite large, making it more suitable for processing medium to fine (-4MM) sized ores. We in China have produced spiral concentrators with diameters of 400, 600, 900, and 1200 millimeters, Ф The processing capacity of 1200mm four heads is about 4-6 tons/hour. Chute type spiral screen 4. The structure of the fiberglass spiral chute consists of six parts: a feeding homogenizer, a feeding chute, a rotating groove, an equipment acquisition groove, a product gathering hopper, and a groove bracket (including a cross or triangular frame). The spiral groove formed by connecting the rotating blades is a key component. The spiral plate is made of fiberglass (fiberglass reinforced coal gangue) and connected together by bolts. The sorting surface of the rotating groove has a pre made durable and wear-resistant layer. He also has the advantages of lightweight, sturdy, and long-lasting durability in consumer goods. The head of the spiral groove is equipped with a multi tube feeding homogenizer for ore dressing, which is also easy to operate. The ore separator is freely placed on the cross (or tripod) on the support table. The evenly distributed mortar is slowly fed onto the surface of the spiral groove through the feeding groove installed at the beginning of the rotating groove, and the selection is carried out. The bottom of the rotating groove is installed in a valve block type new product cutting groove, and the sorted new products are divided into three categories (or four types) of new equipment along the radial direction according to grade. Change the selection width of each new product by adjusting the position of the valve block. The new product gathering bucket is a concentric circular tube that allows the obtained multi head ore flow to be gathered and exported separately. The transverse plane of the spiral chute and the different slopes of the curves are very suitable for the selection of small particle mineral materials. 5、 The use of a field spiral concentrator is suitable for processing 0.6-0.03 millimeters or vein ore and this sand, but it is unfavorable for separation when the mud content is high. Currently, it has been widely used in the processing of iron, tungsten, sand tin, tantalum niobium, coastal or riverside sand mines, as well as sand gold mines.
