Top view of spiral chute: 1. Describing the characteristics of gravity separation spiral chute, gravity separation spiral chute, shaking table, and gold separation centrifuge. After evaluation by relevant scientific research, design, universities, and concentrators organized by the Ministry of Metallurgical Industry, it is believed that this type of mechanical performance is excellent, the separation goal is advanced, and it has been awarded the Science and Technology Research Achievement Award by the Ministry of Metallurgical Industry. It has been widely used in non-ferrous and black mining metals. This equipment is suitable for separating iron ore, Ilmenite, Chromite, pyrite, zircon, Rutile, monazite, phosphorus, tungsten sand, tin, tantalum niobium, niobium with Granularity of 0.3-0.02 mm from other non-ferrous metal ores, rare mineral metals and non-metallic minerals with specific gravity difference. 2、 The technical principle is that the slurry is evenly distributed and slowly fed onto the surface of the spiral groove through the feeding groove installed at the head end of the rotating groove, implementing sorting. The tail of the rotating groove is equipped with a valve block type product acquisition groove, and the selected equipment is divided into three types according to grade along the radial direction. By adjusting the orientation of the valve block to change the cutting width of each product, the equipment gathering hopper allows the selected multi-directional mineral flow to be distinguished and gathered. The cross-section of the fiberglass chute and the slope change of the curve are particularly suitable for the separation of fine particle materials. Top view of spiral chute III. The characteristic spiral chute has attracted more attention in many gravity beneficiation equipment due to its 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 production. 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. Top view of the 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 cutting groove, an equipment gathering hopper or groove support (including a cross or triangular frame). The rotating groove connected by the rotating disc is a key component. The spiral plate is made of fiberglass (fiber reinforced coal gangue) and connected together by bolts. The sorting surface of the spiral groove has a pre made durable and wear-resistant layer. He also has the advantages of lightweight, strong, and durable consumables. The head of the rotating groove is equipped with a multi tube feeding homogenizer to sort minerals evenly, which is easy to control. The ore separator is not restricted from being placed on the cross (or tripod) of the support table. The evenly distributed mortar is slowly fed onto the surface of the rotating groove through a feeding groove installed at the end of the spiral groove head, and selected for operation. The tail end of the spiral groove is installed in a valve block type new product selection groove, allowing the sorting equipment to be divided into three types (or four types) of new products along the radial direction according to grade. Change the acquisition width of each new product by adjusting the position of the valve block. The new equipment gathering bucket is a concentric circular tube that converges and leads out the intercepted multiple ore flows. The lateral plane of the spiral concentrator and the change in slope of the curve are particularly suitable for the selection of small particle ore materials. Top view V of spiral chute: FRP chutes used in the field can be used to separate 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 non-metallic mineral materials with sufficient Density contrast.
