Special spiral chute for coal washing plant

Special spiral chute for coal washing plant I. It shows that the spiral chute is a combination of the characteristics of spiral concentrator, gravity separation spiral chute, shaking table and gold concentrator. After the relevant scientific research organized by the Ministry of Metallurgical Industry, the design, universities, concentrators and other units have passed the operation appraisal, and that the mechanical performance is excellent, the separation goal is improved, and it has won the scientific and technological research achievement award of the Ministry of Metallurgical Industry. It is now widely used in non-ferrous and Ferrous mines. This equipment is used to separate iron ore, ilmenite, chromite, pyrite, zircon, Rutile, monazite, phosphorus, tungsten, tin, tantalum niobium, niobium and other non-ferrous metal ores, rare metals and non-metallic minerals with gravity difference from fine materials with a particle size of 0.3-0.02 mm. 2、 The working principle of the spiral mineral separator is that the mineral separator is freely placed on the cross (or tripod) of the support table. The same slurry is slowly fed onto the spiral groove surface of the feeding groove installed on the rotating groove head for sorting. The tail end is equipped with a valve block type product cutting groove, allowing the sorting equipment to be divided into three (or four) types according to grade along the radial direction. Change the acquisition width of each product by adjusting the orientation of the valve block. The equipment gathering bucket is a concentric circular tube that distinguishes and aggregates the selected multi-directional mineral flow. The transverse surface of the fiberglass chute has a slope change that is extremely suitable for the selection of fine-grained materials. Special spiral chute for coal washery III. Characteristics and highlights 1. Heavy duty, large processing output, and scale effect is required to build revenue for contemporary mineral aggregate processing. 2. Fine granulation is used for the treatment of fine and small particle grade mineral materials, especially for minerals with a particle size of -0.047mm. The original machinery can basically ensure the recovery of+0.047mm particle size. 3. With the development of Hydraulics, two-phase flow, mechanical vibration, etc., the spiral chute has developed from the simple application of gravity and flow resistance to the composite application of centrifugal force, equipment vibration force, magnetic force, etc. By using a composite force field, the enrichment of useful mineral materials and the separation of fine and micro particles are increased, thereby improving the mineral recovery rate. 4. Based on energy conservation, environmental protection and consumption reduction, the land area and space occupied should be small, and water and electricity consumption should be small. 5. Simple and flexible operation, stable sorting process, simple structure, and convenient maintenance management. The special spiral chute for coal washing plant is composed of six parts: a feeding homogenizer, a feeding groove, a rotating groove, an equipment cutting groove, a product gathering hopper, and a groove support (including a cross or triangular frame). The spiral groove formed by the connection of spiral plates is a key component. The rotating plate is made of fiberglass (fiberglass reinforced coal gangue) and is bolted together. The selected surface of the rotating groove has a pre designed durable wear-resistant layer. It has the advantages of being lightweight, sturdy, durable, and not easily damaged consumer goods. The spiral groove is equipped with a multi tube feeding homogenizer to divide ore evenly, making it easy to operate. The concentrator is not limited to being placed on the cross (or tripod) of the support table. The evenly divided mineral mortar is slowly fed onto the spiral groove surface through the feeding chute at the head of the rotating groove for sorting. The tail of the rotating groove is installed in a valve type new product selection groove, and the selected new products are divided into three types (or four types) of new equipment along the radial direction according to grade. Change the 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 intercepted multi-directional mineral flow to converge and lead out. The cross section of the spiral chute and the different slopes of the curves are very suitable for sorting fine particle materials. 5、 The application scope of the spiral concentrator is to process 0.6-0.03mm and vein ores and minerals, but high mud content is unfavorable for beneficiation. At present, it has been widely used for processing iron ore, tungsten, tin ore, niobium tantalum ore, coastal or riverside placer and gold ore, and so on.
