Spiral chute sorting

Spiral chute sorting: 1. Describing the steps of inclined surface flow sorting in chute beneficiation. The slurry is fed into a inclined chute or slope, and under the push of water, the mineral particle group is loose and layered. The lighter minerals in the upper layer quickly flow out of the groove, while the minerals in the lower layer with a higher specific gravity stay inside the groove or discharge from the bottom at a low speed. After being extracted, the concentrate and tailings are obtained. The spiral concentrator is an equipment for mining and beneficiation, especially ideal for sand mining in coastal areas, riverbanks, beaches, and streams. The equipment has the characteristics of appropriate structure, simple installation, small land occupation, simple operation, stable beneficiation, clear screening of ore, large output, high efficiency, high enrichment ratio, high recycling rate, and reliable operation. There are also advantages such as small weight, moisture resistance, rust prevention, corrosion resistance, and strong adaptability to fluctuations in ore feed volume or concentration, particle size, and grade. 2、 The working principle is the same: mineral mortar is slowly fed onto the rotating groove surface through the feeding groove installed at the end of the spiral groove head, and selection is carried out. The tail end of the spiral groove is equipped with a valve type product selection groove, which divides the sorting equipment 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 bucket allows the obtained variable mineral flow to be collected and exported. The cross section and slope of the curve of the spiral concentrator are very suitable for the separation of fine particle materials. 螺旋溜槽分选 Spiral Chute Sorting III. Features and Advantages 1. Ultra large-scale, large processing capacity, modern mineral processing principles require large-scale creation of benefits. 2. Fine granulation refers to the treatment of fine and small mineral particles, especially the treatment of mineral materials with a particle size of -0.047mm. Originally, the mechanical system could fundamentally ensure the recovery of+0.047mm particles. 3. With the development of Hydraulics, two-phase flow and equipment vibration, spiral chutes have developed from simple use of gravity and water resistance to composite application of centrifugal force, mechanical vibration force, magnetic force, etc. Through a composite force field, the enrichment of useful minerals and the separation of fine and fine particles are increased, resulting in an increase in ore recovery rate. 4. Based on energy saving, environmental protection and consumption reduction, it needs to occupy a small area, space, water and electricity consumption. 5. The simple operation is flexible, the sorting process is stable, and the structure is simple, which is convenient for Computerized maintenance management system. Spiral chute sorting 螺旋溜槽分选 IV. According to the Granularity of the processed ore materials, the chutes can be divided into three categories: (1) coarse size chutes. The maximum particle size of the feed is more than 2-3mm, and the maximum can be 100-200mm. (2) The ore chute handles 2-3mm sized ore. (3) Slime chute, feeding Granularity is less than 0.074MM. 5、 The application scope of spiral concentrator is to separate fine grained iron ore, Ilmenite, Chromite, pyrite, sand tin ore, tantalum niobium ore, sand gold, coal, monazite ore, Rutile ore, zircon sand, rare earth ore and other metal and nonferrous metal minerals with sufficient density and specific gravity difference.
