Key Technologies of Spiral Chutes

The key technology of spiral chutes is to introduce gravity separation, which is widely used in the beneficiation of metal 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 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. Key technology of spiral chute 3. Characteristics or advantages 1. Major type and strong processing capacity. Today's mineral aggregate processing is objectively conditional on large-scale to create revenue. 2. Fine granulation: for the treatment of fine and micro particle minerals, especially the treatment of ore materials with Granularity of -0.047MM, the original equipment can basically ensure the recovery of+0.047mm particle size. 3. With the development of Hydraulics, two-phase flow and machine vibration, the spiral concentrator has developed from a simple use of gravity and water resistance to a composite application of centrifugal force, equipment vibration force, magnetic separation force, etc. By using a composite force field, more useful minerals are enriched and the separation of fine particles from these fine particles increases the ore recovery rate. 4. Based on energy saving, environmental protection and consumption reduction, the 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 simple, and it is convenient for maintenance management. Key technology of spiral chute IV. According to the particle size of processed ore, the chute can be divided into three types: (1) coarse spiral chute. The maximum Granularity of ore feeding is more than 2-3 mm, and the maximum can reach 100-200 mm. (2) The sand ore chute is used to handle 2-3MM particle grade ore materials. (3) Slurry chute, feeding particle size less than 0.074 millimeters. 5、 Scope of application: The spiral concentrator is suitable for processing 0.6-0.03 millimeters of vein ore and this ore sand, but it is unfavorable for separation when the mud content is high. At present, it has been widely used for processing iron ore sand, tungsten, tin ore, tantalum niobium, coastal and riverside ore sand, and placer gold.
