The sorting process of spiral chutes

The sorting process of spiral chutes: 1. Introduction: Chute beneficiation belongs to the slope flow sorting step. The mortar is fed to some inclined grooves or slopes, and with the assistance of flowing water, the mineral particle group is not tightened and layered. The upper part of the light mineral material is quickly discharged to the outside of the groove, while the lower layer of heavy mineral material is retained in the inner groove or slowly flows out from the lower end. After being picked up, fine beneficiation and tailings can be obtained. The spiral concentrator is a mining and beneficiation machine, especially ideal for mining and beneficiation of mineral sand in bays, rivers, beaches, and streams. The product has the characteristics of reasonable structure, simple installation, less land occupation, simple operation, stable beneficiation, clear mineral separation, strong processing ability, high efficiency, ultra-high beneficiation enrichment ratio, high recovery rate, and reliable operation. It has the advantages of light weight, moisture prevention, rust prevention, corrosion prevention, and strong adaptability to feed volume or density, Granularity, and grade fluctuations. 2、 Use skills to make the spiral concentrator stand up, align it with the vertical line, use an iron shelf or wood to stabilize it in a suitable position, use the sand pump to transport the ore sand to the two feeding ports on the spiral head, add make-up water, and adjust the concentration of the ore slurry. The mineral slurry naturally swirls from high to low, and an inertial centrifugal force occurs in the flow rate of the swirling inclined surface to obtain the difference in gravity, Granularity and shape of the sand ore, By achieving the efficiency of gravity or centrifugal force through swirling flow, the ore and sand are separated, and the concentrate is discharged into the beneficiation hopper and connected out through pipelines. The tailings flow into the tailings hopper and are connected to the sand pit through pipelines, and then discharged by a mortar pump, completing the entire beneficiation process. The sorting process of the spiral chute is characterized by its three characteristics and advantages: 1. It is ultra large and has strong processing capacity. Modern mineral material processing requires scale to create profits. 2. Fine granulation: fine particle grade mineral materials, especially minerals with Granularity of -0.047mm, can be treated. The original equipment can basically guarantee the recovery of+0.047mm particle size. 3. With the development of Hydraulics, two-phase flow, machine vibration, etc., GRP spiral chutes have developed from simple application of gravity and flow resistance to 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 particles and micro particles are enhanced, thereby improving the mineral recovery rate. 4. The basic starting point is to save energy, reduce energy consumption and protect the environment. 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 it is convenient for maintenance and management. The sorting process of the spiral chute is divided into six parts: a feeding homogenizer, a feeding groove, a spiral groove, an equipment selection groove, a product gathering hopper, and a groove bracket (including a cross or triangular frame). The rotating groove formed by connecting rotating pieces is a key component. The spiral plate is made of fiberglass (fiberglass reinforced coal gangue) and connected together through screws. The sorting surface of the spiral groove has a pre designed durable and wear-resistant layer. He also has the advantages of lightweight, sturdy, and durable consumables. A multi tube ore feeding homogenizer is installed above the rotating groove to screen minerals, which is also easy to operate. The screening machine is freely placed on the cross (or tripod) of the support table. The uniform mineral mortar is slowly fed onto the rotating groove surface through the feeding groove on the spiral groove head for selection. The bottom of the spiral groove is installed in a valve block type new equipment cutting groove, and the sorted new products are divided into three (or four) types of new products along the radial direction according to grade. Change the selected width of each new equipment 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 change in the slope of the cross-section and curve of the fiberglass chute is particularly applicable for the selection of fine-grained mineral materials. 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.
