New type of grooved spiral chute

A new type of grooved spiral chute 1. Introduction: The chute beneficiation belongs to the slope flow beneficiation 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、 Technical principle: The fiberglass spiral chute mineral separator is not limited to stacking on the cross (or tripod) of the support table. The average mineral mortar is slowly fed onto the spiral groove surface through a feeding groove installed at the end of the rotating groove head for sorting. The tail is equipped with a valve type product selection slot, which divides the selection equipment into three types (or four types) according to grade along the radial direction. Change the cutting width of each product by adjusting the orientation of the valve block. The equipment gathering bucket is a concentric circular tube that allows the obtained multi head ore flow to gather and lead out. The cross section of the spiral chute is particularly suitable for the selection of fine ore particles due to changes in the slope of the curve. New grooved spiral chute 3. Features 1. Stable and easy to operate sorting process 2. Wide range of allowable changes in feed density 3. Ultra high enrichment ratio and high recycling rate 4. Small occupied area and low water consumption 5. Simple structure without power 6. Strong processing ability 7. Simple installation and operation 8. Low investment and quick results New grooved spiral chute 4. Classification according to the processed ore particle size, The chutes can be divided into three types: (1) coarse chute, the maximum Granularity of ore feeding is more than 2-3MM, and the maximum can reach 100-200MM. (2) Sand ore chute, processing 2-3 mm particle grade ore material. (3) Slurry spiral chute, feeding particle size ＜ 0.074mm. 5、 The application range of fiberglass chute is 0.6-0.03mm for processing vein ore and ore sand, but it is unfavorable for sorting when the mud content is high. Nowadays, it has been widely used in the treatment of iron, tungsten, sand tin, tantalum niobium, coastal and riverbed mineral sand and sand gold. New grooved spiral chute New grooved spiral chute
