The inner spiral chute manufacturer 1 describes that gravity separation is widely used in the beneficiation of metal and non-ferrous metals due to its low pollution and low cost. The fiberglass spiral chute is one of the gravity beneficiation machinery, with a structural feature of a cubic parabolic cross-section. It is used to handle finer particle sizes of -0.2mm, and does not require flushing water in the sorting process. The tail part of the chute is selected in sections to select fine, medium, and tailings. 2、 Use the method to erect the spiral chute, calibrate the vertical line, use an iron frame or wood to set a suitable position, use the mortar pump to send the sand ore to the two feeding ports above the spiral, enter the increased water, adjust the density of the mineral slurry, the mineral mortar naturally swirls from high to low, and a coherent centrifugal force occurs in the flow speed of the whirling inclined surface, and the gravity, Granularity and morphology of the sand ore are different, The efficiency is obtained by the gravity and centrifugal force of the swirling flow, which separates the ore and sand. The selected ore is discharged into the concentrate hopper and connected out through pipelines. The tailings are discharged into the tailings hopper and moved to the sand tank through pipelines. Then, they are discharged by a sand pump, completing the entire beneficiation process. Internal spiral chute manufacturer III. Features This machine is applicable to the separation of fine and small materials with a particle size of 0.3-0.02mm to obtain iron ore, ferrotitanium ore, chromite ore, pyrite, zircon, Rutile ore, monazite ore, phosphate ore, tungsten ore sand, tin, tantalum niobium ore, niobium and other non-ferrous metal ores, rare mineral metals or non-metallic mineral bodies with density and specific gravity differences. This product has the advantages of stable and simple selection process, wide range of ore concentration tolerance, high enrichment ratio, high recovery probability, small land area occupation, low water consumption, simple structure, no power, large processing capacity, simplified installation, simple operation, small investment, and quick results. Manufacturer 4 of the spiral chute within the range of . The structure of the fiberglass spiral chute is composed of six parts: a feeding distributor, a feeding chute, a spiral groove, a product selection groove, an equipment gathering hopper, and a groove bracket (including a cross or triangular frame). The rotating groove connected by spiral blades is a key accessory. The rotating plate is made of fiberglass (fiberglass reinforced coal gangue) and connected together by screws. The spiral groove has a pre made durable wear-resistant layer on the selected surface. He also has the advantage of lightweight, sturdy, and long-lasting consumables. The rotating groove is equipped with a multi tube feeding homogenizer to evenly distribute the ore, and the operation is not complicated. The screening machine is freely stacked on a cross (or tripod) on a support table. The evenly distributed mortar is slowly fed onto the surface of the spiral groove through the feeding chute installed at the beginning of the spiral groove, and sorting is carried out. The bottom of the rotating groove is installed in a valve block type new product cutting groove, and the selected new equipment is divided into three types (or four categories) of new products along the radial direction according to grade. Change the width of each new product by adjusting the position of the valve block. The new equipment gathering bucket is a concentric circular tube that allows the selected multi head ore flow to converge and export separately. The cross-section of the spiral chute and the slope of the curve change greatly in the separation of fine particle materials. Manufacturer 5 of the inner spiral chute. Application field: The application range of the spiral concentrator is to process 0.6-0.03mm and vein ores and minerals, but it is unfavorable for separation when the mud volume is high. 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. Manufacturer of internal spiral chute at
