Spiral chute polyurethane spraying 1. Introduction: Chute beneficiation belongs to the slope flow beneficiation process. Mortar is fed to some inclined grooves or slopes, and under the push of water flow, the mineral particle group becomes loose and layered. The upper layer of light minerals quickly flows out of the groove, while the lower layer of minerals with high specific gravity remain inside the groove or are discharged from the bottom at a low speed. After separation and collection, selected minerals and tailings can be obtained. The spiral concentrator is a machine for mining and beneficiation, making it ideal for mining ore in bays, river beds, sand banks, and streams. The equipment has the characteristics of correct structure, simple installation, small land occupation, simple operation, stable beneficiation, clear separation, large processing volume, high efficiency, high beneficiation enrichment ratio, high recycling rate, and reliable operation. It has the advantages of light weight, moisture resistance, rust prevention, corrosion resistance, and strong adaptability to fluctuations in feed volume, concentration, particle size, and grade. 2、 Apply skills to make the FRP chute stand up, calibrate the vertical line, fix the iron frame or wood at the appropriate position, and let the sand ore be sent to the two ore inlets on the spiral top by the mortar pump. Add make-up water to mobilize the density of the mineral slurry. The mineral slurry naturally swirls from top to bottom. There is a coherent centrifugal force in the rotating slope flow speed, which is different in density, specific gravity, Granularity and shape of the mineral sand, After the gravity and centrifugal force of the swirling flow, the ore and sand are separated, and the selected ore enters the concentrate hopper and is piped out. The tailings flow into the tailings hopper and are piped to the sand pit, and then discharged by a sand pump, completing the entire beneficiation process. spiral chute polyurethane spraying 3. Characteristics or advantages 1. Super large, strong processing capacity, modern processing mineral objective conditions through large-scale to create benefits. 2. Fine granulation: for the treatment of fine particle level minerals, the Granularity is -0.047MM, and the original equipment can generally ensure the recovery of+0.047mm. 3. With the development of Hydraulics, two-phase flow and machine vibration, spiral chutes have developed from simple use of gravity and flow resistance to composite use of centrifugal force, equipment vibration force, magnetic force, etc. By using a composite force field, the enrichment of useful minerals and the separation of fine and fine particles are increased, thereby improving the ore recovery rate. 4. With energy conservation and environmental protection as the fundamental starting point, the area and space should be small, and the water and electricity consumption should be small. 5. Simple and flexible operation, stable sorting process, simple structure, convenient for Computerized maintenance management system. Spiral chute polyurethane spraying 4. According to the particle size of the processed ore, the chute can be divided into three categories: (1) Coarse grained chute, with a maximum particle size of 2-3 millimeters or more for ore feeding, and a maximum of 100-200mm. (2) Sand chute, processing 2-3MM Granularity mineral aggregate. (3) Slime spiral chute, feeding Granularity<0.074mm. 5、 Application field: Spiral chutes are used for processing 0.6-0.03mm or vein ores and minerals, but high mud content is unfavorable for sorting. It has now been widely used for processing iron, tungsten, sand tin, tantalum niobium mines, beach or river sand mines, and sand gold, among others.
