Coal washing spiral chute 1. Explanation: The chute sorting includes a slope flow sorting process. Mineral mortar is fed to some inclined grooves or slopes, and under the push of water, the mineral particle group becomes loose and layered. The upper layer of light mineral quickly flows out of the groove, while the lower layer of heavy mineral material stays in the groove or is discharged from the bottom at low speed. After being collected, the selected ore and tailings are obtained. Spiral chutes are mining and beneficiation machines, especially ideal for sand mining on coasts, rivers, beaches, and streams. The equipment has the characteristics of suitable structure, simple installation, small land occupation, simple operation, stable beneficiation, clear ore separation, large processing volume, high efficiency, high concentration of beneficiation, high recovery rate, and reliable operation. There are also advantages such as small weight, moisture prevention, rust prevention, less corrosion resistance, and strong adaptability to fluctuations in ore feed volume, concentration, particle size, and grade. 2、 The application method is to erect the spiral concentrator, align it with the vertical line, use an iron frame or wood to stabilize it in a suitable position, and use a sand pump to deliver the ore sand to the two feeding ports above the spiral. The sand is mixed with supplementary water to adjust the density of the ore mortar. The ore mortar naturally swirls from high to low, and there is an inertial centrifugal force in the rotating slope flow rate, which varies in density, specific gravity, particle size, and state of the ore sand, The effect of gravity and centrifugal force is achieved through swirling flow, separating the sand from the ore. The selected ore flows into the concentrate hopper and is piped out, while the tailings enter the tailings hopper and are piped to the sand tank. They are then discharged by a sand pump, completing the entire beneficiation process. Coal washing spiral chute III. Features and highlights: 1. Super large-scale, large output, modern processing of ore materials requires the establishment of benefits based on scale effect. 2. Fine granulation is used for the treatment of fine particle grade mineral materials, especially for minerals with a particle size of -0.047mm. The original machine can basically guarantee the recovery of particles with a particle size of+0.047mm. 3. With the development of Hydraulics, two-phase flow, mechanical vibration, etc., the spiral chute has developed from the simple use of gravity and flow resistance to the combined use of centrifugal force, machine vibration force, magnetic force, etc. By using a composite force field to enhance the enrichment of useful mineral materials or the separation of fine and micro particles, the mineral recovery rate can be improved. 4. Based on energy conservation and environmental protection, it needs small floor area, space, water and electricity consumption. 5. Simple and flexible operation, stable sorting process, simple structure, and convenient maintenance management. coal washing spiral chute 4. The chute can be divided into three types according to the Granularity of the processed ore materials: (1) coarse particle spiral chute, the maximum particle size of the feed is more than 2-3MM, and the maximum can be 100-200mm. (2) Sand ore chute, processing 2-3 mm Granularity mineral aggregate. (3) Slime spiral chute, feeding Granularity<0.074MM. Spiral chute for coal washing V. The application scope of spiral concentrator is to separate fine grained iron ore, Ilmenite, Chromite, pyrite, cassiterite, tantalum niobium ore, placer gold, coal, monazite ore, Rutile ore, zircon sand, rare earth ore and other metal and nonferrous metal minerals with sufficient density and specific gravity difference. coal washing spiral chute
