Coarse coal slurry spiral chute 1. Overview of chute sorting, including inclined flow sorting process. The slurry is fed to a inclined groove or inclined surface with a certain inclination. With the assistance of flowing water, the ore particles are loose and layered. The upper layer of light mineral materials are quickly discharged to the outside of the groove, while the lower layer of minerals with a larger proportion are stagnant inside the groove or slowly discharged from the lower part. After the difference is connected, the selected ore and tailings can be obtained. Spiral chutes are mining and beneficiation machinery, making them ideal for sand mining and beneficiation in coastal areas, rivers, beaches, and streams. The product also has the characteristics of suitable structure, simple installation, small footprint, easy operation, stable beneficiation, clear beneficiation, strong processing capacity, high efficiency beneficiation concentration ratio, high recovery rate, and stable operation. It has the advantages of small weight, moisture prevention, rust prevention, durability and corrosion resistance, and strong adaptability to fluctuations in feed volume or density, Granularity, and grade. 2、 The slurry with the same technical principle is slowly fed onto the surface of the spiral groove through the feeding groove installed at the head of the rotating groove for selection. The tail end of the rotating groove is equipped with a valve block type equipment to select the groove, allowing the sorted products to be divided into three categories according to grade along the radial direction. By adjusting the position of the valve block to obtain the width of each device, the product gathering hopper will differentiate and densely extract the intercepted multi-directional mineral flow. The cross-section of the spiral chute and the slope change of the curve are particularly suitable for the separation of fine particle materials. Coarse slime spiral chute III. The characteristics of FRP chute, such as low power consumption, simple structure, small area occupied, simple operation, stable beneficiation, clear ore separation, no need for moving parts, convenient Computerized maintenance management system, and large processing output per unit size, have attracted much attention among many gravity beneficiation equipment. The machinery has a relatively wide and gentle groove surface, and the slurry flows in a laminar flow with a larger area, making it more suitable for processing medium to fine (-4mm) ore particles. We have made spiral chutes with diameters of 400, 600, 900, and 1200mm domestically, Ф The processing capacity of 1200MM four head is about 4-6 t/h. Coarse Coal Slime Spiral Chute 4. The structure of the fiberglass spiral chute is composed of a feeding device, a cross (tripod), a feeding chute, a spiral groove, a receiving groove, a gathering hopper, and a groove pillar. Coarse slime spiral chute V. Application field spiral chute is suitable for separating fine grained iron ore, ferrotitanium ore, chromite ore, pyrite ore, placer tin, tantalum niobium ore, gold ore, coal, monazite, Rutile, zircon, rare earth and other metal and nonferrous metal minerals with completely sufficient density and specific gravity difference.
