Acceptance of spiral chute installation in coal mines: 1. Clarify that chute sorting includes 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 method is to set up the fiberglass chute, 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 to the two feeding ports on the spiral top. Add water to adjust the concentration of the ore slurry, and the ore slurry will naturally rotate from top to bottom, generating a single inertial centrifugal force in the rotating slope flow rate, based on the differences in the specific gravity, particle size, and state of the sand ore, Through the action of gravity and centrifugal force generated by swirling flow, the sand and ore are separated. The concentrate flows into the beneficiation hopper and is piped out. The tailings are discharged into the tailings hopper and moved to the sand pit through a pipeline, and then discharged by a sand pump, completing the entire beneficiation process.

Features: Fiberglass spiral chutes are particularly concerned in many gravity beneficiation machines due to their low power consumption, simple construction, small footprint, easy operation, stable beneficiation, clear screening of minerals, no movement accessories, easy maintenance and management, large processing capacity per unit size, and other characteristics. The machine has a wide and stable groove surface, and the mortar has a large laminar flow area, which is more suitable for processing medium and fine (-4mm) Granularity ores. Our country has made spiral chutes with diameters of 400, 600, 900, and 1200MM, Ф The output of 1200mm four heads is about 4-6 t/h.

Structural Composition: The fiberglass chute is composed of six parts: a feeding homogenizer, a feeding chute, a rotating chute, an equipment acquisition chute, a product gathering hopper, or a groove bracket (including a cross or triangular frame). The spiral groove formed by connecting spiral pieces is the main component. The rotating plate is made of fiberglass (fiberglass reinforced coal gangue), which is connected together through screws. The selected surface of the rotating groove has a pre designed durable anti wear layer. It also has the advantages of lightweight, sturdy, and long-lasting consumer goods. The head of the spiral groove is equipped with a multi tube feeding homogenizer for screening ore, which is simple to operate. The mineral separator does not need to be restricted to placing on a cross (or tripod) on a support table. The evenly distributed slurry is slowly fed onto the spiral groove surface through a feeding chute installed at the head end of the rotating 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 (or four) types of new products according to grade along the radial direction. Change the width of each new product by adjusting the position of the valve block. The new equipment gathering bucket is a concentric annular tube that allows the selected variable ore flows to be densely exported. The transverse surface of the fiberglass spiral chute and the slope of the curve change, which is particularly suitable for the separation of small particle mineral materials. Acceptance of spiral chute installation in coal mine V. Application This product is used to separate fine materials with a particle size of 0.3-0.02mm to obtain iron ore, ferrotitanium ore, chromite ore, pyrite ore, zircon sand, Rutile ore, monazite ore, phosphoethylene, tungsten ore, placer tin, tantalum, niobium ore or other non-ferrous metal ores, rare metals and non-metallic ore bodies with different density and specific gravity.
