Acceptance standard for spiral chutes in coal mines

Acceptance standard for spiral chutes in coal mines: 1. Introduce that chute beneficiation belongs to the slope flow beneficiation step. Mortar is fed to some inclined grooves or inclined surfaces. With the assistance of flowing water, the mineral particle group is not tightened and layered. The upper part of the light mineral material is quickly discharged to the outside of the groove, while the lower layer of heavy mineral material is retained in the inner groove or slowly flows out from the bottom. After being picked up, fine beneficiation and tailings can be obtained. The spiral concentrator is a mining and beneficiation machine, especially ideal for mining and beneficiation of mineral sand in bays, rivers, beaches, and streams. The product has the characteristics of reasonable structure, simple installation, less land occupation, simple operation, stable beneficiation, clear mineral separation, strong processing ability, high efficiency, ultra-high beneficiation enrichment ratio, high recovery rate, and reliable operation. It has the advantages of light weight, moisture prevention, rust prevention, corrosion prevention, and strong adaptability to feed volume or density, Granularity, and grade fluctuations. 2、 Working principle. The spiral ore separator does not need to be limited to stacking on the cross (or tripod) of the support table. The same mortar is slowly fed onto the spiral groove surface through the feeding chute installed at the beginning of the rotating groove, and selected for operation. The bottom is equipped with a valve block type equipment cutting groove, which divides the sorted products into three (or four) categories according to grade along the radial direction. Change the selection width of each equipment by adjusting the orientation of the valve block. The product gathering bucket is a concentric circular tube that enables the diverse mineral flows obtained to converge and export differently. The transverse plane of the fiberglass spiral chute and the slope of the curve change, making it particularly suitable for the selection of small particle materials. Acceptance Standard for Spiral Chutes in Coal Mines III. Highlights: 1. Stable, easy to control, with a large concentration range., Acceptance standard for spiral chutes in coal mines 2. Strong production and processing capacity of mineral materials, high enrichment ratio, and high recovery probability. 3. The area is not occupied much, with low water consumption, simple structure, and no need for power. 4. Installation is simple and easy to operate, with low investment and fast returns. The acceptance standard for spiral chutes in coal mines is . 4、 The structural composition of the fiberglass chute consists of six parts: a feeding distributor, a feeding trough, a rotating trough, an equipment cutting trough, a product gathering hopper, and a trough support (including a cross or triangular frame). The spiral groove formed by the connection of spiral plates is a key component. The rotating plate is made of fiberglass (fiberglass reinforced coal gangue) and is bolted together. The selected surface of the rotating groove has a pre designed durable wear-resistant layer. It has the advantages of being lightweight, sturdy, durable, and not easily damaged consumer goods. The spiral groove is equipped with a multi tube feeding homogenizer to divide ore evenly, making it easy to operate. The concentrator is not limited to being placed on the cross (or tripod) of the support table. The evenly divided mineral mortar is slowly fed onto the spiral groove surface through the feeding chute at the head of the rotating groove for sorting. The tail of the rotating groove is installed in a valve type new product selection groove, and the selected new products are divided into three types (or four types) of new equipment along the radial direction according to grade. Change the width of each new product by adjusting the position of the valve block. The new product gathering bucket is a concentric circular tube that allows the intercepted multi-directional mineral flow to converge and lead out. The cross section of the spiral chute and the different slopes of the curves are very suitable for sorting fine particle materials. 5、 Utilizing the fiberglass spiral chute equipment in the field, the acceptance standard for coal mine spiral chutes is that fiberglass chutes are suitable for processing 0.6-0.03MM and vein ores as well as minerals, but high mud content is unfavorable for sorting. It is now widely used for processing iron ore, tungsten, sand tin, tantalum niobium ore, bay and riverbed ore sand or placer gold, and so on.
