Spiral chute for coal preparation and beneficiation

Coal preparation and beneficiation spiral chute 1. Equipment introduction: A gravity beneficiation equipment that utilizes the continuous centrifugal force generated by mineral mortar in spiral motion to achieve lightweight and heavy mineral separation. 2、 The production principle is the same: the slurry is slowly fed to the rotating groove surface through the feeding chute at the head end of the spiral groove for sorting. The bottom of the spiral groove is equipped with a valve block type product acquisition groove, and the sorting equipment is divided into three types according to grade along the radial direction. Change the cutting width of each product by adjusting the orientation of the valve block, and gather the selected multi-directional mineral flow through the equipment gathering hopper. The slope change of the cross-section and curve of the fiberglass chute is very suitable for the selection of fine particle materials. Coal Dressing and Beneficiation Spiral Chute 3. Features 1. Stable and easy to operate sorting process 2. Wide range of allowable changes in feed density 3. High enrichment ratio and recycling rate 4. Small land occupation and less water consumption 5. Simple structure without power 6. Large processing output 7. Simple installation and operation 8. Low investment and quick efficiency of coal selection and beneficiation Spiral Chute 4 The structural composition of the spiral concentrator consists of six parts: a feeding homogenizer, a feeding trough, a spiral trough, an equipment selection trough, a product gathering hopper, and a trough bracket (including a cross or triangular frame). The spiral groove formed by connecting rotating discs is a key component. The spiral plate is made of fiberglass (fiberglass reinforced coal gangue) and connected together through screws. The sorting surface of the rotating groove has a pre designed durable wear-resistant layer. It has the advantages of lightweight, sturdy, durable, and durable consumer goods that are not easily damaged. A multi tube feeding homogenizer is installed above the rotating groove to sort minerals equally, making it easy to control. The concentrator does not need to be restricted from being placed on the cross (or tripod) of the support table. The evenly distributed slurry passes through the feeding chute installed at the head end of the spiral groove and slowly feeds onto the rotating groove surface for sorting. The tail of the spiral groove is equipped with a valve type new product acquisition groove, which allows the sorting equipment to be divided into three types (or four types) of new products along the radial direction according to grade. To adjust the orientation of the valve block and change the width of each new product, it is necessary to cut it off. The new equipment gathering bucket is a concentric annular tube that differentially collects and leads selected multi-directional mineral flows. The transverse surface of the fiberglass chute and the slope of the curve change greatly to adapt to the selection of fine-grained materials. 5、 Use This product is used to separate fine materials with a particle size of 0.3-0.02mm to obtain iron ore, ilmenite ore, chromite ore, pyrite ore, zircon sand, Rutile ore, monazite ore, phosphorus ethylene, 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.
