Spiral chute of lump coal silo 1. Describe the impact of spiral chute on yield. The sorting of minerals by the chute belongs to the step of inclined flow sorting. Mineral mortar is provided on partially inclined inclined chutes or slopes. With the assistance of flowing water, the mineral particle group is not tight and layered. The upper part of the light mineral quickly flows out of the groove, while the lower layer of minerals with a larger proportion stay inside the groove or discharge from the bottom at a low speed. After being connected, concentrate and tailings can be obtained. Spiral chutes are machinery for mining and beneficiation, especially ideal for mineral mining in coastal areas, riverbanks, sandbanks, and streams. The product also has the characteristics of reasonable structure, simple installation, small footprint, simple operation, stable beneficiation, clear screening of ore, high yield, high efficiency, high beneficiation enrichment ratio, high recycling rate, and reliable operation. It has the advantages of small weight, moisture prevention, rust prevention, durability and corrosion resistance, and strong applicability to the fluctuation of feed volume and density, Granularity, and grade. 2、 Operating principle. The mineral mortar equivalent to the spiral chute of the lump coal silo is slowly fed onto the surface of the spiral groove through the feeding groove at the beginning of the rotating groove, and then selected for operation. The tail of the rotating groove is equipped with a valve type product acquisition groove, and the sorting equipment is divided into three categories according to grade along the radial direction. By adjusting the position of the valve block to change the cutting width of each product, the equipment gathering hopper enables the selected multi-directional mineral flow to be densely led out. The transverse plane of the fiberglass spiral chute has a change in the slope of the curve, which is extremely suitable for the selection of fine particle materials. 3. Advantages and characteristics of the spiral chute in the block coal silo: 1. Stable, easy to control, and with a large concentration range. 2. The production and processing of materials have a high yield, high enrichment ratio, and high recovery rate. 3. Small usage space, low water consumption, simple construction, and no need for power. 4. It is simple to install, easy to operate, with minimal investment and fast returns. The production video of the spiral chute in the lump coal silo includes six parts: a feeding homogenizer, a feeding groove, a rotating groove, a product intercepting groove, an equipment gathering hopper or a groove support (including a cross or triangular frame), etc. The spiral groove connected by the spiral plate is the main component. The rotating plate is made of fiberglass (fiber reinforced coal gangue), which is connected together through screws. The selected surface of the rotating groove has a predetermined wear-resistant layer. It also has the advantages of lightweight, sturdy, and durable consumer goods. Above the spiral groove, there is a multi tube feeding homogenizer for ore dressing and averaging, with simple control. The mineral screening device is freely placed on a cross (or tripod) on a support table. The evenly distributed mortar is slowly fed to the rotating groove surface by installing it on the feeding groove at the end of the spiral groove head, and sorting is carried out. The tail end of the spiral groove is installed in a valve block type new product acquisition groove, and the selected new products are divided into three categories (or four categories) of new equipment along the radial direction according to grade. Change the selection width of each new product by adjusting the orientation of the valve block. The new product gathering bucket is a concentric circular tube that allows the intercepted variable mineral flows to be gathered and exported separately. The cross section and slope of the curve of the spiral concentrator are particularly suitable for the separation of fine ore materials. 5、 Scope of adoption. The spiral chute is suitable for separating fine grained iron, ferrotitanium, ferrochrome, pyrite, tin ore, tantalum niobium, gold ore, coal, monazite ore, Rutile ore, zircon, rare earth ore or other metal and non-metallic mineral materials with sufficient specific gravity difference.
