Installation video of spiral chute coal washing: 1. Equipment introduction: A gravity separation machine used for mineral mortar to achieve lightweight and heavy mineral sorting due to the inertial centrifugal force that occurs during rotary spiral motion. 2、 Working principle: The fiberglass spiral chute concentrator does not need to be restricted from being placed on the cross (or tripod) of the support table. The same mineral mortar is slowly fed onto the surface of the rotating groove through the feeding chute installed at the head of the spiral groove for sorting. A valve type equipment is installed at the tail to obtain a slot, allowing the selected products to be divided into three categories (or four categories) according to grade along the radial direction. Change the selection width of each device by adjusting the orientation of the valve block. The product gathering bucket is a concentric circular tube that differentially merges and leads out the intercepted multi-directional mineral flow. The transverse plane and slope of the curve of the spiral concentrator are particularly suitable for the separation of fine-grained materials. Spiral chute coal washing installation video III. Highlights and features: 1. High efficiency, high recycling rate, and correct screening of minerals; 2. No power required; 3. Lightweight, rust resistant, wear-resistant, and not easily corroded; 4. Low cost, long service life; 5. It is applicable to the fluctuation of feed volume, density, Granularity and grade; The friction caused by the appearance of 6 diamond sand makes the beneficiation efficiency better than other plastic surfaces. The installation video of the coal washing system for the spiral chute 4. The structural composition of the fiberglass chute consists of six parts: a feeding homogenizer, a feeding chute, a rotating chute, an equipment intercepting chute, a product gathering hopper, and a groove bracket (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. Video of spiral chute coal washing installation V. Scope of use: FRP spiral chute is suitable for separating fine grained iron, ferrotitanium, ferrochrome, pyrite ore, placer tin ore, tantalum niobium, gold, coal, monazite, Rutile, zircon, rare earth or other metal and non-metallic mineral materials with sufficient Density contrast.
