Spiral chute for coal preparation

Spiral chutes for coal selection. 1、 Gravity beneficiation is widely used in metal and non-metallic ore processing due to its low environmental pollution and low cost. The spiral concentrator is one of the gravity separation equipment, with a structural characteristic that the cross-section presents a cubic parabolic state, suitable for processing finer particle sizes of -0.2MM. In the sorting process, there is no need to add flushing water, and fine, medium, and tailings are selected in sections at the tail of the tank. The actual collection of sulfur iron in spiral chutes. 2、 The technical principle is the same: the mortar is slowly fed to the rotating groove surface through a feeding groove installed on the spiral groove head for sorting. The tail end of the spiral groove is equipped with a valve block type product cutting groove, which divides the selected equipment into three types according to grade along the radial direction. By adjusting the orientation of the valve block to change the acquisition width of each product, the equipment gathering hopper allows the selected multi head ore flow to be differentiated and aggregated for export. The cross section of the spiral concentrator has different slopes, which is particularly suitable for the separation of small particle ore materials. 3 Spiral Chutes for Coal Preparation III. Highlights and Features. 1. High efficiency, high recovery rate, and correct mineral sorting; 2. Do not use power; 3. Small weight, anti rust, durable and anti wear, durable and anti corrosion; 4. Low cost, long application life; Strong applicability to fluctuations in ore feed volume, concentration, particle size, and grade; The friction force formed by the surface of 6 diamond sand makes the beneficiation effect better than other plastic surfaces. The spiral chute used for coal preparation is , and the spiral chute used for coal preparation is composed of six parts: a feeding homogenizer, a feeding chute, a spiral groove, a product acquisition groove, an equipment gathering hopper, and a groove support (including a cross or triangular frame). The rotating groove formed by connecting rotating discs is the main component. The spiral plate is made of fiberglass (fiberglass reinforced coal gangue) and is connected together through screws. The sorting surface of the spiral groove has a pre designed durable wear-resistant layer. She has the advantages of being lightweight, sturdy, and durable in using consumables. There is a multi tube feeding homogenizer above the rotating groove to screen minerals evenly, which is not cumbersome to operate. The screening machine does not need to be restricted from being placed on the cross (or tripod) on the support table. The uniform slurry is slowly fed to the surface of the spiral groove through the feeding groove on the rotating groove head, and sorting is carried out. The tail of the rotating groove is installed in a valve type new equipment selection groove, allowing the sorted new products to be divided into three (or four) types of new products according to grade along the radial direction. Change the width of each new device by adjusting the position of the valve block. The new product gathering bucket is a concentric circular tube that separates and merges the intercepted multi-directional mineral flows. The cross section of the spiral chute and the slope change of the curve are very applicable to the selection of fine materials. 5、 Application field. Glass fiber reinforced plastic chute is suitable for separating fine iron ore, Ilmenite, Chromite, pyrite, tin ore, tantalum niobium ore, placer gold, coal mine, monazite ore, Rutile ore, zircon ore, rare earth ore, and other metal and nonferrous metal minerals with completely enough density ratio difference.
