Manufacturing of spiral chutes in coal bunkers

Introduction to the production of spiral chutes in coal bunkers: Gravity beneficiation is widely used in the beneficiation of metal and non-ferrous metals due to its low environmental pollution and low cost. The fiberglass spiral chute is a type of gravity separation machinery, characterized by a cubic parabolic shape on the cross-section, suitable for handling finer particle levels of -0.2MM. In the selection process, there is no need to add flushing water, and fine, medium, and tailings are segmented at the tail end of the chute. 2、 The working principle is the same: mineral mortar is slowly fed onto the rotating groove surface through the feeding chute installed at the end of the spiral groove head, and sorting is carried out. The bottom of the spiral groove is equipped with a valve block type product cutting groove, and the selected equipment is divided into three types according to grade along the radial direction. By adjusting the position 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 aggregated and exported. The cross section of the spiral concentrator and the change in slope of the curve are very suitable for the selection of fine-grained ore materials. 3. Characteristics or highlights of the production of spiral chutes in coal bunkers at . 1. Heavy duty and large processing capacity. Contemporary mineral material processing generally requires the use of scale effects to create benefits. 2. Fine granulation: for the treatment of fine and small particle size minerals, especially the treatment of ore materials with a particle size of -0.047MM, the original machinery can basically ensure the recovery of+0.047MM Granularity. 3. With the development of Hydraulics, two-phase flow, equipment vibration, etc., GRP spiral chute has developed from simple use of gravity and water blocking force to composite centrifugal force, mechanical vibration force, magnetic separation force, etc. Through a composite force field, the enrichment of useful minerals and the separation of fine and fine particles are enhanced, thereby increasing the ore recovery rate. 4. Based on energy conservation, consumption reduction and environmental protection, it should occupy a small area and space, and consume less water and electricity. 5. Simple and flexible operation, stable sorting process, simple structure, convenient for Computerized maintenance management system. The production of spiral chutes in coal bunkers is made up of six parts: a feeding homogenizer, a feeding chute, a spiral groove, an equipment cutting groove, a product gathering hopper, and a groove bracket (including a cross or triangular frame). The rotating groove connected by spiral blades is a key component. The rotating plate is made of fiberglass (fiberglass reinforced coal gangue) and connected together by bolts. The spiral groove has a pre made wear-resistant layer on the selected surface. She has the advantages of light weight, strength, durability, and the use of consumables. Above the rotating groove is a multi tube ore feeding homogenizer, which distributes ore evenly and has simple control. The mineral separator is not limited to being placed on a cross (or tripod) on a support table. The uniform slurry is slowly fed to the surface of the rotating groove through the feeding groove installed on the spiral groove head, and sorting is carried out. The tail of the spiral groove is installed in the valve type new product acquisition groove, and the selected new products are divided into three types (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 diverse mineral flows obtained to converge and export differently. The cross section of the spiral chute and the different slopes of the curve are particularly suitable for the separation of fine particle materials. 5、 Applicable fields The application scope of spiral concentrator is to separate fine grained iron ore, Ilmenite, Chromite, pyrite, tin ore, tantalum niobium ore, placer gold ore, coal mine, monazite ore, Rutile ore, zircon, rare earth ore and other metal and non nonferrous metal minerals with sufficient density and specific gravity difference.
