Spiral chute selection of lead-zinc tailings

Spiral chute beneficiation of lead-zinc tailings 1. Introduction: The chute beneficiation belongs to the slope flow beneficiation process. Mortar is fed to some inclined grooves or slopes, and under the push of water flow, the mineral particle group becomes loose and layered. The upper layer of light minerals quickly flows out of the groove, while the lower layer of minerals with high specific gravity remain inside the groove or are discharged from the bottom at a low speed. After separation and collection, selected minerals and tailings can be obtained. The spiral concentrator is a machine for mining and beneficiation, making it ideal for mining ore in bays, river beds, sand banks, and streams. The equipment has the characteristics of correct structure, simple installation, small land occupation, simple operation, stable beneficiation, clear separation, large processing volume, high efficiency, high beneficiation enrichment ratio, high recycling rate, and reliable operation. It has the advantages of light weight, moisture resistance, rust prevention, corrosion resistance, and strong adaptability to fluctuations in feed volume, concentration, particle size, and grade. 2、 Use skills to make the spiral concentrator stand up, align it with the vertical line, use an iron shelf or wood to stabilize it in a suitable position, use the sand pump to transport the ore sand to the two feeding ports on the spiral head, add make-up water, and adjust the concentration of the ore slurry. The mineral slurry naturally swirls from high to low, and an inertial centrifugal force occurs in the flow rate of the swirling inclined surface to obtain the difference in gravity, Granularity and shape of the sand ore, By achieving the efficiency of gravity or centrifugal force through swirling flow, the ore and sand are separated, and the concentrate is discharged into the beneficiation hopper and connected out through pipelines. The tailings flow into the tailings hopper and are connected to the sand pit through pipelines, and then discharged by a mortar pump, completing the entire beneficiation process. spiral chute for selecting lead-zinc tailings. 3. Characteristics and advantages. 1. Ultra large-scale, large processing capacity, modern mineral processing principles require large-scale creation of benefits. 2. Fine granulation refers to the treatment of fine and small mineral particles, especially the treatment of mineral materials with a particle size of -0.047mm. Originally, the mechanical system could fundamentally ensure the recovery of+0.047mm particles. 3. With the development of Hydraulics, two-phase flow and equipment vibration, spiral chutes have developed from simple use of gravity and water resistance to composite application of centrifugal force, mechanical vibration force, magnetic force, etc. Through a composite force field, the enrichment of useful minerals and the separation of fine and fine particles are increased, resulting in an increase in ore recovery rate. 4. Based on energy saving, environmental protection and consumption reduction, it needs to occupy a small area, space, water and electricity consumption. 5. The simple operation is flexible, the sorting process is stable, and the structure is simple, which is convenient for Computerized maintenance management system. The spiral chute for selecting lead-zinc tailings is composed of six parts: a feeding homogenizer, a feeding chute, a spiral groove, a product acquisition groove, an equipment gathering hopper or a groove bracket (including a cross or triangular frame), etc. The main component is the rotating groove connected by the rotating disc. The spiral plate is made of fiberglass reinforced coal gangue, and is bolted together. The selection surface of the spiral groove has a pre made durable and wear-resistant layer. He also has the advantages of light weight, firmness, and durability in consumables. The head of the rotating groove is equipped with a multi tube feeding homogenizer to sort minerals evenly, and the control is simple. The concentrator is freely placed on the cross (or tripod) of the support table. The uniform slurry passes through the feeding trough installed on the spiral groove head and slowly feeds onto the rotating groove surface for sorting. The tail end of the spiral groove is installed in a valve block type new product cutting groove, and the sorting equipment is divided into three types (or four types) of new products 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 equipment gathering bucket is a concentric circular tube that gathers and leads out the obtained multi-directional mineral flow. The cross section of the spiral concentrator and the slope change of the curve are extremely suitable for the separation of fine particle ore materials. 5、 The application range of fiberglass chute is 0.6-0.03mm for processing vein ore and ore sand, but it is unfavorable for sorting when the mud content is high. Nowadays, it has been widely used in the treatment of iron, tungsten, sand tin, tantalum niobium, coastal and riverbed mineral sand and sand gold.
