Spiral chute ore washing

Spiral chute ore washing 1. Overview: The chute sorting belongs to the slope flow sorting step. Mineral mortar is fed to a partially inclined chute or inclined surface. With the assistance of flowing water, the mineral particle group is not tightly fastened and layered. The lighter mineral material on the upper part is quickly discharged out of the groove, while the heavy mineral material on the lower part is stagnant inside the groove or flows out at a low speed from the lower end. After being connected, the selected ore or tailings are obtained. The spiral concentrator is a mechanical device for mining and beneficiation, making it ideal for sand mining in coastal, river, sand beach, and stream beds. The product has the characteristics of appropriate structure, easy installation, small land occupation, easy operation, stable beneficiation, clear mineral separation, high yield, high-efficiency beneficiation, ultra-high enrichment ratio, high recycling rate, and reliable operation. It has the advantages of light weight, moisture prevention, rust prevention, corrosion resistance, and strong applicability to fluctuations in feed volume and density, Granularity, and grade. 2、 The method of use is to set up the fiberglass chute, calibrate the vertical line, use an iron frame or wood to fix it in the appropriate position, and use a slurry pump to send the sand ore to the two feeding ports on the spiral head to supplement water and adjust the density of the mineral sand slurry. The mineral sand slurry naturally rotates from top to bottom, and an inertial centrifugal force occurs in the flow speed of the rotating inclined plane, which varies in density, specific gravity, particle size, and morphology of the sand ore, Under the action of swirling gravity or centrifugal force, the sand and ore are separated. The selected ore flows into the concentrate hopper and is piped out, while the tailings flow into the tailings hopper and are piped to the sand pit. Then, they are discharged by a sand pump, completing the entire beneficiation process. 螺旋溜槽洗矿 Spiral chute ore washing 3. Features 1. Stable and easy control of the sorting process 2.

Structural composition of the spiral concentrator consists of a feed homogenizer, a feed chute The rotating groove, product cutting groove, equipment gathering bucket, and groove bracket (including cross or triangular frame) are composed of six parts. The spiral groove formed by connecting the spiral pieces is the main component. The rotating plate is made of fiberglass reinforced coal gangue and connected together through screws. The sorting surface of the rotating groove has a pre made durable wear-resistant layer. It also has the advantages of lightweight, sturdy, durable, and durable consumer goods. The head of the spiral groove is equipped with a multi tube ore feeder to evenly separate minerals, and the control is not complicated. The concentrator is not limited to being placed on a cross (or tripod) on a support table. The evenly distributed mortar is slowly fed onto the surface of the spiral groove through the feeding chute installed at the beginning of the rotating groove, and sorting is carried out. The tail end of the rotating groove is equipped with a valve type new product acquisition groove. The selected new products are divided into three (or four) types 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 obtained multi-directional mineral flow to be collected and exported separately. The cross section and slope of the spiral chute are extremely suitable for the selection of fine particle materials. 5、 The application scope of fiberglass chute is used for processing 0.6-0.03 millimeters and this vein or placer ore, but it is unfavorable for sorting when the mud content is high. Currently, it has been widely used for processing iron ore, tungsten, tin ore, tantalum niobium ore, coastal and riverine minerals, and gold ore.
