The production method of spiral chutes for express delivery

The production method of spiral chutes for express delivery: 1. Introduction: Chute sorting belongs to the inclined surface flow sorting process. Mineral mortar is fed to some inclined grooves or slopes, and under the push of water, the mineral particle group is loose and layered. The upper part of the light mineral quickly flows out of the groove, while the lower layer of minerals with a larger proportion stay inside the groove or discharge from the bottom at a low speed. After obtaining the difference, the selected ore and tailings can be obtained. Spiral chutes are machines for mining and beneficiation, making them ideal for sand mining in coastal areas, riverbanks, sandbanks, and river beds. The product has the characteristics of correct structure, simple installation, small land occupation, easy operation, stable beneficiation, clear screening of ore, large production capacity, high efficiency, high beneficiation 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 or density, Granularity, and grade. 2、 Technical principle: The fiberglass spiral chute mineral separator is not limited to stacking on the cross (or tripod) of the support table. The average mineral mortar is slowly fed onto the spiral groove surface through a feeding groove installed at the end of the rotating groove head for sorting. The tail is equipped with a valve type product selection slot, which divides the selection equipment into three types (or four types) according to grade along the radial direction. Change the cutting width of each product by adjusting the orientation of the valve block. The equipment gathering bucket is a concentric circular tube that allows the obtained multi head ore flow to gather and lead out. The cross section of the spiral chute is particularly suitable for the selection of fine ore particles due to changes in the slope of the curve. The manufacturing method of the spiral chute used in the express delivery is 3. Highlights and characteristics: 1. Stable, easy to control, and with a relatively large concentration range. 2. The material production and processing capacity is large, with a high enrichment ratio and a high probability of recovery. 3. The area is not occupied much, consumes less water, has a simple structure, and does not require power. 4. Easy installation, simple operation, low investment, and quick returns. The production method of spiral chutes for express delivery is 4. The structural composition of a fiberglass spiral chute is composed of six parts: a feeding homogenizer, a feeding chute, a spiral groove, a product selection groove, an equipment gathering hopper, and a groove bracket (including a cross or triangular frame). The rotating groove connected by spiral blades is a key accessory. The rotating plate is made of fiberglass (fiberglass reinforced coal gangue) and connected together by screws. The spiral groove has a pre made durable wear-resistant layer on the selected surface. He also has the advantage of lightweight, sturdy, and long-lasting consumables. The rotating groove is equipped with a multi tube feeding homogenizer to evenly distribute the ore, and the operation is not complicated. The screening machine is freely stacked 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 spiral groove, and sorting is carried out. The bottom of the rotating groove is installed in a valve block type new product cutting groove, and the selected new equipment is divided into three types (or four categories) of new products along the radial direction according to grade. Change the width of each new product by adjusting the position of the valve block. The new equipment gathering bucket is a concentric circular tube that allows the selected multi head ore flow to converge and export separately. The cross-section of the spiral chute and the slope of the curve change greatly in the separation of fine particle materials. 5、 The fiberglass spiral chute is suitable for processing 0.6-0.03MM and vein or placer ores, but it is unfavorable for sorting when the mud content is high. Now it has been widely used for processing iron ore, tungsten, tin ore, niobium tantalum ore, coastal and riverside ore sands, and gold mines.
