Spiral chute sorting of sand ore

Introduction to a gravity beneficiation machine for separating light and heavy minerals by using a continuous centrifugal force during the rotary spiral movement of mortar. 2、 Use a method to make the fiberglass chute stand up, align it with the vertical line, use an iron frame or wood to stabilize it in a suitable direction, and use a sand pump to send the ore sand to the top two inlet ports of the spiral. The ore sand slurry enters to increase water and adjust its density. The mineral slurry naturally swirls from top to bottom, and an inertial centrifugal force occurs in the rotating inclined flow rate, resulting in differences in gravity, particle size, and shape of the sand ore, By separating the ore from the sand through the influence of the gravity and centrifugal force of the swirling flow, the concentrate enters the beneficiation hopper and is piped out. The tailings enter the tailings hopper and are piped to the sand tank, which is then discharged by a mortar pump, completing the entire beneficiation process. spiral chute for placer separation. 3. Characteristics 1. Stable separation process and simple control. 2. Large allowable range of ore feed concentration. 3. High enrichment ratio and high recovery probability. 4. Small area occupied, low water consumption. 5. Simple structure, no power required. 6. Large processing capacity. 7. Simple installation and easy operation. 8. Small investment, quick results. spiral chute for placer separation. 4 The structural composition of the spiral chute is composed of six parts: a feeding homogenizer, a feeding chute, a rotating chute, a product intercepting chute, an equipment gathering hopper, and a groove bracket (including a cross or triangular frame). The spiral groove connected by the rotating plate is a key accessory. The spiral plate is made of fiberglass (fiberglass reinforced coal gangue) and connected together through screws. The sorting surface of the rotating groove has one layer of pre designed durable wear-resistant layer. It has the advantages of lightweight, sturdy, and durable consumer goods. The spiral groove is equipped with a multi tube feeding homogenizer to screen minerals evenly, which is not cumbersome to operate. The mineral sorting equipment is freely stacked on the cross (or tripod) of the support table. The evenly distributed mortar is slowly fed to the spiral groove surface through the feeding groove installed at the head of the rotating groove, and the selection is carried out. The bottom of the rotating groove is installed in a valve block type new equipment to obtain the groove, allowing the sorted new products to be divided into three (or four) new products according to grade along the radial direction. Change the selection width of each new device by adjusting the position of the valve block. The new product gathering bucket is a concentric circular tube that distinguishes and converges the intercepted multi head ore flow. The cross-section of the fiberglass chute and the change in slope of the curve are particularly applicable for the selection of fine-grained materials. 5、 The use of spiral chutes in the field is suitable for processing 0.6-0.03MM and this vein ore as well as ore sand, but it is unfavorable for sorting when the mud content is high. It has now been widely used in the processing of iron, tungsten, tin ore, niobium tantalum ore, beach and riverbed placer or gold ore, and so on.
