Coal bunker spiral chute production process 1. Equipment description: A gravity beneficiation machine that utilizes the continuous centrifugal force generated by the slurry in the spiral rotation movement to achieve lightweight and heavy mineral separation. 2、 The mineral mortar with the same working principle is slowly fed onto the rotating groove surface through the feeding chute installed at the head of the spiral groove for sorting. The bottom of the spiral groove is equipped with a valve block type product acquisition 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 cutting width of each product, the equipment gathering hopper allows the selected multi head ore flow to be collected and exported separately. The cross section of the spiral concentrator, with a change in the slope of the curve, is extremely suitable for the selection of fine-grained materials. Manufacturing process of coal bunker spiral chute III. The characteristic spiral chute has attracted more attention among various gravity separation machines due to its low power consumption, simple structure, small land occupation, simple operation, stable beneficiation, clear ore separation, no moving parts, convenient Computerized maintenance management system, large single area processing capacity, etc. The machine has a wide or gentle groove surface, and the area where the mortar flows in laminar flow is large, which is more suitable for processing medium and fine (-4MM) Granularity ores. Spiral concentrators with diameters of 400, 600, 900, and 1200mm have been produced domestically, Ф The production capacity of 1200mm four heads is about 4-6 T/H. The manufacturing process of the spiral chute in the coal bunker is four. The fiberglass chute is composed of a feeding equalizer, a cross (tripod), a feeding chute, a rotating groove, a receiving groove, a gathering hopper, and a groove pillar. The production process of the spiral chute in the coal bunker is five. The fiberglass chute is suitable for processing 0.6-0.03MM and vein ores as well as minerals, but it is unfavorable for sorting when the mud content is high. It is now widely used for processing iron ore, tungsten, sand tin, tantalum niobium ore, bay and riverbed ore sand or placer gold, and so on.
