Spiral chute efficiency

Efficiency of spiral chutes: 1. Explain the requirements for fineness of spiral chutes. Gravity beneficiation is widely used in the beneficiation of metal and non-ferrous metals due to its small environmental pollution and low cost. Fiberglass reinforced plastic chute is one of the gravity separation equipment, with a structural characteristic that the cross-section is in a cubic parabolic state, suitable for handling finer particle sizes of -0.2MM. During the sorting process, no flushing water is required, and the fine, medium, and tailings are segmented at the tail of the chute. 2、 The principle of using spiral chutes in production is that the evenly proportioned mortar is slowly fed onto the rotating groove surface through the feeding chute installed on the spiral groove head for sorting. The tail end of the spiral groove is equipped with a valve type product acquisition groove, and the selected equipment is divided into three types according to grade along the radial direction. By adjusting the orientation of the valve block to change the cutting width of each product, the equipment gathering hopper allows the selected variable mineral flows to converge and export differently. The transverse plane and slope of the curve of the fiberglass spiral chute vary greatly, and the applicable range is for the selection of fine particle materials. Spiral chute efficiency. 3、 Due to its low power consumption, simple structure, small footprint, easy operation, stable beneficiation, clear separation, no need for moving parts, convenient maintenance and management, and high output per unit area, fiberglass chute has attracted special attention among various gravity beneficiation machines. The machinery has a relatively wide and stable groove surface, and the mineral mortar exhibits a large area of laminar flow, making it more suitable for processing medium to fine (-4mm) sized ores. We have made spiral chutes with diameters of 400, 600, 900, and 1200 millimeters domestically, Ф The processing capacity of 1200MM four head is about 4-6 T/H. The efficiency of the spiral chute is , and the re selection process of the spiral chute is composed of six parts: a feeding homogenizer, a feeding groove, a rotating groove, a product cutting groove, an equipment gathering bucket or a groove support (including a cross or triangular frame), etc. The spiral groove connected by the spiral plate is the main component. The rotating plate is made of fiberglass (fiber reinforced coal gangue), which is connected together through screws. The selected surface of the rotating groove has a predetermined wear-resistant layer. It also has the advantages of lightweight, sturdy, and durable consumer goods. Above the spiral groove, there is a multi tube feeding homogenizer for ore dressing and averaging, with simple control. The mineral screening device is freely placed on a cross (or tripod) on a support table. The evenly distributed mortar is slowly fed to the rotating groove surface by installing it on the feeding groove at the end of the spiral groove head, and sorting is carried out. The tail end of the spiral groove is installed in a valve block type new product acquisition groove, and the selected new products are divided into three categories (or four categories) 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 intercepted variable mineral flows to be gathered and exported separately. The cross section and slope of the curve of the spiral concentrator are particularly suitable for the separation of fine ore materials. 5、 The installation diagram of the rotating spiral chute in the field is used. The spiral concentrator is suitable for processing 0.6-0.03MM and vein ores and minerals, but it is unfavorable for separation when the mud content is high. Currently, it has been widely used for processing iron ore, tungsten, tin ore sand, tantalum niobium, bay and riverside ore and placer gold. Spiral chute efficiency Spiral chute efficiency
