The spiral chute for beneficiation 1 indicates that 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 method of use is to set up the spiral concentrator, calibrate the vertical line, fix the iron shelf or wood in the proper position, send the sand ore to the two ore feeding ports on the spiral top by the slurry pump, add water, adjust the density of the mineral slurry, the slurry naturally swirls from high to low, generate a single coherent centrifugal force in the flow speed of the rotating slope, and obtain the difference in the specific gravity, Granularity and state of the sand ore, Through the action of gravity and centrifugal force obtained through swirling flow, the sand and ore are separated, and the concentrate is discharged into the beneficiation hopper and connected out through pipelines. The tailings flow into the tailings hopper and are moved to the sand tank through pipelines, and then discharged by a sand pump, completing the entire beneficiation process. Mineral processing spiral chutes III. Features: Fiberglass reinforced plastic spiral chutes have attracted special attention in various gravity mineral processing machines due to their low power consumption, simple structure, small land occupation, simple operation, stable mineral processing, clear ore separation, no need for moving parts, easy maintenance and management, and large single area processing output. The machinery has a relatively wide and stable groove surface, and the area where mineral mortar flows in a laminar flow is huge. It is more suitable for processing medium to fine (-4mm) sized ores. Our country has produced spiral chutes with diameters of 400, 600, 900, and 1200mm, Ф The processing capacity of 1200MM four head is about 4-6 T/H. beneficiation spiral chute 4. The structure of the fiberglass spiral chute is composed of six parts: a feeding homogenizer, a feeding chute, a spiral chute, a product intercepting chute, an equipment gathering hopper or groove support (including a cross or triangular frame). The rotating groove connected by the rotating disc is a key component. The spiral plate is made of fiberglass (fiber reinforced coal gangue) and connected together by bolts. The sorting surface of the spiral groove has a pre made durable and wear-resistant layer. He also has the advantages of lightweight, strong, and durable consumables. The head of the rotating groove is equipped with a multi tube feeding homogenizer to sort minerals evenly, which is easy to control. The ore separator is not restricted from being placed on the cross (or tripod) of the support table. The evenly distributed mortar is slowly fed onto the surface of the rotating groove through a feeding groove installed at the end of the spiral groove head, and selected for operation. The tail end of the spiral groove is installed in a valve block type new product selection groove, allowing the sorting equipment to be divided into three types (or four types) of new products along the radial direction according to grade. Change the acquisition width of each new product by adjusting the position of the valve block. The new equipment gathering bucket is a concentric circular tube that converges and leads out the intercepted multiple ore flows. The lateral plane of the spiral concentrator and the change in slope of the curve are particularly suitable for the selection of small particle ore materials. Scope of Application Glass fiber reinforced plastic spiral chute is used to separate fine grained iron ore, ilmenite ore, chromite ore, pyrite ore, sand tin, tantalum niobium ore, placer gold mine, coal mine, monazite, Rutile, zircon ore, rare earth ore or other metal and non-metallic mineral materials with enough Density contrast. beneficiation spiral chute
