Spiral chute model 1. Description Spiral chute is a combination of the characteristics of gravity beneficiation spiral chute, glass fiber reinforced plastic spiral chute, shaking table and centrifugal gravity concentrator. After relevant scientific research organized by the Ministry of Metallurgy, and identification by the design, school, mine and other departments, it is recognized that the equipment has excellent performance, progress in sorting indicators, and has won the Scientific and Technological Research Achievement Award of the Ministry of Metallurgical Industry. It has been widely used in non-ferrous and Ferrous mines. This machine is suitable for sorting iron ore, ferrotitanium ore, chromite ore, pyrite ore, zircon, Rutile, monazite, phosphate ore, tungsten ore, tin, tantalum ore, niobium ore with a particle size of 0.3-0.02 mm and other non-ferrous metal ores, rare ore metals or non-metallic ore bodies with specific gravity differences. 2、 Use the method to erect the spiral chute, calibrate the vertical line, fix the iron frame or wood in the proper position, and let the mineral sand be sent to the two ore feeding ports above the spiral by the mortar pump, participate in water filling, adjust the density of the mineral sand slurry, and the mineral slurry naturally swirls from top to bottom, generating a single coherent centrifugal force in the rotating slope flow speed, which is distinguished by the specific gravity, Granularity and state of the placer, By separating the ore and sand through the gravity of the swirling flow and the effect of this centrifugal force, the selected ore flows into the concentrate hopper and is piped out. The tailings are discharged into the tailings hopper and moved to the sand tank through a pipeline, and then discharged by a slurry pump, completing the entire beneficiation process. Spiral chute model III. Features This machine is suitable for separating fine materials with Granularity of 0.3-0.02MM to obtain iron ore, Ilmenite, ferrochrome, ferrosulfide, zircon ore, Rutile ore, monazite ore, phosphate ore, tungsten ore, tin ore, tantalum niobium ore, tantalum niobium ore or other non-ferrous metals, rare mineral metals and non-ferrous metal mineral bodies with different density and specific gravity. This machine also has the advantages of stable sorting process, simple control, wide range of allowable changes in ore concentration, high enrichment ratio, high recovery probability, small area occupation, low water consumption, simple structure, no power required, strong processing capacity, simple installation, simple operation, low investment, and quick effectiveness. Model 4 of the spiral chute. The structural composition of the fiberglass chute is composed of six parts: a feeding homogenizer, a feeding groove, a rotating groove, an equipment cutting groove, a product gathering hopper, and a groove bracket (including a cross or triangular frame). The spiral groove formed by the connection of spiral plates is a key component. The rotating plate is made of fiberglass (fiberglass reinforced coal gangue) and is bolted together. The selected surface of the rotating groove has a pre designed durable wear-resistant layer. It has the advantages of being lightweight, sturdy, durable, and not easily damaged consumer goods. The spiral groove is equipped with a multi tube feeding homogenizer to divide ore evenly, making it easy to operate. The concentrator is not limited to being placed on the cross (or tripod) of the support table. The evenly divided mineral mortar is slowly fed onto the spiral groove surface through the feeding chute at the head of the rotating groove for sorting. The tail of the rotating groove is installed in a valve type new product selection groove, and the selected new products are divided into three types (or four types) of new equipment along the radial direction according to grade. Change the width of each new product by adjusting the position of the valve block. The new product gathering bucket is a concentric circular tube that allows the intercepted multi-directional mineral flow to converge and lead out. The cross section of the spiral chute and the different slopes of the curves are very suitable for sorting fine particle materials. Spiral chute model V. Application field: FRP chute is suitable for separating fine iron ore, ilmenite ore, chromite ore, pyrite ore, placer tin ore, tantalum niobium ore, placer gold mine, coal mine, monazite ore, Rutile ore, zircon, rare earth ore, and has enough density ratio difference to get other metal and non-metallic minerals.
