Spiral chute Separation principle Spiral chute Separation principle I. Equipment overview A gravity concentrator that uses the continuous centrifugal force generated by the slurry in the spiral rotation movement to separate light and heavy minerals. 2、 By using a method, the spiral chute is erected and aligned with the vertical line. An iron frame or wood is used to position it in a suitable position. The sand and ore are pumped by a slurry pump to the two feeding ports above the spiral, where water is added and the density of the mineral slurry is adjusted. The slurry naturally swirls from high to low, generating an inertial centrifugal force in the swirling slope flow velocity. The difference is based on the specific gravity, particle size, and state of the mineral sand, By utilizing the gravity and centrifugal force of the swirling flow, the sand and ore are separated. The selected ore enters 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 mortar pump, completing the entire beneficiation process. Separation principle of spiral chute III. Features and highlights 1. Heavy duty and large processing output. In principle, contemporary mineral aggregate processing needs to create benefits through economies of scale. 2. Fine granulation is used for the treatment of fine particle minerals, especially for the treatment of mineral materials with a particle size of -0.047mm. Originally, the machine could basically ensure the recovery of particles with a particle size of+0.047mm. 3. With the development of Hydraulics, two-phase flow, mechanical vibration, etc., GRP chutes have developed from the simple use of gravity and water blocking force to the composite application of centrifugal force, equipment vibration force, magnetic separation force, etc. By using a composite force field, the enrichment of applicable minerals is enhanced and the separation of fine and micro particles is achieved, thereby increasing the recovery rate of mineral materials. 4. Based on energy saving, environmental protection and consumption reduction, the land area, space, water and electricity consumption should be small. 5. Simple and flexible operation, stable selection steps, simple structure, and convenient maintenance management. Separation principle of spiral chute IV. Structure composition The FRP chute is composed of six parts: feed leveler, feed chute, rotary chute, equipment acquisition chute, product gathering hopper or slot support (including cross or tripod). The spiral groove formed by connecting spiral pieces is the main component. The rotating plate is made of fiberglass (fiberglass reinforced coal gangue), which is connected together through screws. The selected surface of the rotating groove has a pre designed durable anti wear layer. It also has the advantages of lightweight, sturdy, and long-lasting consumer goods. The head of the spiral groove is equipped with a multi tube feeding homogenizer for screening ore, which is simple to operate. The mineral separator does not need to be restricted to placing on a cross (or tripod) on a support table. The evenly distributed slurry is slowly fed onto the spiral groove surface through a feeding chute installed at the head end of the rotating groove, and sorting is carried out. The bottom of the rotating groove is installed in a valve block type new product cutting groove, and the selected new equipment is divided into three (or four) types of new products according to grade along the radial direction. Change the width of each new product by adjusting the position of the valve block. The new equipment gathering bucket is a concentric annular tube that allows the selected variable ore flows to be densely exported. The transverse surface of the fiberglass spiral chute and the slope of the curve change, which is particularly suitable for the separation of small particle mineral materials. 5、 This equipment is suitable for separating iron ore, Ilmenite, Chromite, pyrite, zircon, Rutile, monazite, phosphate ore, tungsten ore, placer tin, tantalum, tantalum niobium ore and other nonferrous metal ores, rare ore gold and non nonferrous metal mineral bodies with specific gravity difference from fine materials with Granularity of 0.3-0.02MM.
