Spiral chute selection for dust removal

Spiral chute dust removal: 1. Introduction: Gravity beneficiation is widely used in metal and non-metallic ore beneficiation due to its small environmental pollution and low cost. The fiberglass chute is one of the gravity separation equipment, with a structural feature of a cubic parabolic cross-section, suitable for handling finer particle sizes of -0.2mm. During the sorting step, there is no need to add flushing water, and the fine, medium, and tailings are segmented at the bottom of the chute. 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. spiral chute separation dust removal ash III. Characteristics This product is suitable for separating fine materials with a particle size of 0.3-0.02mm to get iron ore, ferrotitanium ore, chromite ore, pyrite ore, zircon sand, Rutile, monazite, phengite, tungsten sand, sand tin, tantalum, tantalum niobium and other non-ferrous metal ores, rare metals and non-metallic ore bodies with different densities and specific gravity. This equipment also has stable and easy to operate selection processes, a wide range of allowable changes in feed density, high enrichment ratio, high recycling rate, small land occupation, low water consumption, simple structure, no need for power, strong processing ability, easy installation, easy operation, low investment, and quick effectiveness. The spiral chute is composed of six parts: a feeding homogenizer, a feeding chute, a spiral groove, a equipment selection groove, a product gathering hopper, and a groove bracket (including a cross or triangular frame). The rotating groove connected by spiral blades is a key component. The rotating plate is made of fiberglass (fiber reinforced coal gangue), connected together by screws, and the spiral groove has a pre made wear-resistant layer on the selected surface. She has the advantages of being lightweight, sturdy, and durable consumables that are not easily damaged. Above the rotating groove, there is a multi tube feeding homogenizer for ore separation, which is simple and convenient to control. The sieving mineral containers are freely stacked on the cross (or tripod) of the support table. The evenly distributed mortar is slowly fed onto the surface of the rotating groove through the feeding groove installed at the head of the spiral groove, and sorting is carried out. The tail end of the spiral groove is equipped with a valve block type new equipment to obtain the groove. The selected new products are divided into three categories (or four types) according to grade along the radial direction. Change the cutting width of each new equipment by adjusting the orientation of the valve block. The new product gathering bucket is a concentric circular tube that allows the selected multiple ore streams to converge and lead out separately. The slope change of the cross-section and curve of the spiral concentrator is very suitable for the separation of fine particle materials. 5、 The fiberglass chute used in the field can be adapted to the separation of fine iron ore, Ilmenite, Chromite, pyrite, tin ore, tantalum niobium ore, placer gold, coal mine, monazite ore, Rutile ore, zircon ore, rare earth ore and other metal and non-metallic mineral materials with sufficient Density contrast.
