BLL testing spiral chute technical parameters
Technical Parameter of laboratory BLL Glass Fibre Reinforced Plastic Spiral Chute
BLL spiral chute is based on useful minerals and gangue minerals in proportion, size, shape differences, the pulp produced in the spiral movement of the slope centrifugal flow membrane, the centrifugal force of gravity and the integrated stand, the use of different particles suffered gravity, hydrodynamic pressure and friction to achieve the useful minerals in the gangue separation. Spiral slot except for the water moving downward spiral, but also for the horizontal circulation. The upper water flow faster, have a greater inertia centrifugal force, Shuaixiang the outer groove. Adjacent to the lower bottom water with slow rotation, centrifugal force is small, the gravity flow from the outer edge of the inner edge, resulting in secondary reflux. Pulp in the fast settlement of heavy mineral particles, along the gradual convergence of the inner edge of the spiral, and finally to concentrate in the form generated. Slow light mineral deposition, the surface flow in the mine, flow speed, centrifugal force, under sub-ah transverse circulation along the spiral gradually expanded gradually toward the outer edge of the final output in the form of tailings. This product is the only designated the former Ministry of Geology and Mineral production, the implementation of industry standards.
BLL spiral chute is based on useful minerals and gangue minerals in the specific gravity, particle size, shape differences in spiral bevel dynamic centrifugal flow of pulp produced film, in the consolidated position of gravity and centrifugal force, the use of different particles suffered by gravity, hydrodynamic pressure and friction to achieve useful minerals in the gangue separation. Spiral tank of water movement except for a downward spiral, but also for the horizontal circulation. The upper water flow faster, resulting in a larger centrifugal force, inertia, Shuaixiang the outer groove. And the bottom adjacent to the lower flow turning slow, centrifugal force is small, the gravity flow from the outer edge of the inner edge, resulting in secondary reflux. Pulp in the heavy mineral grains settling faster convergence along the spiral gradually inward edge of the end, the form of concentrates produced. Light mineral deposition slowly, at a surface mine flow, velocity fast, centrifugal force, sub-ah horizontal circulation under the effect of gradually expanded along the line gradually moved towards the outer edge of the spiral, the end, the form of tailings output. This product is the only designated former Ministry of Geology and Mineral production, the implementation of industry standards.
