TECHNICAL FIELD
[0001] The utility model relates to the technical field of ore dressing, especially a regulating device of a grading desliming feeding flotation machine. BACKGROUND
[0002] In the ore dressing technology, ore dressing is the process of separating useful minerals from gangue minerals to the maximum extent to obtain high-grade concentrates; the process of recovering as much as possible the symbiotic useful minerals into separate concentrates, removing harmful impurities, and comprehensively recovering and utilizing various useful components. Classification operation plays an important role in the grinding cycle. The purpose of classification operation is to make the useful minerals and gangue minerals or different useful minerals in the ore achieve single liberation or to make the particle size of the material meet the requirements of the separation operation. The classification operation often uses a hydrocyclone.
[0003] A hydrocyclone is a classification device that uses centrifugal force to accelerate the settling of ore particles. In the rotating water flow, particles are separated according to the difference in radial velocity. Coarse particles receive a large centrifugal force and are distributed on the outside, while fine particles receive a large centripetal force from the water flow and are distributed on the inside, achieving classification. The working principle of the hydrocyclone is that the ore pulp enters the shell along the tangent direction of the cylinder under the action of pressure, rotates in the shell, and the coarse particles (or particles with high density) in the ore pulp enter the outer periphery of the rotating flow due to the large centrifugal force and flow downward with the ore pulp, eventually being discharged from the bottom sand nozzle as sand; fine particles receive a small centrifugal force, are in the center of the rotating flow, and move upward with the liquid flow, and are finally discharged from the overflow pipe as overflow.
[0004] The underflow after classification operation is transmitted to the flotation machine for flotation operation. Flotation operation is the operation of separating the liberated useful minerals from gangue minerals (or different useful minerals). The existing hydrocyclone has a fixed height of the support frame at the bottom, so the height of the cyclone cannot be adjusted. Since the cyclone needs to be connected to other equipment through a pipe, if the cyclone is placed at a high or low position, it will increase the difficulty of connecting to other equipment, especially when connecting to the flotation machine.
