Arc surface spreading flow film sorting machine

Abstract

The invention discloses an arc surface spreading flow film sorting machine, and relates to equipment capable of continuously sorting fine-particle refractory minerals under combined effect of gravity and turning force. The equipment mainly consists of a rotary sorting disc driven by a driving device, an ore and water feeding device and an ore receiving and discharge device; the upper surface of the sorting disc is a spherical arc surface with a curvature radius of 0.58-2.27 m; the outer edge of the spherical arc surface is connected with a lap of annular inclined surface for forming an angle of 3-8 degrees with the horizontal plane; a flushing water pipe is mounted on the annular inclined surface; an ore receiving groove below the sorting disc in the flushing water pipe is provided with middling, concentrate and tailing discharge ports in sequence at intervals; an ore separation flushing disc is arranged rightly above the sorting disc; the upper part of the disc is a conical surface fixed disc, and the lower part is a movable disc provided with a rotating shaft; an ore feeding pipe mouth and a water feeding pipe mouth are aligned to the fixed disc; a series of leakage holes are formed in the bottom of the fixed disc, and are aligned to the movable disc; and a series of baffle plates aslant dispersed are arranged on the surface of the movable disc. The machine is suitable for environment-friendly, efficient, energy-saved and continuous sorting of 0.2-0.037 mm fine-particle valuable minerals.

Description

technical field [0001] Technical field: The invention relates to a kind of mineral processing equipment that can continuously and autonomously sort wide-grained minerals with relative density differences under the combined action of gravity and gyration, and recycle them efficiently and environmentally friendly, especially suitable for minerals with a particle size of 0.2-0.037mm Separation of fine-grained valuable minerals arc-spreading flow-membrane separator. Background technique [0002] With the substantial increase of human demand for mineral products, the grade of selected ore has decreased year by year, the scale and intensity of mining of mineral resources have increased day by day, and the output of tailings has also continued to rise. Tailings are treasures waiting to be tapped. As of 2010, the tailings accumulation volume was about 11 billion tons. In 2010 alone, the tailings discharge volume was as high as 1.2 billion tons. A large number of tailings pools have ...

Problems solved by technology

However, the inventors found that the suspended vibrating conical concentrator is a mineral concentrator under the action of multiple compound force fields. It adopts two major motion systems of high-frequency vibration and rotation. The movement of the equipment is relatively complicated, and it is difficult to realize a multi-layered structure. Settings, limited room for improvement in processing power
