Novel dressing machine

Abstract

The present invention discloses a novel dressing machine, comprising a milling machine and an ore dressing bunker, wherein, the ore dressing bunker is a hollow container, with feed port and feed pipe on the top, discharge hopper and fresh air inlet on the bottom, and a distributor in the bunker; the milling machine is connected to the ore dressing bunker through feed pipes, and each feed pipe is equipped with an induced fan; the discharge port of the feed pipe on the ore dressing bunker is right above the distributor. The feed pipe on the top of the ore dressing bunker is serially connected to a second ore dressing bunker. The milling machine mill dry ore into ore powder at 250-500 mesh size, and the blast fans and induced fans drive the ore powder to convey in the feed pipes. The distributor agitates the ore powder completely, to disperse the ore powder. Ore with high specific gravity drops to the bottom of the ore dressing bunker directly, while ore or foreign substances with low specific gravity are driven by the induced fan to enter into the next ore dressing bunker for further ore dressing. The dressing machine employs a pneumatic separation method, is free of pollution, can save water resource, and has high ore recovery rate.

Description

technical field [0001] The invention relates to a mineral processing equipment, in particular to a new type of mineral processing machine. Background technique [0002] At present, domestic iron ore mining and beneficiation enterprises mostly adopt the flotation method of adding water and chemicals. The disadvantages of this beneficiation method are: (1) a large amount of water resources are wasted; (2) a large amount of waste water will be generated, causing environmental pollution; (3) The cost of mineral processing is high; (4) The efficiency of mineral processing is low, which wastes ore resources. In addition, there are centrifugal force beneficiation methods and devices, magnetic beneficiation methods and devices, but these mining devices have complex structures, high production costs, and low beneficiation efficiency, resulting in waste of ore resources. Contents of the invention [0003] The object of the present invention is to overcome the deficiency of the mine...

[0002] At present, domestic iron ore mining and beneficiation enterprises mostly adopt the flotation method of adding water and chemicals. The disadvantages of this beneficiation method are: (1) a large amount of water resources are wasted; (2) a large amount of waste water will be generated, causing environmental pollution; (3) The cost of beneficiation is high; (4) The efficiency of beneficiation is low, which wastes ore resources

In addition, there are also centrifugal force beneficiation methods and devices, magnetic beneficiation methods and devices, but these mining devices have complex structures, high production costs, and low beneficiation efficiency, resulting in waste of ore resources.
