Mineral sorting device, mineral processing production system and mineral sorting method

Abstract

The invention relates to a mineral sorting device, a mineral processing production system and a mineral sorting method. The mineral sorting device comprises a raising part used for colliding with falling minerals, and a mineral falling space is formed in the mineral sorting device. The raising part is arranged in the mineral falling space and can move. Inventively, during mineral sorting, the falling minerals collide with the moving raising part, and it is guaranteed that the minerals can be fully scattered and subjected to effective dust raising through the mechanical collision effect and the mineral stirring effect of the moving raising part; and good conditions are created for work such as screening and dust removal of the mineral sorting device so that the sorting effect of the mineral sorting device can be remarkably improved, and the quality of mineral sorting work is improved.

Description

technical field [0001] The present invention relates to a mineral processing equipment, in particular to a mineral sorting device and a mineral processing production system including the mineral sorting device. In addition, the present invention also relates to a mineral separation method. Background technique [0002] Minerals (such as building stones, metallurgical ores, etc.) need to be processed after mining to meet the requirements of use, and the sorting of minerals is an important work in the subsequent processing of minerals. Generally speaking, after the mineral is mined, unless the mineral itself is relatively broken, the mineral can be crushed by a crusher (such as a centrifugal crusher) to form a crushed mineral material, which contains a variety of particle sizes. of ore particles. [0003] As mentioned above, in order to meet different application needs, mineral sorting is an important task in mineral processing. It mainly divides minerals into materials of v...

Problems solved by technology

[0005] But, there is comparatively obvious shortcoming in above-mentioned mineral sorting device of prior art:

[0006] First, through the air supply mechanism to separate the input minerals by wind, a large air volume is required to blow the minerals, which leads to excessive energy consumption

Moreover, this technical means of wind separation cannot realize the effective dispersion of minerals at all. During actual use, it is found that there are still more ore particles with smaller particle sizes mixed in the larger ore particles, which leads to the failure of the mineral separation device. The sorting effect is very unsatisfactory

In particular, if there are agglomerates of ore particles with different particle sizes in the minerals, it is even more difficult to achieve effective separation of minerals

[0007] Second, in addition, in this prior art, minerals fall directly on the screen, which will form a greater impact on the screen, which will easily cause damage to the screen surface, greatly reducing the service life of the screening mechanism
