Mineral sorting device and mineral processing and producing system

Abstract

The invention discloses a mineral sorting device and a mineral processing and producing system. A dust-removal ventilation passage of the mineral sorting device comprises a first dust-removal ventilation branch channel (13), and at least one layer inside a screen (7) is correspondingly matched with the first dust-removal ventilation branch channel (13) which extends in the inclination direction of the screen corresponding to the first dust-removal ventilation branch channel (13), and the lower side face of the first dust-removal ventilation branch channel (13) is the upper screening face of the corresponding screen (7) so that in the ventilation state, dust-removal ventilation air flow on the first dust-removal ventilation branch channel (13) can at least partially flow upwards in an inclined mode along the upper screening face of the corresponding screen. One part of the dust-removal ventilation branch channel is arranged along the upper screening face of the screen, so that in the working process, the dust raising effect on minerals by screen vibration is used for making dust be sufficiently raised, and then the dust-removal air flow flows upwards against the movement direction of the minerals on the screening face to achieve a good effect.

Description

technical field [0001] The invention relates to a mineral processing device, in particular to a mineral sorting device and a mineral processing system. 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 various sizes according to the requirements of screening particle size, so as to be applied to different occasions, such as Used as roadbed ...

AI Technical Summary

Problems solved by technology

[0005] However, this air supply mechanism of the prior art has a very limited effect on dust removal in the minerals. During the rapid decline of the minerals from the feed port due to their own gravity, the wind force of the air supply mechanism can only make the minerals to a certain extent. The separated minerals have not been fully dispersed and dusted, and the entrainment effect formed by the rapidly falling continuous mineral flow makes most of the dust in the minerals unable to escape smoothly and enter the dust collection device9

Therefore, the dust content of the minerals sorted by the mineral sorting device of the prior art is very high, and the quality of the sorted minerals is not ideal

In response to this situation, for a long time, technicians in the field of mineral processing have not found effective solutions, and even in order to reduce the dust content of minerals, special dedusting of minerals is carried out through an independent process before mineral sorting, which not only Increases the cost of mineral processing and increases the complexity of operations
