Coal gangue separation equipment based on strength difference

Abstract

The invention discloses coal gangue separation equipment based on the strength difference. The coal gangue separation equipment based on the strength difference comprises a base and a charging barrel fixedly connected to the upper part of the base. A feeding hole and a discharging hole are formed in the upper end face and the lower end face of the charging barrel correspondingly; a rotating barrel is rotationally connected to the outer side of the circumference of the charging barrel; a hydraulic rod is fixedly connected onto the rotating barrel; the movable end of the hydraulic rod is fixedly connected with a moving plate; first grinding teeth are fixedly connected onto the side wall of the circumference of the charging barrel; fixing plates are fixedly connected onto the rotating barrel and the moving plate; second grinding teeth are fixedly connected onto the fixing plates and are matched with the first grinding teeth; blanking holes are formed in the fixing plates; the hydraulic rod is fixedly connected onto the rotating barrel; and the moving plate is fixedly connected to the movable end of the hydraulic rod. According to the coal gangue separation equipment based on the strength difference provided by the invention, coal raw materials are ground to form coal chippings and coal gangue, so that a separation effect is achieved, and convenience is brought to workers.

Description

technical field [0001] The invention relates to the technical field of coal gangue separation, in particular to a coal gangue separation device based on strength difference. Background technique [0002] Coal gangue is solid waste discharged during the coal mining process and coal washing process. It is a black-gray rock with low carbon content and high specific coal strength associated with coal seams during the coal formation process. Including the excavation gangue during the roadway excavation, the gangue extracted from the roof, floor and interlayer during the mining process, and the washed gangue picked out during the coal washing process. Therefore, it is necessary to separate the coal gangue from the mined coal raw materials. [0003] However, the existing coal gangue sorting equipment does not grind coal raw materials based on the characteristics of coal gangue. Due to the high strength of coal gangue, it cannot be ground into powder during the grinding process, and...

Problems solved by technology

[0003] However, the existing coal gangue sorting equipment does not grind coal raw materials based on the characteristics of coal gangue. Due to the high strength of coal gangue, it cannot be ground into powder during the grinding process, and the coal material is Coal debris will be formed during the grinding process, so the existing equipment generally does not have a grinding mechanism to sort the coal gangue, and it is also inconvenient to discharge the coal debris and coal gangue in batches after sorting. Inconvenience to the staff
