Embodiment Construction

[0010] The present invention will be further described below in conjunction with the embodiment in the accompanying drawings:

[0011] The impact type coal gangue crushing and separating test machine of the present invention includes a mechanical part and a control part.

[0012] The mechanical part includes a belt conveyor and a drum accelerated crushing device. The drum accelerated crushing device includes a drum shell 2, an auxiliary crushing block 3, and an accelerating runner 4. There is a material ejection port 9 on one side of the shell, and the accelerating runner 4 passes through the connecting The shaft 5 is connected with the variable frequency speed regulating motor 7, the connecting shaft 5 is fixed by the fixed frame 6, the motor 7 is fixed on the casing 2 by rubber soft 8 sets, the material is transported into the casing 1 by the belt conveyor 1, and falls on the acceleration On the runner 4, the acceleration runner 4 rotates at an accelerated speed driven by th...

Abstract

A reaction type gangue crushing and separating tester comprises a belt conveying portion and a roller accelerated crushing portion; the belt conveying portion is a conventional belt conveyer portion; the roller accelerated crushing portion comprises a housing, an accelerating wheel is mounted in the housing, the wall of the housing is provided with three auxiliary crushing blocks, the right side of the housing is provided with a material casting outlet, the accelerating wheel is controlled by a motor fixed in the housing, a reaction plate is arranged in the material casting direction, gangue is crushed by the reaction plate and drops on a vibrating screening mechanism that is inclined, and the gangue and pulverized coal are separated by the vibrating screening mechanism. A speed sensor is mounted on a rotary shaft of the tester, such that the tester can meet the need of a gangue separator for material conveying, allows the material casting speed to be controlled and adjusted, and is of certain testing study significance.

Description

technical field [0001] The invention relates to an impact-type coal gangue crushing and separation test machine, in particular to a crushing separator for underground coal and gangue separation. Background technique [0002] Coal gangue is a general term for rocks containing a certain amount of coal produced during coal mining. The general treatment is to pile up in the mining area, which not only occupies the area of ​​cultivated land, but also pollutes the environment, so the treatment of gangue outside the well is the focus of research on gangue treatment today. Because coal gangue contains a certain amount of coal, direct landfilling is a waste of resources, and landfilling after disposal of gangue is the main technology for underground disposal of gangue. Downhole gangue treatment technologies mainly include manual hand selection, winnowing, jigging sorting, and gamma ray sorting. Among them, manual selection: Firstly, it requires a lot of manpower, the labor intensit...
