Coal briquette crushing and screening machine for coal dressing

Abstract

The invention belongs to the technical field of coal mine devices, and particularly relates to a coal briquette crushing and screening machine for coal dressing. The coal briquette crushing and screening machine comprises a coal briquette crushing mechanism, a coal briquette screening mechanism and a control system; the coal briquette crushing mechanism is used for crushing coal briquettes, and the coal briquette screening mechanism is used for screening the crushed coal briquettes in size; the coal briquette crushing mechanism comprises a first crushing mechanism and a second crushing mechanism which are arranged in a mirroring manner, and connecting pieces for connecting the first crushing mechanism and the second crushing mechanism are arranged on the upper portions of the first crushing mechanism and the second crushing mechanism in a mirroring manner; and adjusting pieces for adjusting the distance between the first crushing mechanism and the second crushing mechanism are arranged on the lower portions of the first crushing mechanism and the second crushing mechanism in a mirroring manner. According to the technical scheme, the problems that a coal briquette crushing device is single in crushing specification, and a coal briquette screening device is incomplete in coal briquette screening specification, so that the coal briquettes need to be further treated in the subsequent using process are solved.

Description

technical field [0001] The invention belongs to the technical field of coal mine devices, and in particular relates to a coal crushing and screening machine for coal preparation. Background technique [0002] Whether it is domestic or industrial coal, it occupies an irreplaceable position, but the coal that has just been mined from the mine is large, and the large coal needs to be crushed. The crushed coal should be classified according to the size for daily use. Or industry. [0003] The pulverized coal lumps in the prior art coal crushing device are usually of the same specification and cannot be adjusted, causing the pulverized coal lumps to be further pulverized according to the usage conditions in the subsequent use. [0004] Existing screening devices used after coal mining still have certain defects in use. Because the volume of pulverized coal is generally uneven, ranging from large to small, the screening specifications are not comprehensive during screening, resul...
