Abstract

The invention relates to a coal mine crusher and belongs to the technical field of coal mine crushing devices. A wheel type crusher changes a movable hammer head into a fixed hammer head, the hammer head is in rigid connection with a rotating disc (or called a hammer seat) through threads, crushing on coal is realized adopting an impacting and extruding method, the crushing operation takes a lot of energy, impact and friction generated in the material crushing process will cause serious damage to machine parts, and meanwhile, the crushing operation will further cause dust hazard. By means of the coal mine crusher, the traditional method of crushing the coal by impacting is canceled, a grinding method for crushing the coal is adopted instead, compared with the impacting method, the grindingmethod will not cause great damage to a grinding device, meanwhile, the coal mine crusher is internally provided with a dust removal air fan, dust inside the crushing device is removed by the air fanand a filtering device inside the air fan, and the health of operators is guaranteed.

Description

technical field [0001] The invention relates to a coal mine crusher, which belongs to the technical field of coal mine crushing devices. Background technique [0002] Coal is the main component of my country's energy, and it is also one of the important raw materials for industry. The production of coal plays a pivotal role in my country's national economy. At present, blasting mining (referred to as blast mining) and mechanized mining are commonly used in domestic coal mining technologies. Almost all coal mines with conditions use comprehensive mechanized equipment for coal mining. The process of comprehensive mechanized coal mining mainly includes: coal breaking, coal falling, coal loading, coal transportation, support and roof management and other processes. The specific implementation of the coal mining process is realized through different equipment. The drum of the coal mining machine realizes the process of coal breaking, coal falling and coal loading in the coal min...
