There are many types and sizes of coal crushers on the market, most of which use the inertia of heavy objects or machine blades to crush coal, which generally has the disadvantages of complex structure and high energy consumption, and these coal crushers are faced with Large pieces of coal are prone to jamming due to the small output of the crushing device
[0003] At the same time, the traditional crusher does not have a graded crushing structure, and there will be uneven crushing and jamming, which seriously affects the crushing of coal blocks. At the same time, due to the high moisture content of some coals, it may adhere to the crushing mechanism and affect the crushing. Effect

Abstract
The invention discloses a coal briquette crusher for a coal mine. The coal briquette crusher comprises supports, a shell, a feeding hopper, a dividing block, feeding inlets, side blocking blocks, upper crushing rollers, upper connecting shafts, lower crushing rollers, lower connecting shafts, upper driving motors, lower driving motors, a power box, an air-blowing pump, branch pipes, fixing pipes,nozzles, guiding blocks, a discharging outlet, a falling cavity, a transport motor, a driving belt pulley, conveying rollers, a driven belt pulley, an outer cover shell, upper air-suction pipes, air-suction discs, a conveying belt, lower air-suction pipes, a filter shell, a filter screen, an air-guiding shell, an air-suction pump, a gas transmission pipe, a water tank, an upper blocking block andsupport rods. The coal briquette crusher is reasonable in structure design, through the two upper crushing rollers and the two lower crushing rollers, coal briquettes are secondarily crushed, that is,the large coal briquettes are first crushed into medium-sized coal briquettes, and then the medium-sized coal briquettes are crushed into small coal briquettes, so that the crushing effect is good, the good crushing effect is achieved through the simple structure, and meanwhile, jamming can be further avoided.
Description
technical field [0001] The invention relates to a crusher, in particular to a coal block crusher for coal mines, belonging to the technical field of coal mine equipment applications. Background technique [0002] In the industrial application of raw coal, coal gangue seriously affects the unit calorific value of coal, and the coal gangue in the coal raw material needs to be removed before industrial application of coal. The common practice now is to crush the coal block, process the coal raw material crushed to meet the standard, and separate the coal gangue. There are many types and sizes of coal crushers on the market, most of which use the inertia of heavy objects or machine blades to crush coal, which generally has the disadvantages of complex structure and high energy consumption, and these coal crushers are faced with Large pieces of coal are prone to jamming because of the small output of the crushing device. [0003] At the same time, the traditional crusher does n...
