Abstract

The invention discloses a multistage crushing device of coal. The multistage crushing device comprises a bottom plate, wherein a box body is fixedly connected to the top of bottom plate, a rectangularbox is fixedly connected to the top of one side of the box body, a protective housing is fixedly connected to one side of the top of box body, a supporting plate is fixedly connected between the twosides of the internal wall of the box body, a mounting box is fixedly connected to one side of the bottom of the supporting plate, a first motor is fixedly connected to the bottom of the internal wallof the mounting box, a rotating device is fixedly connected to one end of an output shaft of the first motor and comprises a fan plate, and one side of the fan plate is fixedly connected with one endof the output shaft of the first motor. The invention relates to the technical field of coal production. According to the multistage crushing device of the coal, the coal can be rapidly and efficiently crushed and extruded, and coal of relatively large sizes can be thoroughly crushed, so that the multistage crushing device is time-saving and labor-saving and simple in operation, the efficiency ofcrushing is increased, and much unnecessary cost is reduced.

Description

technical field [0001] The invention relates to the technical field of coal production, in particular to a multistage coal crushing device. Background technique [0002] Coal pulverizer is called coal crusher for short, and it is one of the commonly used equipment in the crushing coal and coal gangue production line. The coal pulverizer is improved on the basis of the old hammer crusher. Machine, this coal pulverizer is mainly aimed at the special model used for pulverizing coal in coal washing plants, brick factories, etc. This model solves the problem that the material has a high moisture content and is easy to block when pulverized, because the coal pulverizer is designed without The sieve bottom and screen mesh, so even if the moisture point of the material is large, there will be no clogging, and normal production can be carried out even in rainy days. In addition, although the coal pulverizer does not have a sieve bottom, it uses upper and lower two-stage rotors for cr...
