The invention provides an automatic feeding and discharging pulverized coal smashing device and a working method thereof. The pulverized coal smashing device comprises a smashing device body, an automatic feeding device, an automatic discharging device and a rack. The tail of the smashing device body is connected with the rack through a fixing frame, the automatic feeding device is connected to the position above the smashing device body, a feeding baffle is arranged inside the automatic feeding device, and automatic feeding of the pulverized coal can be controlled through rotation of the baffle; and the automatic discharging device is connected to the position below the smashing device body, a piston is arranged inside the automatic discharging device, a cylindrical curve face is arranged at the top of the piston and can be completely attached to the inner wall of a smashing cavity, and automatic discharging control over the pulverized coal is achieved through reciprocated sliding between the piston and a discharging pipe. By means of the device, automatic feeding and automatic discharging of the pulverized coal smashing device can be achieved, the automatic feeding and discharging pulverized coal smashing device is easily integrated into an automatic control system, and the operation efficiency is improved.
Description
technical field [0001] The invention relates to the field of pulverized coal crushing devices, in particular to a pulverized coal crushing device for automatic material feeding and discharging and a working method thereof. Background technique [0002] In the coal mining and sample preparation system, the coal powder must be graded and crushed to reach a certain particle size before sample preparation. In the final stage of crushing process, the coal powder needs to be crushed to a particle size of 0.2mm before testing. In the existing pulverized coal crushing equipment, most of the crushing process is manually fed, and after the crushing is completed, the materials are manually taken out. This method is inefficient, increases labor costs, and cannot fulfill automation integration requirements. [0003] According to the defects of the existing pulverized coal crushing equipment described above, it is necessary to develop a crushing device that can automatically feed and dis...
