The main machine shell comprises a main machine shell side plate 13 and a main machine shell middle cylinder 14. The main machine shell side plate 13 is buckled with the main machine shell middle cylinder 14, and the main machine shell side plate 13 and the main machine shell middle cylinder 14 are fixed through a connecting piece 12. During work, the powder raw material enters the inside of the main machine shell through the feeding pipe, and the powder raw material is impacted, sheared and crushed with the stationary lining plate and the high-speed rotating impact disc. The classifier is provided with a classification wheel (not marked), the classification wheel is inserted into the right side of the inner wall of the main machine shell, the crushed powder particles reach the periphery of the classification wheel under the driving of the airflow, the classification wheel rotates at high speed to generate centrifugal force, the centrifugal force of the finer powder particles is small, and the finer powder particles are taken into the inside of the classification wheel and discharged under the driving of the airflow; the coarser particles are thrown to the inner wall of the main machine shell under the action of the centrifugal force of the classification wheel, the impact disc rotates at high speed to generate negative pressure, the coarser particles enter the impact disc and the lining plate again to be impacted and sheared and crushed under the joint action of the negative pressure and the airflow entering the air inlet volute, the crushed powder particles reach the periphery of the classification wheel again to be classified under the driving of the airflow, and the process is repeated. The structure, position and connection relationship of the main machine shell and the connecting piece are favorable for convenient maintenance. Since the impact hammer head and the lining plate inside the impact mill participate in the crushing of the powder raw material, the impact hammer head and the lining plate are consumable parts, and the service life of each consumable part is different. Under normal circumstances, the left hammer head and the lining plate are replaced frequently, and the right classification wheel is replaced less frequently. The main machine shell is provided in a split type, and the corresponding connecting piece and the corresponding side plate are opened according to the position of the consumable part during maintenance, so that the impact mill does not need to be disassembled as a whole, the maintenance is convenient, and the labor and time cost of maintenance is reduced.
[0031] In one embodiment, the impact mill convenient for maintenance further comprises a machine base 1 and a support 2.
