[0021] The mounting assembly 9 includes a rib 91 fixed on the surface of the rotating shaft 6, and a rib groove 92 matched with the rib 91 is opened inside the mounting sleeve 7. The arrangement of the rib groove 92 and the rib 91 facilitates the bolt 94 to be located on the same straight line as the threaded hole 95. A blocking rod 93 is fixed on the surface of the rotating shaft 6 to block the mounting sleeve 7. The limiting position of the blocking rod 93 allows the bolt 94 to be quickly aligned with the threaded hole 95. The surface thread of the mounting sleeve 7 is penetrated by the bolt 94, and the surface of the rotating shaft 6 is fixed with a threaded hole 95 matched with the bolt 94.

[0022] The blowing assembly 10 includes an annular tube 101 fixed on the inner wall of the pulverizing chamber 1, and a plurality of jet pipes 102 are connected above the surface of the annular tube 101. A one-way valve 103 is fixed on the surface of the jet pipe 102. The one-way valve 103 is set to prevent the powder material from entering the annular tube 101. An air pump 104 is fixed to the outside of the pulverizing chamber 1, which is electrically connected to an external power supply and controlled by a control switch. The air outlet of the air pump 104 is connected to a conduit 105, and one end of the conduit 105 passes through the pulverizing chamber 1 and is connected to the surface of the annular tube 101.

The crushed raw material is retained under the grinding chamber 1. After the processing is completed, the air pump 104 can be started, and the air flow enters the annular tube 101 through the conduit 105 and is ejected through the jet pipe 102.
