detailed description

In view of the deficiencies in the prior art, the utility model of the present invention has been able to propose the technical solution of the present invention through long-term research and extensive practice. The technical solution, its implementation process and principle, etc. will be further explained as follows.

An agitating ball mill according to this embodiment includes a frame 2, a mixing drum 4 fixed to the frame 2, a stirring assembly 8 located in the mixing drum 4, and a driving mechanism.
