Then, the storage barrel 3 is driven by the rotating rotating member 5 and cooperates with the supporting member 6 to drive the storage barrel 3 to rotate eccentrically in the grinding frame 2, which can not only drive the storage barrel 3 away from the contact with the grinding frame 2, but also adjust the position between the storage barrel 3 and the grinding frame 2 to ensure that the raw materials are quickly ground and processed. At the same time, the rotating grinding disc 13 can adjust the position of the raw materials in the storage barrel 3 to avoid the raw materials The position remains unchanged and affects the grinding efficiency.

[0024] The lifting assembly 9 includes a driving motor 91 fixed to the top of the fixed cylinder 7. The output shaft of the driving motor 91 passes through the inner cavity of the fixed cylinder 7 and is fixed with a screw 92 that rotates inside the fixed cylinder 7 through a bearing. A limiting groove 93 is vertically provided on the side wall of the fixed cylinder 7. The outer side of the screw 92 is threadedly connected to a threaded cylinder 94.
