Bilateral rotating superfine grinding ball milling apparatus

The utility model relates to a bilateral rotating superfine grinding ball milling apparatus, which comprises a barrel body, a cavity formed by the barrel body and an inner lining plate arranged in the barrel body. An inner rotating shaft which rotates in opposite direction to the barrel body penetrates through the cavity and the cover plate of the end surface of the barrel body, and the inner rotating shaft in the cavity is provided with a stirring device. Outer barrel supporting members connected with the cover plate of the end surface are symmetrically arranged on the inner rotating shaft outside the cavity, and outer barrel supporting bearings matched with the outer barrel supporting members and the a driving device which drives the barrel body to rotate are respectively arranged on the outer barrel supporting member. An inner rotating bearing and a drive device of the inner rotating shaft are arranged in sequence between the outer barrel supporting member and one end of the inner rotating shaft outside the cavity. The utility model has the conspicuous advantages that only a reverse rotating stirring device is additionally arranged in the general horizontal type ball mill barrel body, so the utility model has simple structure and is easy to achieve. Because the reverse rotation of the reverse rotating stirring device increases the effective grinding area between balls, the cost is reduced effectively and the productivity is increased.
