DETAILED DESCRIPTION OF IMPLEMENTATION OPTIONS

[16] In order to solve the above problem and achieve the above effect, the features and functions of the preferred embodiments of the present invention are illustrated in detail using the technical means and structures used in the present invention, in combination with the accompanying drawings.

[17] As shown in FIG. 1-2, the present invention provides a double-station, drum-type ball mill comprising a frame 1, wherein support bases 8 are provided on a lower portion of the frame 1; a driving roller 3 and two driven rollers 2 are provided side by side on an upper portion of the frame 1, wherein the two driven rollers 2 are distributed on both sides relative to the driving roller 3 to form double stations, and an electric motor 7 is provided in the frame 1 for driving the driving roller 3 into rotation; further, it comprises a rotating device 5, wherein the rotating device 5 comprises a supporting rod 53, supporting plates 54, and a driving mechanism 52 for activating the supporting plates 54 to rotate them up and down; wherein the supporting rod 53 is provided in the frame, under the driving roller 3 and perpendicular to the driving roller 3; two support plates 54 are provided which are distributed between the driving roller 3 and two driven rollers 2, at each of the two ends of the upper part of each of the support plates 54 two universal wheels 55 are located, in the middle of the lower part of each of the support plates 54 a first plate 56 with an eye is located, wherein through holes are made in the first plates 56 with an eye into which a support rod 53 is seated, and also the support plates 54 are connected with the possibility of rotation to the support rod 53 by means of the first plates 56 with an eye; the drive mechanism 52 can be a telescopic element, such as a hydraulic cylinder, an air cylinder or an electric drive; and at one end of the lower part of each of the support plates 54 near the drive mechanism 52 there is a second plate 57 with an eye, a power rod 58 is inserted into the through holes of the second plates 57 with an eye with the possibility of rotation, a third plate 51 with an eye is located in the frame 1, wherein the lower part of the drive mechanism 52 is pivotally attached to the third plate 51 with an eye, and the upper part of the drive mechanism 52 is fixedly connected to the middle part of the power rod 58.

[18] During operation, materials and grinding balls are placed in the ball grinding tank, and then the ball grinding tank is arranged horizontally between the driving roller 3 and the driven rollers 2. Two driven rollers 2 are provided, so that two ball grinding tanks can be arranged, thereby improving the working efficiency. The electric motor 7 is started to drive the driving roller 3 to rotate, thereby driving the ball grinding tank to rotate to perform grinding. At the same time, the drive mechanism 52 is extended to activate the support plates 54 to rotate them, taking the support rod 53 as the center. In the process of rotation, the universal wheels 55 on the support bases 54 can support one end or the other end of the ball grinding tank to tilt the ball grinding tank to change the positions of the materials at the two ends of the ball grinding tank, thereby improving the mixing effect.
