When running the machine, push the mixing bin into rotary arm and tighten the nuts, then start the control system and lift the bin to the mixing height. Then, the control system starts mixing automatically according to the setting time and rotation speed, etc. When finish mixing, the material fixed in a horizontal position and the bin downwards to the ground automatically. After that, the whole machine stop and print process data. Finally, unfasten the locking nuts of rotary arm and move the bin out, and transfer it to the next process. As the symmetrical axes of bin and the rotating center line of rotating arm form an included angle, materials with different constituents are strenuously rolling over in the closed bin and producing high shear to achieve the best effect of mixing.
