The classic F series mixing machines which adopt the mobile material cylinder are applicable for the mixing and stirring of various powders and granules. After the cylinder containing the raw materials to be mixed is pushed to the workstation, the automatic control system lifts it, and securely locks it with the stirring head. The hopper is flipped 180° together, and the material stirring and mixing are completed under the effect of the stirring and crushing wheels. After completion of mixing, the hopper tilts and flattens the materials in a reverse direction, also has the functions of shaking wings for unloading. The entire process adopts PLC/HMI automatic control, and realizes even mixing and high production efficiency without generating solidified granules.
