To obtain the running consistency of the four mill containers, gear drive is used. Four small identical-sized gears distribute evenly around a big gear and the modulus of all the gears are same, but the teeth numbers of the big gear are two-fold that of the small gears, and they configure together into a planetary gear train carrying out the revolution and rotation demand. For it's a vertical ball mill whose electromotor also needs vertical structure, its electromotor is fixed on its shell, and the electromotor transfers the torque to planetary gear train through belt drive,then drives the mill container rotation through the planetary gear train. Additionally, the shell is fixed on its pedestal with bolts, when the machine is running, the working part is covered with a mantle.
