PULVERIZER 500 Planetary ball mill consists of a grinding platform and a clump weight on the same sun wheel. When the machine is powered on, bowl revolves around the sun wheel axis and rotates itself at the same time, which is called planetary motion. In high speed rotation, balls and samples in the bowl impact and clash each other intensively to achieve the crushing, grinding or emulsifying.
