The research team instead put commercial polystyrene inside a ball mill. When the device is turned on, it shakes, and small metals balls inside smash against the polystyrene pieces, facilitating chemical transformations. The team found that ball-milling broke the molecular chains– called polymers– into chains that were 10-20 times shorter.

Working Principle Planetary Ball Mill has four ball grinding tanks installed on one turntable. When the turntable rotates, the tank axis makes planetary movements, the balls and samples inside the tanks are impacted strongly in high speed movement, and samples are eventually ground into powder.Various kinds of different materials can be ground by the mill with dry or wet method.
