For some polymers, the structure of the particles requires cryogenic grinding—a process by which the polymer pellets are chilled, decreasing heat buildup and adverse chemical reactions when pushed through the attritor. Without the use of cryogenic grinding, certain materials would melt, oxidize or discolor.

Polysulfone (PSU) has been processed into powder form by ball milling, rotor milling, and spray drying technique in an attempt to produce new materials for Selective Laser Sintering purposes. Both rotor milling and spray drying were adept to make spherical particles that can be used for this aim. Processing PSU pellets by rotor milling in a three-step process resulted in particles of …

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.
