With cryogenic size reduction, Linde offers a process which economically pulverizes many different materials with low-temperature gases. This process can.

Cryogenic grinding - Wikipedia

Cyrogenic grinding, also known as freezer milling, freezer grinding, and cryomilling, is the act of cooling or chilling a material and then reducing it into a small particle size. For example, thermoplastics are difficult to grind to small particle sizes at ambient temperatures because they soften, adhere in lumpy masses and clog.

For which materials is cryogenic grinding advisable? Samples with elastic behavior. Many polymers (plastics such as PP, PET, PA, etc.), as well as other materials, show visco-elastic behavior during grinding which results in a plastic deformation. This means that a crack initiation - and thus a break-up - does not occur.
