The perfect solution for these types of samples is cold or cryogenic grinding. This involves grinding aids such as liquid nitrogen (-196 C) or dry ice (-78 C) which embrittle the sample by cooling and make it break more easily. Another advantage is the preservation of volatile components of the sample.

Cryogenic grinding technology has been used in the waste recycling industry to produce rubber crumb since the early 1990s. The main advantage is that when liquid nitrogen (LIN) is used to cool the material to cryogenic temperatures, it becomes more brittle. This means that less energy can be used to easily break it into small particles.
