For the sample preparation for the RoHS  analysis, several steps are necessary in order to achieve the desired degree of fineness. Optimal here are FRITSCH Mills. 

Considering the characteristics of materials used for the construction of a cell phone the whole spectrum of hard-tough to hard-brittle up to soft, tough-elastic materials is found. Mentioned should be metals, ceramic parts and the most various plastics.

Whereas the hard-brittle materials are easily ground with impact energy, the comminution of tough-elastic materials is only achieved with cutting force. Tough-elastic materials may be embrittled with liquid nitrogen and then ground with impact force.
