These degrees of fineness can be achieved e.g. by grinding in a ball mill ,
preferably in the Retsch PM100; PM200; PM400; RS200 or MM400.
In most cases, particularly where hard materials are concerned, some wax powder
has to be mixed well with the ground sample before conducting the pressing
procedure.
