Beschreibung
Zusammenfassung:	Pulverisation appts. comprises >=1 pair of counter-rotating toothed rollers which rotate at different speeds and have their teeth tipped with hard metal. The faster moving roller has the leading edges of its teeth tipped whilst the other roller's teeth are tipped on their trailing edge. The teeth shanks are cylindrical and mounted in corresponding apertures in the rollers so as to define helical rows. Used with domestic or industrial waste, the appts. has low energy requirements.
