Abstract

The grinding machine comprises a cylindrical grinding chamber (10) part of whose peripheral wall is formed by a perforated screen (11), a rotor (12) within a grinding chamber which pivotally mounts radially extending grinding hammers (15), an inlet duct (16, 17) which may be reversible for drawing air from the interior of the chamber through the screen to convey ground material from the chamber, and a baffle (18) disposed in the duct and movable between two positions. The two positions of the duct enable the material to be directed into the chamber, tangentially, either with or against the direction of rotation of the rotor. The grinding hammers may have surface portions which prevent impacting materials from re-entering the feed chute, thus avoiding choking.
