<p>A comminution device in which a crushing mass having an outer surface of helical configuration is mounted on a rotary support which rolls the crushing mass around the interior surface of a crushing chamber. The helical surface provides improved comminution. Preferably the rotary support permits limited radial movement of the crushing mass, allowing centrifugal force to aid the comminution, and preferably the support includes a flexible axle on which the crushing mass is mounted, allowing gyroscopic forces to further assist the comminution.</p> |
