ABSTRACT:
A machine for comminuting material by impact has a hollow impeller rotatable about a substantially vertical axis. The impeller has an upwardly opening material inlet and at least one radially outward material outlet. A tube serves to feed material to be comminuted into the material inlet. The lower portion of the tube rotates about its longitudinal axis and imparts an angular velocity to the material fed therethrough. Material entering the impeller travels along at least a portion of the interior walls of the impeller and on emerging from the impeller strikes an anvil where comminution occurs.
