  • Comminution device
    Patent number: 4063687
    Abstract: 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. The rotary support is a flexible wire rope which permits limited radial movement of the crushing mass, allowing centrifugal force to aid the comminution. The crushing mass is mounted at about the midpoint of the wire rope, allowing gyroscopic forces to further assist the comminution.
