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.
Claims6
Material processing apparatus comprising:
- a. a mass having a first central longitudinal axis and having an outer surface,
- b. a chamber having a second longitudinal axis parallel to said first axis and having an inner surface of contour conforming axially substantially to that of said outer surface,
- c. rotary support means rotatable about said second axis and supporting said mass for free rotation about said first axis and for contact of said outer surface with said inner surface,
- d. drive means for rotating said rotary support means to rotate said mass around said inner surface,
- e. said rotary support means including a pair of longitudinally spaced apart support arms, a flexible wire rope extending along said first axis between said support arms, means rotatably journaling one end of said rope in each support arm for rotation of said wire rope about said first axis, and means mounting said mass on said rope approximately at the mid-portion of said rope, said rope thereby constituting a flexible axle supporting said mass and to enable tilting of said mass about said first axis, so that under rotation imparted by said drive means to said rotary support means, said mass will be impelled under centrifugal force generally radially outwardly of said rotary support means and will be pressed into contact with said inner surface of said chamber and will roll therearound, and so that said mass may tilt in the presence of a particle located between said outer surface of said mass and said inner surface of said chamber, thereby applying a crushing force constituted by both centrifugal and gryoscopic forces, against said particle.
