Abstract
A tooth is made from a casting of one material. The tooth includes a working surface having a first edge and a second edge. The first edge has at least three teeth. The second edge also has at least three teeth. The working surface is provided with a welded overlay or a hardfaced welded overlay. The tooth can be attached to a mount on a rotating drum. The tooth is removably attached to the drum so that when it wears it can be replaced with another tooth. The rotating drum is part of a fragmenting machine.
Claims17
A fragmentation apparatus comprising:
- a cylindrical drum having an outer surface with a plurality of spaced apart cutouts therein, the cylindrical drum configured to rotate in a rotational direction;
- a plurality of holders attached to the cutouts on the cylindrical drum;
- a plurality of mounts attached to the plurality of holders on the cylindrical drum, each holder positioned within a cutout;
- a tooth including:
- a main body, the main body including:
- an attachment surface attached to at least one of the plurality of mounts, the outer perimeter of the attachment surface defining a footprint for the tooth, the footprint bounded by the outer perimeter of the attachment surface;
- and
- a leading working surface formed as part of the main body, the leading working surface facing the rotational direction;
- a first edge having at least three cutting claws, each of the three cutting claws extending beyond the footprint of the tooth as defined by the outer perimeter of the attachment surface, the first edge having a first trailing surface facing opposite from the rotational direction, each of the three cutting claws including a portion of the leading working surface and a portion of the first trailing surface;
- and
- a second edge having at least three cutting claws, each of the three cutting claws, extending beyond the footprint of the tooth as defined by the outer perimeter of the attachment surface, the second edge having a second trailing surface facing opposite from the rotational direction, each of the three cutting claws including a portion of the leading working surface and a portion of the second trailing surface.
