Abstract
A machine having a snag anvil that prevents an excessive intake rate of material into a grinding or chipping chamber of the machine. The snag anvil includes a recessed impact plane located between longitudinal edges that snag material entering the grinding chamber at an excess intake rate. The machine also includes an open feed roller constructed to prevent material plugging, and a sealing arrangement that eliminates the build up of chip piles underneath the machine.
Claims21
An anvil for use in a grinding machine, the anvil comprising:
- a) a base defining a depression formed between first and second longitudinal edges, the depression defining an impact plane, the first and second longitudinal edges located a distance above the impact plane;
- and
- b) mounting structure formed in the base, the mounting structure being arranged so that the anvil can be reversibly mounted to the grinding machine in either of both of a first orientation and a second orientation.
An anvil for use in a grinding machine, the anvil comprising:
- a) a base portion having a generally rectangular shape, the base portion defining an impact plane that extends from a first end to a second end of the base portion;
- and
- b) a first triangular portion formed integral with the base, the first triangular portion including a ramped surface extending outward from the impact plane of the base portion, the ramped surface defining a first longitudinal edge located a distance above the impact plane.
A grinding machine, comprising:
- a) a grinding chamber including a grinding drum;
- b) a conveying system that transports material to the grinding chamber, the conveying system defining a conveying plane;
- and
- c) an anvil located between the grinding chamber and the conveying system, wherein material fed into the grinding chamber by the conveying system passes over the anvil, the anvil including:
- i) a base portion having a first end, a second end, and side surfaces extending between the first and second ends, the base portion defining a recessed impact plane;
- ii) a ramped surface extending upward from the recessed impact plane of the base portion;
- and
- iii) a longitudinal edge defined by the conjunction of the ramped surface and one of the side surfaces, the longitudinal edge being located a distance above the recessed impact plane.
A method of assembling an anvil to a grinding machine, the grinding machine including a grinding chamber, the method comprising:
- a) providing a reversible anvil having ramped surfaces extending toward first and second opposing longitudinal edges, the ramped surfaces defining a recessed impact plane therebetween;
- b) selectively orienting the anvil in one of a first orientation and a second orientation, the first longitudinal edge of the anvil being positioned toward the grinding chamber in the first orientation, the second longitudinal edge of the anvil being positioned toward the grinding chamber in the second orientation;
- and
- c) mounting the reversible anvil adjacent to the grinding chamber in the selected orientation.

(canceled)
A chipper machine, comprising:
- a) a chipping chamber including a chipping drum;
- b) an incoming material region where material is input into the chamber;
- and
- c) an anvil located between the chipping chamber and the incoming material region, wherein material fed into the chipping chamber passes over the anvil, the anvil including:
- i) a base portion having a first end, a second end, and side surfaces extending between the first and second ends, the base portion defining a recessed impact plane;
- ii) a ramped surface extending upward from the recessed impact plane of the base portion;
- and
- iii) a longitudinal edge defined by the conjunction of the ramped surface and one of the side surfaces, the longitudinal edge being located a distance above the recessed impact plane.
