Abstract
A grinding machine having a mounting arrangement and an anvil. The grinding machine generally including a feed table and a grinding drum positioned within a mill box. The mounting arrangement being configured to support an end of the feed table and the anvil. The anvil including a wedge-shaped portion and having a length. The length of the anvil being configured to extend beyond sides of the mill box.
Claims17
A grinding machine, comprising:
- a) a mill box having opposite sides, the opposite sides of the mill box defining a grinding width, each of the sides defining an aperture;
- b) a grinding drum positioned within the mill box, the grinding drum having an axis of rotation;
- c) an anvil having a cross-section, the cross-section including a wedge-shaped portion and a rectangular portion, the wedge-shaped portion having a tapering surface extending from a first reference point to a second reference point, each of the first and second reference points being located a distance from the axis of rotation of the grinding drum, the second reference point of the tapering surface being located farther from the axis of rotation than the first reference point, the anvil being positioned within the apertures of each of the sides of the mill box, the anvil having a length greater than the grinding width of the mill box such that ends of the anvil extend beyond the sides of the mill box;
- d) wherein the tapering surface of the anvil is oriented such that the first and second reference points are horizontally aligned with one another.

A grinding machine, comprising:
- a) a mill box having opposite sides, the opposite sides of the mill box defining a grinding width, each of the sides defining an aperture;
- b) a grinding drum positioned within the mill box;
- c) an anvil having a solid construction that defines a cross-section, the cross-section including a wedge portion and a rectangular portion, the wedge portion being defined by a tapering surface, the anvil being located in relation to the grinding drum such that during operation the tapering surface of the wedge portion is oriented perpendicular to vertical impact forces generated by the grinding drum, the anvil being positioned within the apertures of each of the sides of the mill box, the anvil having a length greater than the grinding width of the mill box such that ends of the anvil extend beyond the sides of the mill box.
