Abstract
A blade for a comminution machine includes a first attack face facing in a first direction to perform comminution when the blade is rotated about an axis of rotation in a first direction. The blade also includes a second attack face facing in a second direction to perform comminution when the blade is rotated about the axis of rotation in a second direction substantially opposite to the first direction. A radial exterior of the first attack face and a radial exterior of the second attack face are connected along an arc subtending at least 30 degrees and less than 110 degrees with respect to the axis of rotation.
Claims22
A blade for a comminution machine comprising:
- a first attack face facing in a first direction to perform comminution when the blade is rotated about an axis of rotation in a first rotational direction;
- a second attack face facing in a second direction to perform comminution when the blade is rotated about the axis of rotation in a second rotational direction substantially opposite to the first rotational direction, and the second attack face including a second attack face bursting point offset from a radial exterior of the second attack face toward the axis of rotation;
- and
- wherein a radial exterior of the first attack face and the radial exterior of the second attack face are connected along an arc subtending at least 30 degrees and less than 110 degrees with respect to the axis of rotation.
A blade for a comminution machine comprising:
- a first attack face facing in a first direction to perform comminution when the blade is rotated about an axis of rotation in a first rotational direction and extending from a radial outermost point of the blade;
- a second attack face facing in a second direction to perform comminution when the blade is rotated about the axis of rotation in a second rotational direction substantially opposite to the first rotational direction and extending from the radial outermost point of the blade;
- wherein the first attack face recedes away from the radial outermost point of the blade toward the axis of rotation and toward a first direction transverse to the axis of rotation to create a displacement angle of at least 10 degrees;
- and
- wherein the second attack face advances from the radial outermost point of the blade toward the axis of rotation and toward the first direction transverse to the axis of rotation to create a displacement angle of less than 10 degrees.
A blade for a comminution machine comprising:
- a first attack face facing in a first direction to perform comminution when the blade is rotated about an axis of rotation in a first rotational direction and extending from a radial outermost point of the blade;
- a second attack face facing in a second direction to perform comminution when the blade is rotated about the axis of rotation in a second rotational direction substantially opposite to the first rotational direction and extending from the radial outermost point of the blade;
- a second attack face bursting point extending from the second attack face and offset from a radial exterior of the second attack face toward the axis of rotation;
- and
- wherein the first attack face includes a hook.
