Mill box for a horizontal grinder

A material reducing machine comprising:

• a rotary reducing drum being rotatable about an axis of rotation, the rotary reducing drum defining a reducing boundary that extends at least partially around the axis of rotation;
• an infeed conveyor for transporting material to a front portion of the rotary reducing drum, the infeed conveyor defining a conveyor plane;
• an anvil being positioned between the rotary reducing drum and the infeed conveyor, the anvil having a leading tip positioned immediately adjacent the reducing boundary, at least a portion of the anvil extending above the conveyor plane, the anvil being positioned at a first angle with respect to the conveyor plane, the first angle being greater than or equal to 6 degrees and less than or equal to 10 degrees,
• wherein the anvil is also positioned at a second angle with respect to the reducing boundary of the rotary reducing drum, wherein a first reference plane extends from the axis of rotation of the rotary reducing drum to the leading tip of the anvil and a second reference plane extends downward perpendicular to the first reference plane, wherein the second reference plane forms the second angle with the conveyor plane, the second angle being between 122 degrees and 130 degrees.
