Abstract
There is provided an apparatus and method for comminuting a material. The apparatus may comprise a chamber and an inner surface with a plurality of protrusions, and a hammer positioned within said chamber comprising an outer surface having a plurality of second protrusions configured to engage with the first protrusions. The outer and inner surfaces may be separated by a gap distance which defines a comminution zone. The anvil may be rotated to cause a material to be comminuted as the material passes through the comminution zone.
Claims25
An apparatus for comminuting a material, the apparatus comprising:
- an anvil comprising a chamber and an inner surface, said inner surface having one or more anvil panels, each of said one or more anvil panels containing a plurality of anvil protrusions, said anvil configured to rotate about an anvil axis;
- and
- a hammer positioned within said chamber, said hammer including an outer surface, said outer surface having one or more hammer panels, each of said one or more anvil panels containing a plurality of hammer protrusions configured to engage with said plurality of anvil protrusions, said outer surface and said inner surface separated by a gap distance to define a comminution zone, and said hammer configured to rotate about a hammer axis parallel to said anvil axis and radially offset from said anvil axis;
- wherein said apparatus is configured to receive said material in said chamber, and wherein said anvil and said hammer are configured to comminute said material as said material travels through said comminution zone.
A method of comminuting a material, the method comprising:
- transporting said material to a chamber of an anvil, said chamber including an inner surface, said inner surface having one or more anvil panels, each of said one or more anvil panels containing a plurality of anvil protrusions;
- rotating said anvil about an anvil axis;
- rotating a hammer positioned within said chamber about a hammer axis parallel to said anvil axis and axially spaced apart from said anvil axis, said hammer comprising an outer surface, said outer surface having one or more hammer panels, each of said one or more hammer panels containing a plurality of hammer protrusions configured to engage with said plurality of anvil protrusions, wherein said outer surface and said inner surface are separated by a gap distance to define a comminution zone;
- comminuting said material as said material travels through said comminution zone.
