Abstract
Abstract Am apparatus for comminuting grain in which a feed rotor entrains the grain along its underside and propels the grain at high velocity against blades rotated in the opposite direction on a comminuter rotor which cooperates with fixed teeth attached to the housing walls.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
97 words
A grain comminuter comprising a housing formed with a grain inlet; an impeller rotatably mounted in said housing for projecting grain in one direction along a path; an impact rotor mounted rotatably in said housing and formed with a peripheral array of outwardly projecting blades displaceable on said rotor to intercept said path and rotatable in a direction opposite the direction in which said grain is projected by said impeller; and at least one array of repeller blades attached to said housing for intercepting grain entrained by said impact motor and cooperating therewith to comminute the grain.
Claim 2
Dependent Claim
97 words
A grain comminuter comprising a housing formed with a grain inlet; an impeller rotatably mounted in said housing for projecting grain in one direction along a path; an impact rotor mounted rotatably in said housing and formed with a peripheral array of outwardly projecting blades displaceable on said rotor to intercept said path and rotatable in a direction opposite the direction in which said grain is projected by said impeller; and at least one array of repeller blades attached to said housing for intercepting grain entrained by said impact motor and cooperating therewith to comminute the grain.
Claim 3
Dependent Claim
126 words
The grain comminuter defined in claim 1 wherein said impeller is a rotor provided with fan blades and is rotated in one sense for sweeping said grain along one side of the impeller rotor, said comminuter further comprising a regulator extending from said opening along said side of said impeller for controlling the rate of flow of the grain therethrough, said impact rotor being formed along its periphery with angularly spaced slots, each receiving an array of toothed impact blades separated by spacer lamellae establishing the distance between the toothed blades, said impact rotor being positioned to bring the side thereof opposite the side of the impeller rotor into engagement with the grain, said repeller blades being rotatably adjustable to replace the effective cutting edges thereof.
