Abstract
Abstract A cutting mill for disintegrating synthetic plastic wastes and the like having a rotor provided with cutting blades that operate against a pair of stationary knives. The rotor is disposed within a disintegrating chamber into which material to be disintegrated is fed through a feeding chute. The lower wall of the feeding chute intersects the lower portion of the rotor.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
137 words
A disintegration device for plastic wastes, particularly for wastes of endless dimensions, comprising: a rotor having a plurality of cutting knives; a disintegration chamber housing said rotor; a pair of stationary cutting knives situated opposite one another in said disintegration chamber, the knives of said rotor operating against the stationary knives in the direction of rotation of said rotor at an approximate angle of 30* before a vertical line extended through the axis of rotation of said rotor; and a feeding chute for wastes to be disintegrated that directs said wastes into said disintegration chamber, with the lower wall of said feeding chute intersecting the lower cutting point between the knives of the rotor and the lower stationary knife at an angle of about 90* to 120*, with reference to the cutting plane between the stationary knives.
Claim 2
Dependent Claim
137 words
A disintegration device for plastic wastes, particularly for wastes of endless dimensions, comprising: a rotor having a plurality of cutting knives; a disintegration chamber housing said rotor; a pair of stationary cutting knives situated opposite one another in said disintegration chamber, the knives of said rotor operating against the stationary knives in the direction of rotation of said rotor at an approximate angle of 30* before a vertical line extended through the axis of rotation of said rotor; and a feeding chute for wastes to be disintegrated that directs said wastes into said disintegration chamber, with the lower wall of said feeding chute intersecting the lower cutting point between the knives of the rotor and the lower stationary knife at an angle of about 90* to 120*, with reference to the cutting plane between the stationary knives.
Claim 3
Dependent Claim
46 words
A device as set forth in claim 1 characterized in that the feeding chute has relatively narrow and generally parallel upper and lower walls, with the upper wall having an upper and lateral extension forwardly of the rotor to form a part of the disintegration chamber.
