Abstract An improved destructor mechanism is described for reducing documents, paper and similar fibrous materials to a fluffy illegible consistency. The mill to be described is equipped with a hood at the entrance to the mill, into which material which is not accepted initially by the mechanism is discharged back through the entrance and circulated, to be reintroduced through the entrance into the mechanism until it is accepted and reduced to the aforesaid fluffy consistency. The mill to be described is particularly advantageous, in that bulky material can be fed into it without the tendency for the apparatus to become jammed, and no special care need be taken in the manner in which the material is fed into the mechanism, or of the size or weight of the material.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
149 words
A milling mechanism for reducing fibrous material, such as documents, paper and the like, into a fluffy illegible consistency including: a housing defining at least one compartment for the milling mechanism; a rotor including a plurality of hammer elements mounted in said compartment for rotation about a horizontal axis; said housing including components defining a wall for said compartment, said components defining an opening in the wall at the top of said compartment for receiving material into said compartment; and a further component mounted on said housing and extending as a hood around said opening, said hood defining a side entrance for receiving said fibrous material into said milling mechanism and having a generally arcuate configuration so that material discharged from said compartment through said opening is circulated unimpeded around the inner surface of the arcuate wall of a chamber formed by said hood and back into said opening.

A milling mechanism for reducing fibrous material, such as documents, paper and the like, into a fluffy illegible consistency including: a housing defining at least one compartment for the milling mechanism; a rotor including a plurality of hammer elements mounted in said compartment for rotation about a horizontal axis; said housing including components defining a wall for said compartment, said components defining an opening in the wall at the top of said compartment for receiving material into said compartment; and a further component mounted on said housing and extending as a hood around said opening, said hood defining a side entrance for receiving said fibrous material into said milling mechanism and having a generally arcuate configuration so that material discharged from said compartment through said opening is circulated unimpeded around the inner surface of the arcuate wall of a chamber formed by said hood and back into said opening.
Claim 3
Dependent Claim
43 words
The combination defined in claim 1, and which includes a chute disposed in a generally horizontal plane and mounted adjacent said side entrance for feeding said fibrous material into the interior of said milling mechanism through said entrance and down through said opening.
