Abstract
Abstract A granulating machine of substantially modular construction. The hopper-input module includes baffles to prevent flyback of the material being granulated. This module is mounted pivotally at two opposite ends to a cutting module permitting it to pivot downward or upward away from the cutting module for easy access to the cutting rotor for maintenance or cleaning, for example. The cutting module includes a rotor of essentially tubular construction on which rotor-knives are mounted. The rotor itself is mounted on a base or frame to which multi-edged, stationary bed-knives are mounted without using bolts or screws. The multiedged knives are capable of reorientation as the cutting edges become successively dulled. There is also a screen-mount module pivotally secured to the cutting module which includes a bendfree screen held in a cradle and clamped at two opposite ends by pressure elements bearing on it. The pivoting screen cradle permits access to the screen from above and to the under side of the rotor from below. Other features are described below.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
80 words
Apparatus comprising: a. an input section to which materials to be processed are applied, b. a rotor module adjacent said input section, said input section being pivotally connected at both ends to said rotor module, said rotor module including a supporting base, bearings for a rotor mounted to said base, and a rotor supported by said bearings, and c. a frame to which said rotor module is releasably secured, said rotor module also being releasably connected to said input section.
Claim 2
Dependent Claim
80 words
Apparatus comprising: a. an input section to which materials to be processed are applied, b. a rotor module adjacent said input section, said input section being pivotally connected at both ends to said rotor module, said rotor module including a supporting base, bearings for a rotor mounted to said base, and a rotor supported by said bearings, and c. a frame to which said rotor module is releasably secured, said rotor module also being releasably connected to said input section.
Claim 3
Dependent Claim
34 words
The apparatus according to claim 1 wherein said rotor comprises a unitary tube having a substantially hollow inner portion to whose outer surface a plurality of cutter knives are mounted at spaced intervals thereon.
Claim 4
Dependent Claim
29 words
The apparatus according to claim 2 wherein said cutter knives are double-edges and bolted to heavy elongated knive seats that are welded to the outside surface of said tube.
Claim 5
Dependent Claim
33 words
The apparatus according to claim 3 wherein said knives have a trapezoidal cross-section and longitudinal grooves in their bases and wherein said knife seats have corresponding mating ridges formed in their outer surfaces.
Claim 6
Dependent Claim
59 words
Comminuting apparatus or the like comprising: a. a hopper-input module, b. a cutter module, said hopper-input module being pivotally connected to said cutter module at two opposite points, and c. a screen-mount module pivotally connected to said cutter module at least one point, said screen being fixedly mounted to prevent axial movement by clamping means at both ends thereof.
Claim 7
Dependent Claim
59 words
Comminuting apparatus or the like comprising: a. a hopper-input module, b. a cutter module, said hopper-input module being pivotally connected to said cutter module at two opposite points, and c. a screen-mount module pivotally connected to said cutter module at least one point, said screen being fixedly mounted to prevent axial movement by clamping means at both ends thereof.
Claim 8
Dependent Claim
41 words
The apparatus according to claim 5 wherein said screen-mount module is disposed generally below said cutter module and includes a cradle carrying said screen which pivots downwardly from said cutter module thereby affording access to the underside of said cutter module.
Claim 9
Dependent Claim
37 words
The apparatus according to claim 5 wherein said cutter module includes a rotor comprising a unitary tube whose central portion is generally hollow and a plurality of cutter knives connected to the outer surface of said tube.
Claim 10
Dependent Claim
20 words

Claim 11
Dependent Claim
16 words
The apparatus according to claim 8 wherein said stationary knife is mounted solely by clamping means.
Claim 12
Dependent Claim
20 words
The apparatus according to claim 5 wherein said hopper-input module is pivotally mounted to said cutter module at two points.
Claim 13
Dependent Claim
40 words
The apparatus according to claim 5 with the addition of a container disposed to receive material processed by said cutter module, said container being constructed to roll into said apparatus to a position adjacent said cutter module or away therefrom.
Claim 14
Dependent Claim
16 words
The apparatus according to claim 8 wherein said stationary knife has a plurality of cutting edges.
Claim 15
Dependent Claim
18 words
The apparatus according to claim 12 wherein the transverse cross-section of said knife is shaped like a parallelogram.
Claim 16
Dependent Claim
25 words
The apparatus according to claim 13 wherein said knive has at least one groove running longitudinally thereof adapted to be engaged by a clamp member.
Claim 17
Dependent Claim
34 words
