Abstract
Abstract A comminuting plant is equipped with a comminuting machine for the coarse comminution of bulky material, and a granulating machine for the fine granulation of the precomminuting material from the comminuting machine. The comminuting machine includes at least two parallel shafts having several rotary bodies arranged on each shaft to provide cutting disks. Between the cutting disks in each case, there are arranged separate spacers. The spacers are smaller in diameter than the cutting disks, and turn with the shafts in such a way that the cutting disks of adjacent shafts cooperate, as the cutting disks touch each other in rotation, at least intermittently in the zone of their facing cutting edges. The circumferential surfaces of the spacers provide interspaces for the passage of the comminution material. The granulating machine includes at least two shafts disposed in one plane and at least two further shafts arranged in another plane, preferably parallel to the first plane, several rotary bodies being arranged on each shaft to provide granulating disks, each disk having a toothing. Between the granulating disks in each case, there are arranged separate spacers. The disk spacers are smaller in diameter than the disks, and are turnable with their respective shafts in such a way that the granulating disks of one shaft are engaged between the granulating disks of at least one shaft lying in the same plane and of at least one of the shaft lying in the other plane at least to a depth greater than the depth of the toothing in the disks.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
234 words
A comminuting machine for comminuting material comprising: (a) a first parallel rotary shaft and a second parallel rotary shaft; (b) means for rotating said parallel rotary shafts in opposite directions; (c) a plurality of cutting disks disposed on said first and second parallel shafts, said cutting disks each being provided on both peripheral edges thereof with a plurality of spaced apart, arcuate cutting edges, said arcuate cutting edges having a circumferential length corresponding to a central angle of between 20° and 80°; and (d) a plurality of cutting disk spacers removably disposed alternately with said cutting disks on said parallel shafts so that said spacers rotate with said shafts, said cutting disk spacers having a diameter smaller than a diameter of the cutting disks, said cutting disks on said parallel shafts being allocated to each other in pairs only, and upon rotation, touch each other on a corresponding, peripheral, arcuate cutting edge surface when in register and adjacent to each other, said cutting disk spacers having portions defining a space therebetween for the passage of comminuted material, said cutting disk spacers being provided on an end face portion with a cross-sectional configuration which is relatively the same as a cross-sectional configuration of an abutting associated cutting disk, said cutting disk spacers being conical in their axial length, and complimentary conical cutting disk spacers on said parallel shafts each tapering in an opposite axial direction.
Claim 2
Dependent Claim
234 words
A comminuting machine for comminuting material comprising: (a) a first parallel rotary shaft and a second parallel rotary shaft; (b) means for rotating said parallel rotary shafts in opposite directions; (c) a plurality of cutting disks disposed on said first and second parallel shafts, said cutting disks each being provided on both peripheral edges thereof with a plurality of spaced apart, arcuate cutting edges, said arcuate cutting edges having a circumferential length corresponding to a central angle of between 20° and 80°; and (d) a plurality of cutting disk spacers removably disposed alternately with said cutting disks on said parallel shafts so that said spacers rotate with said shafts, said cutting disk spacers having a diameter smaller than a diameter of the cutting disks, said cutting disks on said parallel shafts being allocated to each other in pairs only, and upon rotation, touch each other on a corresponding, peripheral, arcuate cutting edge surface when in register and adjacent to each other, said cutting disk spacers having portions defining a space therebetween for the passage of comminuted material, said cutting disk spacers being provided on an end face portion with a cross-sectional configuration which is relatively the same as a cross-sectional configuration of an abutting associated cutting disk, said cutting disk spacers being conical in their axial length, and complimentary conical cutting disk spacers on said parallel shafts each tapering in an opposite axial direction.
Claim 3
Dependent Claim
23 words
A comminuting plant according to claim 1, wherein on at least one cutting disk there are provided arcuate cutting edges with differing lengths.
Claim 4
Dependent Claim
36 words
A comminuting plant according to claim 2, wherein the cutting disk spacer end face abutting the associated cutting disk is polygonal in cross-section, according to the number of arcuate cutting edges of said abutting cutting disk.
Claim 5
Dependent Claim
14 words
A comminuting plant according to claim 3, wherein said parallel shafts are driven asynchronously.
Claim 6
Dependent Claim
59 words
A comminuting plant according to claim 4, wherein each of the two parallel shafts has an axis, the axes of the two parallel shafts defining a plane, said plane inclined by an angle of preferably not more than 30° to a plane which is relatively perpendicular to a direction of flow of the material being fed into the comminutor.
Claim 7
Dependent Claim
174 words
A comminuting plant comprising: (a) a granulating machine having at least two parallel first shafts arranged in a first plane; and (b) at least two parallel second shafts arranged in a second plane, said first and second planes being disposed parallel to each other, and axes of said first and second shafts defining corners of a square; (c) a plurality of granulating disks disposed on said first and second shafts, said disks having a plurality of teeth portions disposed on a peripheral edge thereof, said teeth portions having a selected toothing depth; and (d) spacer disks alternately disposed on said parallel shafts between said granulating disks whereby a granulating disk on one shaft in one of the said planes engages between a pair of granulating disks on at least another shaft lying in said first plane and between a pair of granulating disks on at least another shaft lying in said second plane at least to a depth that is greater than the toothing depth of said teeth portions of the engaging granulating disk.
Claim 8
Dependent Claim
174 words
A comminuting plant comprising: (a) a granulating machine having at least two parallel first shafts arranged in a first plane; and (b) at least two parallel second shafts arranged in a second plane, said first and second planes being disposed parallel to each other, and axes of said first and second shafts defining corners of a square; (c) a plurality of granulating disks disposed on said first and second shafts, said disks having a plurality of teeth portions disposed on a peripheral edge thereof, said teeth portions having a selected toothing depth; and (d) spacer disks alternately disposed on said parallel shafts between said granulating disks whereby a granulating disk on one shaft in one of the said planes engages between a pair of granulating disks on at least another shaft lying in said first plane and between a pair of granulating disks on at least another shaft lying in said second plane at least to a depth that is greater than the toothing depth of said teeth portions of the engaging granulating disk.
