Device for comminuting empty containers

Device for comminuting empty containers selected from the group consisting of beverage bottles and beverage cans made of plastic/PET or tin plate, comprising

• a housing/frame (1), having a fill-in opening (2), as well as an exit opening (3), and
• a cutting unit (4) disposed in the housing (1), as well as means for drive and control of the cutting unit (4),
• whereby
• the cutting unit (4) contains at least cutting rollers (4.1 and 4.2), disposed at a distance from one another with regard to their axes of rotation, wherein
• the cutting unit (4) is a cutting unit (4) used for shredding paper or paperboard in document shredders,
• in which
• each cutting roller (4.1 and 4.2) has multiple cutting disks (5), which are each disposed at an axial distance from one another by means of a circumferential groove (gap E), and
• the axes of rotation (A1 and A2) of the cutting rollers (4.1 and 4.2) are disposed at an axial distance from one another, in such a manner that adjacent cutting disks (5) of the two cutting rollers (4.1 and 4.2) mesh,
• whereby a gap, the cutting play (16), is present between two side flanks (5.2) of adjacent cutting disks (5), which flanks face one another, in each instance;
• wherein the cutting mechanism is a particle cut cutting mechanism and wherein the cutting disks (5) have grooves (6) worked into their circumference surface (5.1), whose trailing flank (6.3), in the direction of rotation (R, R′), forms a cutting tooth (5.3), together with the circumference surface (5.1), which tooth has an acute angle and points in the direction of rotation, whereby the groove flank (6.3), which begins at the tip, has a linear progression as well as a progression directed counter to the direction of rotation (R, R′), and the subsequent transition region (6.4) to the groove base (6.2) and/or the groove flank (6.1) that lies in the direction of rotation is configured in arc shape.
