JAWS, TEETH AND CUTTING BLADES
Jaws
The jaws are operated by the hydraulic cylinder. One jaw is fixed and the other,
equipped with breaking teeth, is moving. Crushing is performed using the crushing
teeth of the jaws.
Crushing teeth
Crushing is performed using the crushing teeth of the jaws. The long-lasting,
convex teeth are made of special steel. They are fastened with screws and can be
replaced.
Crushing plate
The teeth of the crushing plate are made of special steel. The teeth are welded
directly onto the plate. The crushing plate is removable, so that the teeth can be
serviced separately.
Cutting blades
The cutting blades are fastened with screws. You can turn them to use unused
cutting edges or replace them with new cutting blades. See “Turning and changing
cutting blades” on page 49.
