The shredder rotor is equipped with special knife holders
that retain the square cutter blocks. An efficient cutting
design ensures a clean cut and reduces heat build up.
Cutting knives may be turned up to four times to utilise the
four cutting edges prior to re sharpening. Depending on
material type and the final size required by the customer,
various types of cutters and screens are available.
Features of ZSS rotors:
n Unique
hardened alloys for demanding applications
n Adjustable
knife height to suit specific material and application
n Bolted knife
holders for simplified maintenance procedures and reduced
down time
ZERMA ZS series shredders are equipped with a hydraulic
feeding system. The heavy duty swinging ram is equipped with
over dimensioned bearings and supports.
The swinging ram is equipped with a serrated ram plate to
minimise slippage when shredding bulky items such as
bundles, lumps or pallets. To eliminate material build up
between the pusher and cutting chamber, the pusher is
equipped with scrapers.
The hydraulically operated ram forces material against the
rotor and in the event there is an overload situation, the
ram will stop and then move backwards to release pressure on
the rotor. The rotor then automatically reverts to the
forward pushing motion and in this way throughput is
optimised.
The special swing design eliminates the need for guide rails
inside the cutting chamber, reducing wear and the risk of
the pusher jamming. The swinging ram design also reduces the
footprint of the machine.
Standard shredders are equipped with two speed hydraulic
systems allowing the ram to move faster in a no load
situation.
