POWERFUL AND VERSATILE
AK/NZ SERIES IN OPERATION
The AK / NZ grinders process green waste, garden
and park waste, biowaste, pre-shredded log and
roots, waste wood and wooden pallets.
For special applications, the AK / NZ grinders
can ideally be combined with other DOPPSTADT
products, such as shredders or screens.
We will be pleased to give you advice.
ONE GRINDER – MANY POSSIBLE APPLICATIONS
Grinding green waste
Grinding of waste wood
AK/NZ SERIES
The grinders of the AK and NZ series reduce
the material by means of the large flail drum.
The free-swinging flails inside, provided with
replaceable wearing tips, grind the material
tearing it along the baffle plate. According to
the demands on the throughput capacity and
the material size, various mesh sizes of the
grinding basket are available.
The Doppstadt grinders stand out for their free-
swinging flail holders with separately replaceable
wearing tools and the heavy gyrating mass of
the flail drum working at approx. 1,000 rpm.
• Easy maintenance thanks to large protection
doors on all sides and the central lubrication
• Separate drives for scraper floor and feed-in
roller optimizing the material feed and the
throughput (AK 435)
• Wide range of possible applications as all the
shredding tools of the mobile Doppstadt series
can be used.

FEED-IN ROLLER
The feed-in roller with reversing
function pulls the material evenly
to the grinding chamber.
DRIVE
Mechanic drive by rotary current motor
and V-belts.
REMOTE CONTROL
All the functions of the
machine can be controlled
with the remote control,
e.g. by the wheel loader
operator.
Fe-SEPARATION By means of an overband
magnet* the contaminants
containing iron can be separated
after each process step.
LOWER DISChARGE CONVEYOR
Discharge of the grinded material and of
the spillage beneath the scraper floor.
MAINTENANCELarge doors for optimum maintenance.
GRINDING BASKET
You will determine the desired grain size of
the material by choosing among grinding
baskets with mesh sizes between 30 mm
and 400 mm (1.2"–15.7"). With the quick-
changing system it takes only 15 minutes
to change the baskets.
FLAIL DRUM
The large flail drum with approx. 2,5 t
(5,512 lb) gyrating mass (AK 435E/
NZ 180) grinds the materials. The
free-swinging flail holders with easily
replaceable tips are resistant against
contaminants. The tips can be chosen
according to the material.
BAFFLE PLATE
A baffle plate with teeth
supports the grinding process.
SCRAPER FLOOR
The patented, load-sensing
scraper floor transports the
material to the feed-in roller.

KEY BENEFITS• Continuous grinding by means of load
sensing material in-feed
• Resistance against foreign objects due to free swinging flails and compensating counter baffle and sieve
• Individually replaceable grinding tips (flail/teeth)
• Rapid exchange system for the meshed grinder sieve
• Minimisation of dust and vibration in the drive compartment due to separation of the drive and grinding units
• Combination options with other Doppstadt plant
• One-man operation (remote control of main functions)

AK 235 E
The solution of various grinding tasks is easy for the
DOPPSTADT AK 235 E grinder with its flail drum. It accom-
plishes its tasks by the free-swinging flail principle combined
with the grinding basket. Thanks to various, quickly replace-
able tools, the AK 235 E can easily be adjusted to the different
grinding tasks. The efficient mechanic power transmission is
carried out by V-belt drive of the flail drum and hydraulic drive
of the additional components. Furthermore, highest flexibility
for a quick and universal application is guaranteed.
