Pre-shredder makes all the
difference for FBSerwis
Polish company FBSerwis needed a reliable shredder to crush municipal solid

waste and process mixed plastics. Vecoplan replaced one of the recycler’s old

machines with an energy efficient VVZ 2500 pre-shredder with great results.

teleconference technology.

POWERFUL YET EFFICIENT
Trucks deliver mixed municipal waste
to the plant. Front-end loaders pick
up the input material and take it to a
conveyor system which feeds the new
pre-shredder. The machine, which is
equipped with replaceable knives and
counter knives to achieve consistent
granularity, shreds the material to a
uniform particle size of less than 250
mm. The robust VVZ is equipped with
an energy efficient HiTorc drive.
This dynamic, quick starting, high-
torque synchronous drive has 247 kW
of power and is regulated by a 315
kW frequency converter. It requires no
mechanical elements such as belt
drives, flywheels or couplings. The
HiTorc drive is also much less sensitive
to impurities.

Thanks to this new equipment, which
can process around 42 tonnes per
hour, FBSerwis, located in Poland’s
capital Warsaw, is now able to shred
almost 200 000 tonnes of recyclables
a year. The pre-shredder yields high-
quality output with particle sizes
below 250 mm.
‘We collect municipal solid waste and
use it to make high-quality refuse-
derived fuel (RDF),’ says Arkadiusz

Mężyk, ceo of FBSerwis Kamieńsk, an
subsidiary of Budimex. As well as dis-
posal, processing and collection of
waste, FBSerwis Group provides tech-
nical services for buildings and indus-
trial facilities, road maintenance and
street lighting infrastructure.
Because FBSerwis Kamieńsk has a
processing line for municipal waste
with particle sizes greater than 80 mm
and mixed plastics, it needed a reli-

able pre-shredder to increase perfor-
mance. This led it to Vecoplan.

UPDATING EXISTING LINE
Vecoplan installed its VVZ 2500 T pre-
shredder to meet the company’s
needs. ‘This double-shaft shredder
can even process difficult and contam-
inated materials such as domestic and
commercial waste,’ says its Polish mar-
ket expert Ireneusz Suszyna. ‘We
delivered the system, coordinated the
whole project, planned the layout in
detail, set up the mechanical and elec-
trical connections and finally commis-
sioned the system.’ The biggest chal-
lenge? ‘We had to integrate the pre-
shredder into the existing line and
remove the old machine. At the same
time, we had to avoid downtimes.’
The installation had to take place
quickly.
Engineers matched the system to the
customer’s input and output require-
ments by installing suitable rotors and
blades and by selecting the right
screen. They fine-tuned these compo-
nents according to the FBSerwis’
needs during numerous tests at
Vecoplan’s in-house technical centre.

ELIMINATING ERRORS
Two strong steel doors provide access
to the machine for service and mainte-
nance. But what happens if the system
suddenly shuts down? In such cases,
the customer can turn to a service
hotline available around the clock,
every day of the year. Help comes
over the phone right away and techni-
cians first try to rectify the problem via
remote diagnostics.
