Ettlinger deals with contaminted plastic scrap
Ettlinger Kunststoffmaschinen
will take the opportunity of the
Fakuma 2015 trade show in Ger-
many this October to premiere
its ERF500 melt fi lter which has
been specially designed for
‘continuous processing’ of plas-
tics scrap with up to 18% con-
tamination by weight.
The ERF500 is the largest in its family and
is capable of handling ‘any kind of feed-
stock’, with throughputs of up to 6 tons

per hour, Ettlinger says. The solution offers
‘reliable and pres sure-stable’ treatment
of the material, the company adds.
The central component of the ERF melt
fi lter is a rotating, cylindrical fi lter screen
with millions of conical holes that can
be supplied with a wide variety of rat-
ings. The rotary motion of the fi lter drum
simultaneously supports the blending
effect and ensures optimal homogene-
ity in the melt.
‘Whereas conventional piston screen

changers can require many screen
changes per day – each one causing the
fi ltration process to be interrupted – the
ERF achieves a trouble-free service life
of several weeks with no disruptions to
production,’ Ettlinger notes.

SPOTLIGHT

‘Every year, about 460 billion PET
bottles are currently produced world-
wide,’ Pallmann points out. ‘In Europe
alone, an unbelievable 65 billion or
more PET bottles were recycled in
2013.’ With this in mind, Pallmann has
created the Panther UltraGranulator,
which allows for individual PET bottles
to be continuously fed into the cutting
chamber via a conveyor belt. Massive,
angled rotor knives work with a very
close cutting gap against opposing
slanted counter knives and cut the
bottles into fl akes.
‘The special rotor really does cut
diagonally and this keeps energy con-
sumption to a minimum,’ Pallmann
states. ‘The lower part of the housing
is fitted with a large screen which
holds the PET fl akes in the cutting
chamber until they are discharged
through the screen holes.’
The mesh size can be selected by the
operator, and this determines the size

of the fl akes and the throughput rate
of the granulator; throughput rates of
up to 3.5 tonnes per hour are possible
with a fl ake size of approximately 14
mm. After being cut, the material is
pneumatically suctioned and trans-
ported to a cleaning system in which
the PET fl akes are separated from the

polyethylene contained in the bottle
caps. The resulting raw material can be
used to manufacture new plastic bot-
tles, as well as carpets and textiles.
The Panther UltraGranulator is said to
be ideal for ‘continuous operation
under tough conditions, seven days a
week’. If required, Pallmann can also

provide a sorting system to separate
the various secondary raw materials.

Pallmann Maschinenfabrik has
extended its range of robust
Panther granulators by adding
a model that is designed for
recycling reusable materials
from PET bottles.
