Recycling of Film Waste
 Film recycling requires the know-how of
specialists. PALLMANN offers specific know-how for continuous, trouble
free recycling of trim waste as well as for film rolls, film packets, loose
and tangled film sheets.
In order to maximize profit,
both the choice of equipment and the total preparation
concept are important. A number of technical
details have to be observed such as the design of the
pneumatic conveying system, the separation of material
and conveying air in special cyclones, the choice of the
most appropriate feed roller system, and the choice of
appropriate film silos for guaranteed trouble free
storage and discharge of the film chips.
The size reduction of film
is a tough application for knife mills. The
typical 24 hour operation and the high cutting forces
required for film cutting call for optimized design of
the knife mill with regard to high precision in
manufacturing, mechanical stability, performance and
ease of servicing.
 Granulation
of Film Waste
PALLMANN offers
specific know-how for continuous, trouble-free,
recycling of trim waste, film rolls, film
packets, loose and tangled films and sheets.
The
Ultra-Granulator™,
Type
PS-F
and the
Granulator,
type PST are used in-line or at central locations to
cut film waste of all kinds. They are equipped
with an in-feed roller system for feeding film
scrap from the production line during start up.
On the PS-F loose film scrap can be fed by hand or with a
conveyor belt.
For the reduction of
tangled film piles, film packages and stacked
material, PALLMANN offers the Horizontal
Knife Mill, Type PSRH.
The feed material is automatically fed into the
rotor by means of a hydraulic intermittently
moved live bottom. The chips produced are best
suited as starting material for downstream
processing steps such as the
Plast-Agglomerator.

  Pulverizing
of Film Waste
The ORIGINAL
PALLMANN
Precision Knife Mill, type PS allows
the processing of film in form of rolls, edgings
as well as other loose material. The pulverized
powder is used for floor coverings and for the
production of pressed sheets.

Agglomeration of Film
Waste
When densification
is required, PALLMANN offers the
Plast-Agglomerator
System, type PFV.
 The Plast-Agglomerator
is a compact, fully automatic, and a proven
continuous system that converts thermoplastic waste
into high quality, free flowing granules, which are
later used as valuable raw material in further
processes.
All thermoplastic
materials such as PE, PP, PS, PA, PET, PVC, ABS,
XPS, PLA and composite materials of any kind, in the
form of bulky film, fiber, or foam waste, can be
continuously recycled with the same system.
This PALLMANN
Agglomeration process offers the unique advantage of
material gentle agglomeration with minimum heat and
minimum thermo-degradable damage; the material is
heated up with friction heat only and
is agglomerated, within a fraction of a second,
right below the melting point. Furthermore,
underwater cooling is not necessary.
