Pickup manifold PP-Series
The pickup manifold introduces the trims into the
tube system. It has to be designed in a way that
all pickup bells have the same air speed to pick
up the trims securely.

The vacuum and blow out-air is produced by a
venturi (principle of an aircraft wing).

The quality of the fluff has a big influence on
the ability to refeed the material. PORCESS
CONTROL grinders ensure always an outstanding
quality of the ground material.
By using the scissors cut principle PROCESS
CONTROLs grinders produce an absolute uniform
fluff with a narrow particle size distribution
and a high bulk density

12
Air eliminator AEN
The AEN ensures that the trims fall into the
cutting chamber by gravity, without turbulences
and ball-building. The constant alimentation into
the grinder is an important point for getting a
fluff of perfect quality.
Mounting Instruction Each AEN has a decal
showing how to mount the end of the pipe work.

Scrap compacting zone of a refeed machine
The fluff is compacted from a bulk density of
approx. 80 100 g/dm³ to approx. 300 400
g/dm³. The high degree of compaction ensures
that pumping of the extruder is avoided.

asr in comparison to repelletising
First of all it seems that repelletising has
advantages because you get a material that is
easy to handle, but The additional melt
process degrades the material chemically
the melt flow index (MFI) changes. The quality
of the product is influenced negatively. In-line
recycling does not bring additional heat into
the material. In-line recycling is always much
more cost effective regarding the energy
consumption.
