CONSISTENT
IN-LINE SCRAP
REPROCESSING
The ScrapSaver volumetrically feeds ground light density film scrap
to the extruder feed screw in a stable, consistent flow. Conair trim
systems handle all kinds of film and sheet waste and return it
directly to the extruder at rates of 25% or more.
Direct in-line reprocessing of scrap material eliminates scrap
handling costs and the risk of cross-contamination. Scrap
inventory and labor expenses are significantly reduced and
additional heat histories associated with secondary re-pelletizing
or densifying operations are eliminated.

DIRECT CLOSED-LOOP RECLAIM INCREASES PROFITS
The ScrapSaver delivers a consistent
ratio of ground scrap and virgin pellets.
Two hoppers maintain component segregation until discharge approximately
1/2 - 1 inch {12-25 mm} above the
screw flights. An agitator auger in the
fluff hopper ensures reliable feeding of
the scrap, while the virgin pellets are
gravity fed. To optimize scrap re-feed
rates and protect process stability,
pellets enter the flights in an annular
ring surrounding the fluff. This creates
a consistent flight-to-flight mix ratio
and provides a steady, and consistent
flow of material.
Four different auger sizes are available
to match extruder sizes up to eight (8)
inch {200 mm}. Scrap re-feed rates are
typically up to 25% of overall extruder
throughput, but higher rates may be
possible depending on the extruder
feed section, screw design and the
end-product being extruded.

■

Long life motor and gearboxes
The vertical scrap auger is driven with a reliable AC inverter motor. The drive
system comes equipped with multi-level current overload protection with alarm
status to protect against premature drive and gearbox failure.

■

Won’t overfeed or underfeed the process
The ScrapSaver follows any change in the extruder throughput rate. The following
circuit provides consistent feed, avoids “cramming” the flights and eliminates
related extruder surging. A low speed cut-out and an internal level sensor with
delay timer controls the scrap granulator roll feed to prevent overfeeding.

■

Agitation prevents bridging
Agitator arms on the auger are designed to prevent bridging in the ScrapSaver
machine and keep a consistent flow of ground scrap into the extruder.

■

Inexpensive operation
Automated system virtually eliminates operator involvement and scrap handling
costs.

■

Additive feeder side mount
A replaceable sight glass accommodates TrueFeed and other additive feeders
for direct input to the ScrapSaver pellet feed chute.
