Setting
the
counter
pressure
Type
CC20V
is
delivered
with
a
manual
channel
adjustment.
Optionally
the
machine
can
be
delivered
with
a
hydraulic
channel
adjustment.
The
operation
pressure
depends
on
the
counter
pressure
of
the
material
in
the
channel.
In
order
to
achieve
this
counter
pressure
the
cross
‐
section
is
smaller
in
the
direction
of
the
channel
exit.
In
addition
the
counter
pressure
of
the
material
depends
on
the
following
factors:
•
Coefficient
of
friction
for
the
channel
walls,
which
drops
during
the
running
period
of
the
system,
•
Coefficient
of
friction
of
the
material
to
be
compressed,
which
can
fluctuate
strongly
(e.g.
relatively
high
for
cardboard
and
relatively
low
for
foils),
•
Fill
height
in
the
funnel
at
the
start
of
the
press
process.
The
funnel
must
be
at
least
filled
with
material
to
the
upper
edge
of
the
press
body.
•
Adjusting
the
clamping
elements
on
the
baling
channel,
which
must
be
adjusted,
especially
during
the
run
‐
in
period
and
when
material
is
changed.
