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
168 bar
direction of the channel exit.
In addition the counter pressure of the
material depends on the following factors:

Setting the counter
• 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.
