Revised compact version of the
ZSK Mc18 twin screw extruder
The new compact version of the twin screw
extruder is equipped with quick-release
clamps for the simple, quick replacement
of the feed hopper as well as the userfriendly CSpro control system. Coperion
will be showcasing the ZSK Mc18 compact
extruder with a screw diameter of 58 mm at
its booth at K 2016 (booth B19 in Hall 14).
The extruder will be fitted with the tried and
tested ZSK die head and a high-precision
S60 gravimetric feeder from Coperion
K-Tron above the feed barrel. In addition
to a ZS-B side feeder with patented feed
enhancement technology (FET) and a KT-20
feeder from Coperion K-Tron on a practical
swivel arm, the design of a new ZS-EG side
devolatilization will be on display.
At this year’s K 2016 trade fair (October 19 - 26,
2016, Düsseldorf, Germany), Coperion GmbH,
Stuttgart will be presenting a revised compact
version of its successful ZSK Mc18 series. Six
years after the initial launch of the series, which
is characterized by its specific torque of 18 Nm/
cm³, it has undergone a range of improvements
designed to further simplify handling.
New ZS-EG side devolatilization unit for
improved handling
Coperion has completely overhauled its ZSEG side devolatilization. It now offers clearly
improved features for fast and neat assembly
and disassembly. The new design of the ZSK’s
connection barrel has been optimized for quick
changing and allows all four mounting bolts to be
simultaneously undone in a circular movement.
What’s more, the screw shafts can be completely
loosened, cleaned, or changed in only a few moves.
Cleaning and maintenance times are sharply
reduced as a result.
The compact series offers many advantages. First,
it can be swiftly put into operation – meaning a
quick start to production and no costly start-up
times – as the control cabinet is fully prewired
upon delivery. In addition to a lower construction
height and a more clearly arranged control cabinet
design, one way that the compact version stands
out is through the improved accessibility of its
process section. The cable ducts are arranged
under the process section, and the control cabinets
are located at motor and gearbox-height. The
separately mounted drive cabinet results in a
reduction in installation space as well as in the
weight of the machine. The machine and the
control system can be quickly and easily connected
using a small number of clearly identified cable
connections. All of these benefits result in a quicker
return on investment than with conventional
machines.

The new ZS-EG is fitted with radial shaft sealing
rings. As a result, the lantern area remains visible.
They additionally permit nitrogen purging in an
explosive environment. Thanks to the new seals,
there is no longer a vacuum in the gear lanterns,
and the service life of the gear-side shaft seal is
considerably greater. With the new gearbox, the
ZS-EG side devolatilization can be quickly and
easily converted into a ZS-B side feeder. Of course,
the same applies in the opposite direction: a ZS-B
side feeder can be transformed into a ZS-EG side
devolatilization in just a few movements.
