Ideal in the lower output range – conical twin-screw extruders from KraussMaffei Berstorff
The conical twin-screw extruders from KraussMaffei Berstorff are ideal for the lower output range, either as standalone extruders or for coextrusion. In this category, they offer critical design and process engineering benefits.
The short, compact design saves valuable production area – the angled alignment of the screw axes makes space for a rugged distributing gearbox and a substantial back pressure bearing. This machine design ensures optimal functionality even in relentless round-the-clock production. The relatively small screw diameter results in minimal back pressure forces in the metering zone, which contributes to the long service life of the back pressure bearings. The screw, specially designed for PVC processing, ensures extremely gentle plasticizing.

On double-conical screws the flight depth decreases
from intake to output zone. On conventional single-
conical screws, by contrast, the flight depth remains
constant over the whole length of the screw.
Uniform pre-plasticizing and optimal thermal
homogeneity
Single-conical screws can be double-flighted from
the intake zone to the compression zone. This
ensures uniform material processing. The shal-
lower flight depth in the intake and precom-
pression zones of single-conical screws means
that heat transfer from the barrel heating is
significantly better. In consequence, the powder
achieves optimal thermal homogeneity during the
pre-plasticizing phase.
Benefits of longer screws
The longer screws of the KMD 43 K/P and KMD
63 K/P guarantee a very stable process, optimal
melt homogeneity, a wider processing window for
different formulations, and pressure stability up
to 500 bar, with a constant conveying rate even
against high die resistance.

Coextruders for profile extrusion
The machines in our conical extruder series are
available as standard standalone extruders and as
coextruders for profile extrusion. Coextrusion is
an important trend in plastics processing. In profile
extrusion, a coextrusion solution can allow the core,
or other non-visible window parts, to be made of
cheaper regrind, with only a thin outer layer made
of colour-fast virgin material. Profile manufacturers
want space-saving coextrusion solutions.
Piggyback configurations save space
Combinations of parallel basic extruders and one
or two piggyback extruders are common. The
basic extruder processes the regrind, while the
coextruder processes the virgin material. Conical
extruders with a screw diameter of up to 63 mm
can be mounted above the main extruder, and
capable of movement in two axes. KraussMaffei
Berstorff offers a wide range of coextruders and
unique space-saving coextrusion concepts such
as post-mounted and piggybacked combinations.

DETAILED PRODUCT INFORMATION
The C5 control – one of the most advanced control and monitoring systems in the industry
Centralized control of the extrusion line
Meeting tough specifications for product quality and
output demands a stable, reliable production process.
This is where the C5 control system scores. As one of
the most advanced systems in the industry, it offers
dependable technology and intelligent functions for
centralized control and monitoring of extrusion lines.
For the operator, the C5 ensures optimal set-up and
start-up, and a clear, consistent overview of the pro-
duction process. Monitoring and control is facilitated
by efficient visualization of the status of different
extrusion line components on a series of screen pages.
Central synchronization of the whole line, including
multiple extruders, is fast and simple. The operator
panel allows direct intervention in the operation of
all key elements in the extrusion line. The current
operating status of the whole line is always displayed,
together with a customizable selection of seven actual
parameters. Prompts and alarm messages flash up
in your chosen language. The C5 offers extensive
documentation options and easy connection to a host
computer. The standard design features an integrated
operator panel; swivel-mounted or mobile panels are
offered as options. The swivel-mounted panel, for
example, enables the operator to run the whole line
from a position near the die.

CUSTOMER BENEFITS
Built-in economic and process advantages – it’s over to you to exploit them
Conical twin-screw extruders from KraussMaffei
Berstorff stand for productive, cost-effective profile
extrusion and process benefits. Our experience and
our ability to deliver outstanding solutions are at
your service.
Benefits that pay off
The drastic extension of the preheating zone in the
new KMD 43 K/P and KMD 63 K/P significantly
reduces shear energy input to the melt. The propor-
tionate increase in heat energy makes it possible
to control the entire process much more precisely
by controlling the processing unit temperature. It
also makes it easier to process different materials,
eg, dryblend, granulate or regrind. This greatly in-
creases production flexibility over the whole output
range of the machine. It also makes it easier to change
stabilizing agents if necessary.
The high-performance gear system allows the
specific throughput to be increased; this means
higher output for the same screw speed. The
longer screw and further improved screw geom-
etries ensure optimal melt homogeneity thanks
to gentle, uniform plasticizing. The proven,
self-regulating internal screw temperature control
contributes to uniform plasticizing, excellent melt
homogeneity and to a marked reduction in shear
energy, and ultimately to lower maintenance
effort. Molybdenum hard-facing is standard
on KMD 43 K/P and KMD 63 K/P screws. It’s
because the new conical machine generation are
universal workhorses, engineered for reliable
performance and productivity that they promise
excellent returns on your investment.
Your benefits at a glance:
· Optimal melt homogeneity thanks to long processing unit
· Wide processing window for different formulations
· Increase of specific throughput and output rates through extension of the preheating length; this results in higher output for the same screw speed
· Outstandingly consistent product quality over a defined performance range
· Low maintenance thanks to internally temperature-controlled screws and air-cooled barrels
· Cost savings from extended service life for the processing unit and high output rates
· Excellent price/performance ratio
