Updated Buss Kneader optimises
cable compound production
Buss AG from Switzerland has updated its
MX 105 compounding line for processing
highly filled or crosslinkable halogen-free
flame retardant (HFFR) cable compounds,
optimising it in many respects. Thanks to a
simplified design, this system which is capable
of handling throughputs of up to 1500 kg/h
now has a particularly advantageous priceperformance ratio without compromising
on functionality, machine operability or
achievable product quality. BUSS has also
made the machine quieter and more energy
efficient.
The hinged process section now opens even
wider to 120 degrees, providing unprecedented
accessibility and further enhancing ease of
maintenance and operation.
The redesigned, compact discharge extruder
with a fully retractable pelletiser stands out
by its greatly reduced footprint. The discharge
screw is now electrically heated and air-cooled,
so simplifying the line in comparison with the
previous oil heating system, while simultaneously
increasing safety and operational reliability.
Moreover, a screen changer can now also be
retrofitted.
The MX 105 is the mid-range model of the MX
series, is available with a processing length of
15 or 22 L/D and can be fitted with two or three
feed hoppers. For processing semi-conductor
compounds or carbon black masterbatches, the
discharge extruder can be replaced by a melt
pump.
The pelletiser’s three-blade knife arm ensures
excellent cutting quality at moderate speeds. The
new arrangement of the knife drive improves
accessibility, simplifies operation and boosts
operational reliability in this area too.
The Buss MX series is fitted with SIMATIC-S7
or, with immediate availability, also with Allen
Bradley control systems. User interface options
include SCADA solutions with Simatic WinCC or
GE-Cimplicity, while control panel options include
the SIMATIC TP 2200 Comfort and the Allen Bradley
Panel View series.
The optimised toothing of the new, combined
reduction/stroke gearbox offers greater efficiency
together with lower noise. The electric drives
of the Buss Kneader and discharge extruder are
designed to operate at motor speeds which are
above 70% of nominal speed while outputting
at least 50% of rated torque, so ensuring they
achieve efficiency of at least 90%.
