MX 105 Compounding Line
Optimizes Cable Compound Production
Buss AG, Pratteln, Switzerland, has updated its MX 105 compounding line for processing highly filled or crosslinkable halogen-free flame retardant (HFFR) cable compounds, optimizing 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 price-performance ratio without compromising on functionality, machine operability or achievable product quality. Buss has also made the machine quieter and more energy efficient.
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 optimized 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 %.
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 pelletizer 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 pelletizer'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.
