Pilot line for direct extrusion

The availability of free flowing polymers offers the rubber industry the opportunity to introduce continuous compounding, as it is already known from the processing of thermoplastic materials. From the economic point of view this becomes interesting if process steps can be summarised and eliminated. The concept of the direct extrusion line is the integration of the functions of 'compounding' and 'extrusion'. The combination of a continuous compounding device (chosen based on the results of an independent machine concept screening for continuous compounding) and an extruder had been tested for hose production.

A study on the costs for continuous compounding and batch mixing had been performed and published. Furthermore the different concepts for polymer grinding and the related costs have been analysed. An on-line rheometer for the continuous indication of the rheological properties has also been developed and tested for the pilot-compounding line.
