A wide range of applications, a large process window, high flexibility and robustness as well as improved process stability, but also operational and user safety, energy efficiency and reduced operating costs – these are the market requirements that the new compounding system COMPEO from BUSS meets. The innovative concept of the new COMPEO compounder system consists of various components. On the one hand, there is the modular machine concept that makes the series so flexible. You could inform yourself about this in the previous newsletter. Today we present the next component that ensures maximum compounding efficiency: the new COMPEO discharge concept.

The innovative COMPEO series discharge unit uses the conveying stability of a screw pump, offering ideal pressure build-up for downstream units.

COMPEO – efficient with an innovative discharge concept

The COMPEO discharge unit ensures high overall compounding efficiency. It builds up the required pressure for downstream units such as screen changers and pelletizers optimally and reliably, independent of the mixing step in the compounder. It is based on the principle of a conical twin-screw extruder and is run in a metered mode. As a result, the entire pressure build-up takes place in the slowly rotating twin screw, which prevents temperature increases at the transition from the compounder to discharge. The working principle of a screw pump ensures that even with higher maximum conveying efficiency, also in case of higher back pressure, which means that the RPM and an associated temperature increase in temperature can be minimized.
