To ensure the desired properties, bioplastics compounding systems demand excellent dispersive and distributive mixing at moderate shear rates and low product temperatures.
The careful incorporation of fibres, fillers and additives often requires multiple metering of dry ingredient streams and possibly also the injection of liquid additives at defined positions in the compounding machinery.
The BUSS Co-Kneader’s specific capabilities are outstandingly suitable for such applications. Thanks to its operating principle, the enormous number of mixing cycles at moderate and adjustable shear rates enables the highest possible mixing efficiency over short processing lengths with narrow residence time spectra. The BUSS Kneader’s two-stage system systematically separates the compounding and pressure build-up stages so that each of them can be independently optimized.
The split barrel of the BUSS Kneader and the retractable casing of the discharge extruder ensure fast and easy access to the processing components for high system availability.
Together with broadly based BUSS process expertise in compounding, the modular design and therefore adaptable arrangement of the entire compounding line, make the BUSS Co-Kneader is first choice for compounding technical bioplastics.
