BUSS PCS Co-Kneaders

The specialist for powder coatings & thermosets

BUSS compounding technology developed further for optimized performance

The PCS is a further development of the classical BUSS Co-Kneader, specifically for the use of powder coatings and thermosets. While it retains the proven operating principles of the BUSS Co-Kneader, the process section in particular has been developed for the requirements of modern formulations.

The extended BUSS Co-Kneader series PCS sets benchmarks for profitability, availability and user-friendly handling. Its extended process length and increased screw speed enable optimum quality powder coating formulations with the same configuration, simply by adjusting the process parameters.

BUSS PCS Co-Kneaders are also highly suitable for processing thermosets. In order to exploit the superlative qualities of EMC, compounding systems must ensure excellent dispersion of the high filler content at low and perfectly controlled temperatures.

BUSS compounding technology has routinely met these high requirements for 60 years and is equally ideal for epoxy-based, phenol-based, polyester-based, melamine and urea-based resin molding compounds.

Our long-standing experience enables the optimum selection of the materials in order to minimize machine downtimes and maintenance work.

BUSS PCS Co-Kneader series

The solution for powder coatings and thermosets

With its combined screw rotation and axial movement of its Co-Kneader screw, the BUSS Co-Kneader achieves intense distributive mixing which generates extensional flow, a large number of shear interfaces and cross-channel mixing. The melting and mixing energy input is almost exclusively mechanical.
Moderate shear rates enable controlled mixing at low temperatures, whereby only the shearing required for the respective task is applied. Narrow shear rate distribution ensures even shear rates for each individual particle. This results in high-quality preparation with reduced energy expenditure.
The BUSS Co-Kneader technology has been well-known for precise temperature control for more than six decades. The controlled energy input is due to uniform shear rates combined with precise temperature monitoring by thermocouples located in pins at any desired position along the process section.
High filler loading is enabled via additional inlet openings, split filler material feed, the removal of air inclusions via back venting and excellent transport efficiency. The moderate shear rates allow perfect handling of the highest viscosities for such high filler loading.
Kneading elements and pins from novel tungsten carbide alloys ensure excellent performance for high-wear applications such as EMC. Their service life is considerably longer than that of components made of conventional wear-resistant materials.
