ANDRITZ delivers custom designed ceramics and polyethylene materials as well as proprietary designed blades and engineered drainage systems. Our products are the highest quality and suited for all paper machine designs and paper grades.
The type of ceramic and blade design plays a critical role in the overall operation and efficiency of the wet end of the paper machine. The ceramic properties which are important to their performance are wear resistance, gentleness to fabrics, chip resistance, thermal shock resistance and thermal conductivity. ANDRITZ applies the engineered approach to replacing foil blades and covers by exploring alternative designs and materials to improve your machine’s performance.
