Ceramic Cutting Blade
Ceramic Fixed Blade
Ceramic Bed Knife
Made by ceramic material with ceramic perforations
It is mainly used in cutting polyester granular in the chemical industries. It can perfectly match with the underwater granular-cutting machines, which produced by Gernan Rieter Automatik GmbH or other factories.
