Markets
PowderPro has sold equipment and services for freeze granulation to companies, institutes and universities world wide since 2000. Representation in China, India, Japan, Korea, and USA. Typical applications are for granulation of ceramic powders; oxides (Al2O3, ZrO2, SiO2), nitrides (Si3N4) and carbides (SiC) and also metal oxides, nanopowders, diamonds/CBN, explosives (igniters, delay elements) and for drying of pharmaceuticals and drygs and for drying of biomaterials like proteins and enzymes and fine chemicals.
