Homogeneous Granulation of Powder Systems
Typical applications where Freeze Granulation provides homogeneous granulation and drying are engineering (advanced, fine, high-performance) ceramic powders; oxides such as alumina (Al2O3), zirconia (ZrO2), silica (SiO2), nitrides such as silicon nitride (Si3N4) and carbides such as silicon carbide (SiC). Additional applications are granulation of metals and metal oxides powders, making granules for plasma spraying or catalysis, processing of nanomaterials (nanopowders), diamonds (PCD/CBN inserts), LED Lighting and igniters, delay elements, drying of pharmaceuticals, drugs and biomaterials like proteins, enzymes and fine chemicals.
– for improved* granule properties compared with spray drying!
(*improved granule properties: Granules with no void formation, no migration of fine particles or binders, and no formation of hard dry shell).
