Freeze Granulation is today used for commercial production of homogeneous granules for the production of oxides used as a ceramic phosphor plate for white illumination in LED Lighting. By using Freeze Granulation of the powder and binder mixture, compared with spray drying, it is possible to manufacture a homogeneous phosphor plate with optimal properties for to generate a soft and warm white light from high power LEDs.

Ultrasonic atomisation
Freeze Granulation can be made using ultrasonic atomisation of the droplets. The resulting granules have a narrow granule size distribution and the granule size is in general smaller (average 120 micron) compared to a regular spray nozzle. The granulation speed is also slow with about 0.3 to 0.5 litre/h.
Abrasive granulation
Freeze Granulation is today beeing used for commercial mixing, granulation and drying of different abrasive products. The resulting products have a homogeneous distribution of all active material, like superabrasive particles, resulting in improved milling performance and long tool life.

Granule shape, size and density
Freeze Granulation provides spherical free-flowing dust-free granules without cavities in the size range of 20-500 micron. The solids content of the suspension (slip) and the processing parameters (pump speed and airflow) control the granule density and size.

Granule homogeneity
Migration and segregation of the constituents that is common in other granulating processes such as spray drying is avoided in Freeze Granulation. By instant freezing of small droplets critical ice crystal growth is avoided. The freeze drying where the liquid medium is sublimated ensures homogeneity preservation, limited oxidation and soft bonds within the granules. This provides the best possible condition for any subsequent processing such as easy pressing to homogenous compacts, easy re-dispersing in a liquid, sintering of catalytic particles, dosage processes etc.
