Homogeneous composite powders are beeing made by Freeze Granulation of a homogeneous composite powder slurry.
PowderPro AB provides equipment for Freeze Granulation in two versions, LS-2 (see photo) and LS-6. The maximum granulation capacity of LS-2 is 2 litres slurry per hour and for LS-6 6 litres slurry per hours that typically correspond to ca 2 and 6 kg dry powder respectively.
LS-2 and LS-6 consists of a slip container with a stirrer, a pump for the slip, a spray nozzle, a regulator for compressed air and an insulated chamber for spraying and granule collection. Technical Specification LS-2
Besides the granulator, a freeze dryer (see photo of Lyovac GT-2 below) with sufficient capacity is required and can be provided. Technical transfer including set-up of equipment and training of personnel is recommended and offered upon request.
