By using Freeze Granulation or Spray Freeze Drying it’s possible to make spherical, homogeneous and dust-free granules with optimal flowability which is critical for automatic uniaxial pressing of for ex ceramics and metal powders.
You can expect spherical and homogenous granules of powders in terms of distribution of particle size and other possible additives you want to use. The granules with a size distribution in the range of 20-700 microns will have weak inter particle bonding making them easy to break down in pressing or re-disperse into another formulation. Very much depend upon how you intend to process the powder and depending on that, adaptation can be made.
Please contact us and we will further discuss the opportunities with Freeze Granulation on your powder system and read more on technology and we propose a Granulation Test of your powder system.
Spherical, dust-free, homogeneous granules – no donuts!
