Freeze Granulation produce flowable and crushable (soft) granules
Freeze Granulation produce flowable and crushable (soft) granules suitable for die pressing applications. Spray drying yield flowable, but hard granules which are difficult to cruch during die pressing. 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… Continue reading Freeze Granulation produce flowable and crushable (soft) granules
Can you make spherical granules?
Yes, with Freeze Granulation 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… Continue reading Can you make spherical granules?
Homogeneity preservation from suspension to dry granule
If you are looking for optimal homogeneity in your granulated material, then you should evaluate our unique granulation technology – Freeze Granulation! Today, Freeze Granulation is the only granulation technology that will preserve the homogeneity from suspension to dry granule, which is crucial for good results in most processes. Spray cooling or rather called spray freezing… Continue reading Homogeneity preservation from suspension to dry granule
Superabrasive Grinding Tools
Superabrasive grinding tools by Freeze Granulation Freeze Granulation is today being used for the production of high quality superabrasive grinding tools, where the superabrasive grains are homogeneously distributed in the grinding tool. This results in a grinding wheel with higher grinding capacity and longer grinding and cutting tool life. Please contact us and we will further discuss… Continue reading Superabrasive Grinding Tools
How to make granules from powders
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.
Granule drying
In the Freeze Granulation process, freeze drying/lyophilizing is used as the granule drying method for to sublimate the nano ice and there by avoid melting of the frozen granulate. Please contact us for more information and a test-granulation of your powder system.
Wet granulation
Freeze Granulation – homogeneous wet granulation of powders Freeze Granulation is a wet granulation method where the powders, chemicals and binders are first mixed and dispersed in a solvent. In the next step the homogeneous slurry is pumped and sprayed through a nozzle to form droplets, which are sprayed into liquid nitrogen for instant freezing.… Continue reading Wet granulation
Freeze Granulation of ceramic powders
Freeze Granulation offers the possibility to produce very soft, spherical granules which show an excellent flowability. The granules can be compressed to compacts of high homogeneity and they are completely redispersable. Freeze Granulation is a granulation technique which combines the advantages of spray drying and freeze drying. Hard granules are prevented by this technique excluding… Continue reading Freeze Granulation of ceramic powders
Applications for Freeze Granulation
Typical applications for Freeze Granulation are homogeneous granulation and drying of engineering (advanced, fine, high-performance) ceramic powders; oxides (alumina (Al2O3), zirconia (ZrO2), silica (SiO2)), nitrides (silicon nitride (Si3N4)) and carbides (SiC) and also granulation of powders of metal oxides, plasma spraying, nanomaterials (nanopowders), diamonds (PCD/CBN inserts), LED Lighting, pyrotechnicals (igniters, delay elements) and drying of pharmaceuticals and drugs, and for drying… Continue reading Applications for Freeze Granulation
