Homogeneous Granules by Freeze Granulation 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.… Continue reading How to make granules from powders

Nano Diamond Powder
Freeze Granulation is today being used for mixing, granulation and drying of nano diamond powders. The resulting granules have a homogeneous distribution of nano diamond particles, fillers, binders and nano pores. Please go to Contact and ask for more information and for a Test-Granulation.
Preparation of PIM or Extrusion Feedstock
Freeze Granulation of PIM or Extrusion Feedstock Powder injection molding (PIM) and extrusion are powder shaping techniques that typically involve preparation of high viscous feedstock making it difficult to achieve full homogeneity. Especially if the powders are fine (submicron or nano) and/or if it is a composite material. By doing an initial preparation of a low… Continue reading Preparation of PIM or Extrusion Feedstock
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.
Superabrasive grinding tools
Homogeneous 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 for more information and a test-granulation of your… Continue reading Superabrasive grinding tools
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
Nano ice formation in granules
Nano ice in granules by Freeze Granulation The formation of nano ice in the Freeze Granulation process is a key factor for the unique homogeneity of particles and binders achieved in the resulting granules. This is especially important for nanopowders, fine particles and binders where migration of these could occur during conventional drying, like spray drying. Please contact us for… Continue reading Nano ice formation in granules
Granulation equipment
PowderPro supplies equipment for granulation of various powders and chemicals. Freeze Granulation for improved granule properties compared with spray drying. Granules with no void formation, no migration of fine particles or binders, and no formation of hard dry shell. Spray cooling or rather called spray freezing is the first step in the freeze granulation process where a… Continue reading Granulation equipment
Transparent and translucent ceramics
Transparent and translucent ceramics by Freeze Granulation Freeze Granulation is today being used for commercial manufacturing of transparent and translucent ceramics. The main advantage is to achieve a homogeneous distribution of the starting material which will result in rapid reaction and sintering at low temperature where grain growth of the material will be avoided. Please… Continue reading Transparent and translucent ceramics
Freeze drying
Spray Freeze Drying for Soft Granules by Freeze Granulation Freeze drying is an important processing step in Freeze Granulation where we sublimate the solvent (ice if water) from our spray frozen (spray freezed) granules, resulting in a free-flowing and dust-free granulated material suitable for pressing of components. Please contact us for more information and a test-granulation of your powder system.
