News on how Freeze Granulation can improve our powder properties

Carbon nanotubes (CNT)

Freeze Granulation of Carbon Nanotubes (CNT)

By using Freeze Granulation it is possible to disperse and avoid agglomeration of Carbon Nanotubes. Carbon nanotubes can be granulated and dried into a powder and then re-dispersed to nanopowders again avoiding agglomeration (aggregates) of nanoparticles, which is not possible with other granulation methods like spray drying.

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.

Synthetic diamond powder granulation

Homogeneous diamond tools by Freeze Granulation

Synthetic diamond powder granulation is today being formed by Freeze Granulation for to make homogeneous granules for diamond tools with long tool-life and optimal performance. Please contact us for more information and a test-granulation of your system.

POWTECH 2013 – Nürnberg

Second day @Powtech 2013 in Nürnberg, spring in the air! Good and interesting meetings on powder processing and how Freeze Granulation can improve the homogeneity of the granules, for example nanomaterial like CNT – Carbon Nano Tubes.

Please contact us for more information and a test-granulation of your powder system.

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.

ECerS XIII Conference – Limoges

PowderPro will have a stand at the exhibition at ECerS XIII Conference (European Ceramic Society) in Limoges, France from the 23rd to the 27th of June 2013. We look forward to meet costumers, partners and new contacts for interesting discussions in our stand!

We plan to have our equipment available for you to see the process of Freeze Granulation.

How to make granules from powders

Homogeneous Granules by Freeze Granulation

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 50-300 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.

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 viscous (based on water or organic) suspension the powders can be properly de-agglomerated, dispersed and homogenized. Other constituents aimed for the PIM or extrusion process can be added prior to freeze granulation. The result will be a homogenized, soft and dust free powder, easy to mix and disperse into a feedstock for PIM or extrusion at high powder concentration and homogeneity, promoting sintering and ultimate material performance.

Please contact us for more information and a test-granulation of your powder system.

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.

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.
