In our field testing area we have various types of powder processing equipment to mimic powder unit operations on smaller scale. These equipments enable to process powder materials and granular matter in the sub-kilogram or lower kilogram range. In this way we can assist companies that are in the stage between lab-scale (grams scale) and pilot plant scale ( tens to hundreds of kilograms) and start-up companies that need product development opportunities in the kilogram range.
We offer product development by milling in ball mills or centrifugal mills; also cryogenic milling can be applied. Mixing can be attained by means of low shear to high shear mixers We can also work under inert conditions to avoid oxidation or impact of moisture. A Granulation process of powder to granules is available by a disc granulator or a high shear granulator set-up. Coating of solid matter is performed at ambient conditions or at higher temperatures depending on the materials processed. Pneumatic transport of powders and granules can be done in the test-up capable of executing dilute or dense phase pneumatic conveying. In the pneumatic transport experiments, also wear and attrition can be studied. Finally, we also have a 10 cm diameter fluid bed set-up to study fluidization of powder materials.
The strength of our approach is that we have our characterization possibilities at hand, so we can in any stage of the process test the quality and physical properties of the materials based on particle size, density, surface area, flowability and many other physical aspects.
