Combining decades of experience in scientific instrumentation with fundamental research on powder characterization, we offer a unique set of complementary instruments for granular materials characterization, with strict initialization protocols, simple geometries and high level of automation.
With high quality instuments hand-made in Belgium, we strive to provide the highest quality by locally sourcing materials, assembling by hand, and ensuring scrupulous calibration and qualification by our team of skilled engineers.
Our measurements are designed to correlate with what happens in production, quality control and storage. They capture the physicochemical and rheological properties of metal, battery, pharmaceutical, food, ceramic, chemical and polymer powders.
We focus on four properties that drive powder behavior: flowability, cohesion, packing and electrostatic charging. Each one is measured with parameters grounded in powder physics and easy to interpret.
We follow a general principle for powder flow measurement: "The stress state and the flow field of the powder should be comparable in the measurement cell and in the process."
Our instruments mimic processes at a different scale. The complementary instruments are then combined into workflows to reproduce each step of the processes we want to characterize.
The combination of simple geometries and precision makes our instruments great candidates to calibrate numerical models with physical measurables. Particularly, we provide values for cohesion, friction coefficients, and electrostatics.
Granutools is compatible with several simulation software where characteristics such as the cohesive index or the slope index can be set as an input for simulation parameters.
