Freeman Technology presents paper at French national powder conference discussing the measurement of shear properties of both consolidated and non-consolidated powders
A paper by Reg Freeman, managing director of Freeman Technology, presented at the French National Symposium on Powder Science and Technology (23-25 May 2007; Ecole des Mines d'Albi, France), examines the measurement of shear properties for consolidated and non-consolidated powders.
The paper is entitled 'Measuring shear properties and normal stresses generated within a rotational shear cell for consolidated and non-consolidated powders' and reports work carried out using the company's FT4 powder rheometer.
This universal powder tester characterises powders using dynamic methodology complemented by shear testing and the measurement of bulk properties.
Of particular interest in the paper is the relatively new area of study investigating very lightly stressed powders using shear cells.
The French National Symposium on Powder Science and Technology brings together scientists, process engineers and material scientists working in all the domains involving the industrial use of powders and finely divided solids.
These include the chemical, pharmaceutical, and food industries as well as ceramics, powder metallurgy, and cement, as well as the fundamental physics of granular media.
