Abstract

Measurement apparatus of powder bed shear stress analyzer (NS-200) can measure the continuous shear force on a shared surface (friction force on a sheared surface) by simultaneously collecting data on the normal compression force. Powder properties (flowability (angle of internal friction), adhesion, compressibility and stress relaxation characteristics) of raw materials powder and semifinished product, used for toner, pharmaceutical compound, cosmetics and so on, can be evaluated with high precision and good reproducibility.
