抄録

A new technique of evaluating the friction characteristics of a powder bed is described. A rotary-type rheometer with conical rotor was employed to measure the torque variation curves as the intruding distance of the rotor into the powder bed. The apparatus were evaluated using a standardized viscosity oil, and the shearing stress at an arbitrary intruding distance into the powder bed was converted into the apparent viscosity coefficient η_a. The relation between η_a and the void fraction of the powder bed were discussed based on Andrade's equation. It has been demonstrated that the measuring system and evaluating method presented here are effective for sensing of slight changes in the surface conditions in mixing of powders.
