Abstract：For investigating the feasibility of measurement of polypropy lene powder by using CAMSIZER， the particle size distribution of polypropylene powder has been measured with CAMSIZER， meanwhile the functions of CAMSIZER， particle roundness and image measurement， have been validated. The results show that the particle size distribution of polypropylene powder can be measured with CAMSIZER with very good reproducibility and very fast. In addition to the size characteristics， the CAMSIZER results allow to measure the roundness and projection image of the particles.
