Summary This report documents the work performed during the last 36 months funded by IFPRI. It covers the following four aspects: 1) suction filling; 2) Rotary die filling; 3) Forced die filling with a paddle wheel; and 4) Segregation during die filling. For suction filling, a model suction filling system was developed. Die filling efficiency was evaluated in terms of fill ratio, and four different types of pharmaceutical powders were used and. Effects of filling and suction velocities, as well as powder properties, on the efficiency of die filling were systematically investigated. It...
