Relationship between residence time distribution and forces applied by paddles on powder attrition during the die filling process

The die filling process, which happens prior to the compaction step, affects directly the quality of the final product (tablets). As paddles pass through the powder bed inside the feed frame, shear is applied to particles. Therefore, it is important to establish a relationship between residence time distribution (RTD) and forces applied by the feed frame paddles on powder attrition and overlubrication during the die filling process. The pulse...
