GRANULATION STATE DETECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a granulation state detection method capable of accurately detecting a granulation state without time delay. SOLUTION: When sticky powdery particles are agitated and granulated in a granulator 1, the relationship between a resistance value corresponding to the agitation resistance of the particles in the granulator 1 and a granulation state corresponding to the degree of progress of granulation is previously derived. A value corresponding to power required to rotationally drive a member 6 which rotates in the flow region of the particles in the granulator is measured as the resistance value. The granulation state is detected from the measured resistance value and the previously derived relationship. COPYRIGHT: (C)2004,JPO
