Freeman Technologies: Powder Rheometer
October 24, 2001
The FT3 powder rheometer from Freeman Technologies provides a revolutionary means of assessing the flowability and processability of powders. The complexity and inherent changeability of powders makes their characterization notoriously difficult, and the FT3's novel approach is designed to overcome the problems of traditional methods of assessment. The FT3 evaluates flow properties in a small sample of material (10-300 ml) by first pre-conditioning it to produce a consistent bed, and then measuring the torque, force and energy in the test chamber as a blade traces a precise helical path through the powder. Standard programs are automated and produce highly repeatable results in a few minutes. The resulting data provide flow rate and compaction indices, numbers that define the key variables affecting flowability.
