Drawing on the characterization capabilities of the FT4 Powder Rheometer, the new software package improves access to well-established hopper design methodologies, speeding up and simplifying compilation and interpretation of the required data. The two criteria defining the limits of a bin to operate in mass flow mode are outlet size and hopper half angle. Both are calculated using data generated from shear cell, wall friction, and compressibility testing. All the required data can be generated simply and easily using the FT4 in a series of fully automated measurements taking approximately two hours. The new software, which will become part of the FT4’s standard data analysis package, is supported by a step-by-step guide to hopper design, simplifying what has traditionally been a complex process.
