New software for the FT4 Powder Rheometer, the universal powder tester from Freeman Technology, demystifies hopper design, guiding the user step-by-step through powder measurement, data analysis and equipment specification. Relevant to a broad range of industries, the new software provides a cost- and time-effective solution for hopper and bin specification. The fully automated FT4 measures all the parameters required for hopper design with unprecedented precision. The software determines critical hopper parameters from this data using well-established design methodologies. A testing and design cycle is typically complete in around two hours.
