New software simplifies hopper design

Freeman Technology of Welland, Worcestershire, UK, has devised new software for its FT4 powder rheometer which is said to facilitate hopper design, guiding the user step-by-step through powder measurement, data analysis and equipment specification. The software determines critical hopper parameters from measurements of shear cell, wall friction and bulk density to help specify the correct size of outlet aperture and hopper geometry. www.freemantech.co.uk
