Abstract: It is common practice in powder technology to run shear tests for characterizing the flowability of powders. To measure these shear properties the flow factor tester of Jenike is mainly used. In this apparatus the state of stress cannot be determined completely and assumptions regarding the position of slip planes are necessary to evaluate the test results. Therefore this apparatus is less applicable in research work to get more information on the stress-strain behaviour of powders. In order to make such work possible a new apparatus, based on the ideas of Roscoe, has been developed, in which the states of stress and strain can be determined completely. Test results from measurements with both apparatuses will be compared and it will be shown, how the different results influence the design of hoppers.
