The Ring Shear Tester RST-01.pc provides computer-controlled measurement of the flow properties of powders and other bulk solid materials, under conditions which duplicate handling situations. Such properties are useful for many applications: Product development, product characterization, quality control, comparative tests, troubleshooting, or silo design.
Automatic measurement means that the test is performed following a well-defined procedure, which is executed computer-controlled. Further measurements provided by the tester are wall friction tests (friction between a powder and the surface of a solid, e.g. the wall material of a hopper) and compressibility tests. The tester can even be used to measure the attrition properties of materials such as granules, flakes and pellets.
The Ring Shear Tester RST-01.pc is extremely versatile. Materials which are free flowing, very poor flowing, or require large shear deformation can all be tested. The applied stress level can be varied over a wide range, consistent with how your material is being handled. Shear cells of different volumes allow the testing of limited quantities of your material.
The Ring Shear Tester RST-01.pc is controlled by the software RST-CONTROL 95. The software provides several test modes. Standard procedures can be used, where test parameters are entered once. Thus, the operator can start a test just with some mouse clicks. For special applications a semi-automatic test mode is provided. Here the operator observes the measured data on the screen and controls the test via the PC keyboard or the mouse. The software package additionally contains the program RSV 95 for the detailed analysis of the test data and for the output of the results, e.g. as diagram, table or report, with the possibility to export the data/diagrams to other applications (e.g. word processor, spreadsheet).
