Bulk Solids Flow Properties
Laboratory shear testing.
Bulk Solids Flow Properties - Laboratory and onsite testing for shear, cohesion, time consolidation, density, wall friction unconfined compressive stress, tensile strength, fluidisation - permeability - dearation. For classification of powders, equipment and systems design, quality control and specifying for purchasing of materials. Silo and Hopper design. Design for mixing, avoiding segregation, avoiding agglomeration, avoiding degradation, avoiding caking, heating and cooling. That discharge and / or blend free flowing and cohesive products to very high accuracy, with flow control and shut off capability. Integrated with PLC control, discharge systems can provide variable flow regime from ideal flow, mass flow, eccentric flow and funnel flow. Easily retrofitted to existing silos and hoppers if required.
The behaviour of a powder or pouring good must want to judge objectively and qualitatively to be able to influence flow properties specifically.
To this basic mechanisms should be known. The measurement results, won from rotation-shear -testing. Peshl-Shear testers are founded physically and practice tested in a years of intensive research in the laboratory of the DMT as well as comparative tests of the TU Clausthal-Zellerfeld and with Lund University in Sweden.
