Small Ring Shear Tester RST-XS.s
The "small" automatic, digitally controlled Ring Shear Tester
RST-XS.s for the measurement of flow properties of powders
(flowability, caking, wall friction). Automatic,
computer-controlled test procedure. Very small specimen volume
(standard: only about 30 ml , smallest approx. 3.5 ml).
CAHD - Software for silo design for flow
CAHD: Computer-aided Hopper Design.
An interactive software doing the common calculations
according to A. W. Jenike's theory and, if desired, also
according to other approaches: Hopper slope for mass flow
(diameter-dependent), outlet dimensions to avoid arching and
ratholing. The entire process is user-controlled and
transparent: Diagrams, extrapolations, and so on, are finally
presented in a comprehensive document.
New: Small volume shear cell XS-Sr
The shear cell type XS-Sr for Ring Shear Testers RST-XS.s and
RST-XS with only 10 ml specimen volume is provided with a lid
and bottom ring design similar to the larger shear cells XS-Mr
