New large Ring Shear Tester available soon
We are proud to present the Ring Shear Tester RST Mk II
(image above) which is the successor to model RST-01.pc. It
will be upwardly compatible with its predecessor (e.g.
usability of the same shear cells), but will be somewhat
smaller and lighter.
With the tester, the new software RST-CONTROL v3 is
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 powder testing procedure. Very small
specimen volume (standard: only about 30 ml, smallest approx.
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 and extrapolations are finally presented
in a comprehensive document.
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
Shear cell and driving axle with reduced heat transfer
This new accessory for the Ring Shear Tester RST-XS.s design
supports tests at temperatures deviating from room temperature
(reduced heat transfer, increased heat capacity).
Optimized design of shear cells for large ring shear testers
RST-01.pc and RST Mk II
A new generation of shear cells for the large ring shear
tester RST-01.pc and its successor RST Mk II offers advantages
in terms of cleaning and handling. Available with a sample
volume of 900 ml, 200 ml and 48 ml.
