Ring shear testers series RST-01 and RST-XS

The Ring Shear Testers serve for the determination of the flow properties of more or less all powders and bulk solids like flour, cement, soap powder, titanium dioxide, clay, sewage sludge, and others. Our Ring shear testers are applied in a wide range of industry (e.g. Chemical Industry, Pharmaceutical Industry, Food Industry), and in universities and research institutions.

Flow properties are: flowability, internal friction, time consolidation, wall friction, and bulk density. More about these terms you will find in an essay on this website (click here) and - somewhat shorter - on an information sheet which can be downloaded here as pdf file.

Typical applications for the ring shear testers are, for example, product characterization, quality control, comparative tests, and silo design.


	The Ring Shear Testers of the RST-01 series are suited for all powders and bulk solids up to a particle size of 5 .. 10 mm. The basic version is the RST-01.01 (image on the left) where an operator is required during the test. The Ring Shear Tester RST-01.pc (image on the right) performs the tests automatically, i.e. controlled by a Personal Computer.
The "small" Ring Shear Tester RST-XS (see image below) is first of all an automatic flowability and caking tester for fine-grained powders.
	The RST-XS can be placed on the laboratory bench and is very easy to operate. Because of the small required powder specimen (only about 30 ml for the standard shear cell, about 3,5 ml for the smallest shear cell) this tester can be applied also in industries where only small amounts of powder are available for testing, e.g. in the Pharmaceutical Industry.
