Powder tester for simple powder characterisation
Freeman Technology has launched the stand alone Uniaxial Powder Tester (UPT) for simple, sensitive and cost-efficient powder characterisation. The tester measures unconfined yield strength (UYS), a parameter derived indirectly via biaxial shear cell analysis, which is widely used to assess and rank the cohesivity of powders. Uniaxial testing involves the construction of a consolidated powder column, which is then fractured through the application of a vertical stress to directly measure UYS known as a σc. Key to the successful implementation of the technique is the construction of a uniformly consolidated powder column, and subsequent removal of the containing sleeve with minimal disturbance of the compacted column.
The instrument is available in either a manual or an advanced version. Both deliver the same data with the same high repeatability, but the advanced version has the advantage of higher levels of automation and lower manual input for customers that require it.
