SSSpinTester - Powder Strength Tester

 Powdered metals  An optimal powder is one that has enough cohesion to prevent segregation, but not enough to cause density variations. Obtaining strength values at low consolidation pressures allows prediction of optimal powdered metal behavior. The SSSpinTester can measure the strength of heavy metal powder at actual fill pressure values for direct correlation to processing conditions.
 Additives
 (for energy)
Additives are typically introduced to coal combustion streams through pneumatic conveying. The strength of the powder often determines how it flows through the system. Measuring the strength of these powders at low to moderate compaction pressures can help with conveying this material.
 Ceramics Density variations of sintered ceramic powder can cause significant problems with dimensional tolerances of the final parts. Filling pressures are very low and the density variations depend on the strength of the material. Segregation can be prevented by the cohesive properties of the bulk. The SSSpinTester can help avoid an off-spec product by measuring the strength of the ceramic powder at actual fill pressure values for direct correlation to processing conditions.
 Pharmaceutical Strength testing during formulation of pharmaceutical API powders is possible when only a very small quantity of the material is available. Tablet presses, for example, fill die cavities at very low pressures and then are compacted to very high pressures. The weight variance from tablet to tablet is directly related to how the die fills. The filling depends on the strength of the material at low pressures. The SSSpinTester can provide data at actual pressures. 
 Food
(fine powders only)
Food engineers need a quick test to measure the cohesion properties (strength and density) to determine if a particular mix will cause flow problems in the unit operation being used at the food plant. The SSSpinTester offers a fast and accurate measure of material strength at a full range of consolidation pressures. 
 Chemical Often an engineer wants a quick test to measure the cohesion properties (strength and density) of a particular formulation. Chemical mixtures may also be experiencing segregation and/or density variations in the process. The optimal powder is one that has enough cohesion to prevent segregation, but not enough to cause density variations. The SSSpinTester offers a fast and accurate test to measure cohesion properties that allows quick veriἀcation of the chemical formulation’s behavior in the existing or proposed system.
 Catalysts Measuring the strength of catalyst material at low consolidation pressures can allow the scientist to determine if a catalyst will channel and correlate this information to the life of the catalyst in a fluid bed.  The SSSpinTester measures the cohesiveness (strength and density) of the catalyst powder at actual process operating conditions, thereby avoiding messy manual extrapolation which is inherently inaccurate and time-consuming. 
 Cosmetics Decisions can be made regarding the size and shape of the powdered ingredients to optimize packaging success. The SSSpinTester can give the formulator and process engineer the data at actual pressures that are needed for successful packaging. Until now, they have had to test at much higher pressures and then extrapolate the data to real-time processes.
