Sub Sieve Autosizer

The H.E.L. Limited Subsieve AutoSizer (SAS) is a new addition to the established field of air-permeability particle sizing. It has been developed as a direct and improved successor to the widely used Fisher Model 95 Sub-Sieve Sizer (FSSS). The SAS adds automated functions, and electronically recorded and presented data, to an established particle sizing technique. The SAS uses the principle of pressure drop across a packed bed of powder. By varying the sample height, and hence the “porosity” of the bed, average surface area and particle size can be determined as a function of pressure drop in accordance with the Carmen equation. The SAS measures particle size in the range of 0.2 µm to 75 µm and has a compression accuracy of less than 0.05 mm.

Particle size analyzers have rendered results with the assumption that all particles are spherical. However, not all particles are spherical. Particle shape information about raw materials enables manufacturers to control their process with a much higher level of sensitivity. The Particle Shape Analyzer is a dynamic image analyzer which is ideal for applications where the particle shape, not just the diameter, is critical information.
