The Effect of Very Cohesive Ultra-Fine Particles in ...

This paper focuses on the effect of ultra-fine ( d < 10 µm) powders in mixtures with fine ( d < 100 µm) bulk material on compression processes and also evaluates the re-fluidization behavior of the compressed bed (history effect). Achieving this goal, different mixtures of fine and ultra-fine Ground-Carbonate-Calcium were compressed at three pressure levels.

The PM 1 sensor module works on the physical principle of laser scattering, also known as optical particle counter (OPC), measures dust particles illuminated by laser light at a 90° angle. The light scattered from each particle is collected at approximately 90° by a mirror and detected by a photo-diode. After that, the signal is fed into a multi-channel size classifier where a pulse height ...

Ultrafine particle - Wikipedia

Ultrafine particles (UFPs) are particulate matter of nanoscale size (less than μm or 100 nm in diameter). Regulations do not exist for this size class of ambient air pollution particles, which are far smaller than the regulated PM 10 and PM particle classes and are believed to have several more aggressive health implications than those classes of larger particulates.
