Effect of dust dispersion on particle integrity and explosion hazards

Anthraquinone, Acetaminophen and Ascorbic Acid show that even in the absence of an outlet valve, significant particle breakage occurs. This demonstrates the major role of both the dispersion nozzle and cloud turbulence in particle breakage. In addition, the experiments revealed dispersion concentration to be an important factor in particle breakage and helped establish the inverse relation between particle breakage and dust dispersion concentration. Nanomaterial experiments with CNFs show significant de-agglomeration in the dispersion cloud followed by re-agglomeration.
