fine and ultrafine particle characterization and modeling

2009-2-1 · In this study, an experimental investigation was carried out on fine and ultrafine metallic dust emission during high-speed milling of 6061-T6 aluminum alloy in wet and dry conditions. Measurements of dust emission were conducted using a scanning mobility particle sizer spectrometer and an aerodynamic particle sizer spectrometer. These instruments were used to characterize particles in the

jet milling conditions impact on wheat flour particle size

2021-4-1 · Particle size reduction is an ineffective process, regarding energy consumption. Actually, only the 0.1–2% of the supplied energy is used to reduce the particle size of the solids (Richardson et al., 2002). In order to save energy, optimization of milling processes is recommended (Ishito et al., 2002). Thus, many researchers focused on
