The effect of particle concentration on impeller speed necessary for mixing of fine suspension is presented in the paper. A curved three-blade turbines with vessel to impeller diameter ratio Did = 2 were used in experiments. Measurements were carried out in a cylindrical baffled vessel with the diameter of 300 mm. Glass particles of four equivalent diameters between 0.18 and 0.89 mm and volumetric...
Celem niniejszej pracy jest porównanie procesu wytwarzania zawiesin przebiegającego w standardowym zbiorniku H - D oraz w zbiorniku o większej smukłości (H = 2D), z większą liczbą mieszadeł różnie rozmieszczonych. Analizowano obecność cząstek stałych na dnie zbiornika, granicę rozdziału zawiesina - ciecz oraz rozkład stężeń na różnych poziomach zbiornika. Przedstawiono kilka sposobów zwiększenia jednorodności...
