Impellers and Agitation Systems

Blending PH blend time and degree of homogeneity flow velocity surface entrainment or agglomeration prevent air entrainment Flow characteristic (Newtonian / non-Newtonian) [Pg.249]

Suspensk w jn 1 homogeneous suspension or off-bottom suspension sufficient restarting in settled sediment particle size solids concentration liquid and solids density [Pg.249]

D spe rsic n required conversion or mass transfer gassing rate superficial gas velocity mass transfer coefficient local / global specific power input required stoichiometric excess of reacting gas [Pg.249]

3t trans l rer temperature difference at process start / end required heating / cooling time local / global heat transfer coefficient specific heat capacity and heat conductivity of the product [Pg.249]

Agitators or agitation systems usually have to fulfill a combination of the following objectives during crystallization [Pg.249]
