Scale-up of mixing equipment fo suspensions
Original language description
To be able to use the results for design of industrial mixing equipment, knowledge of scale-up rules is necessary. Therefore, an experimental verification of scale-up rule is the main aim of present paper. Experiments were carried out in three perspex vessels with flat bottom of inner diameters D=290, 600 and 800 mm. The TX 335 agitators were used in measurements. For suspension measurements electrochemical method of determination of just suspended impeller speed was used. Glass particles with four equivalent diameters dp between 0.16 and 1.19 mm and volumetric concentration c from 2.5% to 20% were used as solid phase. From the results presented it follows that just-suspension speed calculation of industrial agitator from dimensionless dependence of modified Froude number on relative particle size dp/D and volumetric particle content c measured on geometrically similar model of laboratory scale is acceptable. It was also found that scale-up rule depends significantly on particle concen
