Chemical Technology, Control and Management


Article is devoted to determination of critical speeds of a compound from solid bodies with sharply different physicomechanical properties in a three-phase fluidized layer. Critical speeds, in particular, the speed of ablation of wab of a thin skin of root crops, in the form of a thin plate of irregular shape are defined. Results on critical speed of ablation considerably differ from the estimated values received on a formula Todes O.M. Therefore, for increase in accuracy of determination of critical speed of ablation of a three-phase fluidized layer the correlation considering a factor of the form and sailing of bodies of irregular shape is entered into a well-known criteria formula. The error of the received formula does not exceed ±5%.
