摘要：

Literature equations for calculating the minimum fluidization velocity of binary solid mixtures have been reviewed, and their capability to give a realistic interpretation of the fluidization behaviour of such systems discussed. For well-mixed beds of two solids of equal density, measured values of U(mf) can be successfully correlated by means of a classical equation such as Carman-Kozeny's, if their packing properties are correctly accounted for and proper average particle diameter is assumed. On this basis, the lowering effect of the addition of a small amount of fines on the minimum fluidization velocity of a bed of coarser particles can be explained.
