The pressure drop in the hydrocyclone is an important item together with its performances, because the pump, which is used for the hydrocyclone, must be selected according to the pressure drop, and the necessary energy depends upon the pressure drop and the liquid quantity. The author has measured the pressure difference between the inlet and the overflow pipe under the various operating conditions. The influences of the following factors upon the pressure drop were investigated : (1) Feed inlet velocity v_i, (2) Diameters of vortex finder D_o, underflow nozzle D_u and cylindrical portion D, (3) Dimension of inlet nozzle √<bh>, (4) Height of cyclone H, (5) Inserted length of vortex finder S, (6) Types of feedins, (7) Pulp density of feed slurries δ_f. From the above experimental results, author has shown that the pressure drop through the cyclone may be represented by the formulae (4・2).
