In view of the fact that a hydrocyclone is essentially a classifier, performance tests were carried out using an experimental unit. To evaluate the results of classification the method of Tromp's distribution curve is applied in relation to the particle size. This paper gives the results of the work, including some suggestions with respect to the cut size d_T, i.e. d_T is a 50% particle size in the above distribution curve. The influences of the following factors upon the cut size d_T 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) Pulp density δ_f and specific gravity s of feed slurries. In addition to the above results, the author has shown the following theoretical formula : cut size d_T may be expressed as equation (4・2).
