On the third report, from the practical point of view the author described the various types of the cyclone dust collectors as follows.
(1) From the book of _??_ et al (1978), the characteristics of the collection efficiencies, the coefficient of the pressure drop and the main constructions of the three types of cyclones (_??_-38 and Type_??_) for the separation of sawdusts were written. The relationships between D1, ξc, Vo and 1-ηc were plotted on the figure and were described in Table.
(2) From the paper of _??_ (1963), the construction of a cyclone which had the exit nozzle (slit) surrounding on the exit pipe for ejecting the second air jet was described in the figures.
(3) From a book of _??_ et al (1977), the three types of the special constructions of the cyclone (_??_) were described in the figure and in Table.
(4) From a paper of _??_ (1958), the three dimensional rotational flows and the complicated flow circulations in the cone-cyclone which had the three inlet pipes of the rectangle sections were described in the figures. Then the collection efficiency became to going down due to the complicated flow patterns in comparison with that of the ordinary types of cyclones.
(5) The theoretical analysis for the distributions of the tangential velocities of fluids in the cone-cyclone by Bloor et al.(1973--1976) was descrined in the figure. But it was very difficult to compare the experimental results of the tangential velocities with the theoretical curves which contained many assumptions for the radia and axial velocities and the viscosity of fluid.
(6) From a book of _??_ (1980), the two systems of the aircleaner for the tractors of k-701 (_??_, Max. Power =177/ 159 kw) and k-700 (_??_, Max. Power= 221 kw) were described in the figures.
(7) From a daper of _??_ et al (1974), the special construction of a rotary flow dust collector was described in the figure.
