Recent high performance technologies of dry and wet type particle separation process are explained. For the dry-cyclone, the use of apex cone in the inlet of dust box is effective to improve particle separation efficiency. Because the upward fluid velocity decreases by use of the apex cone, then the number of escaping particles decreases in this case.
The optimum cone angle of the apex cone is detected. The use of the additional air jet flow near the upper plate and inlet guide plate are also effective to improve particle separation efficiency. For the wet type particle classification, the use of electro potential and gravity force on the particles is effective to realize sub-micron particle classification.
