Abstract
The main technical problem with Dual Cyclones with Water Injection used as classifiers in grinding circuits is that they do not allow for control and regulation of the input velocity ratio between the first and second cyclone as well as the high pressure required at the intake of the first cyclone to achieve a sound operation of the second cyclone. The disclosed invention solves the technical problem by making the feeding and discharge of both cyclones' overflows form a volute in the horizontal plane with the body of the respective cyclone and by placing, between its bottom and the expansion zone, a selectively, axially-positionable member.
