Open area and screen resistance measurements on fugal screens
Abstract
To determine whether the decrease in fugal capacity was due to the working screen or the wedgewire backing supporting it, a series of measurements were carried out on test specimens cut from the top, middle and bottom of segments of chrome-nickel working screens removed from the two trial machines. One of these had been fitted with a wedgewire backing and the other with conventional woven mesh backing. These measurements, which were carried out by the author at the Chemical Engineering Department of the University of Queensland, included the following: Slot width and open area determination; Photomicrographs of each screen section; Screen resistance of each specimen.
