Item Open area and screen resistance measurements on fugal screens(BSES, 1988) Noble, AGTo 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.Item Factory scale trials with laser produced stainless steel screens : Bingera mill 1987 season(BSES, 1987) Noble, AGThe main objective in the tests carried out at Bingera was to compare the performance of two adjacent, similar, BMA K1000 centrifugals, one of which was fitted with a new set of standard Cr-Ni screens, and the other with a set of laser cut screens manufactured by CSIRO. Initially, the screens in this latter machine comprised six stainless steel segments and two segments produced from commercially pure titanium. However, the two titanium segments tore along the trailing edges several days after installation, and were subsequently replaced with stainless steel segments.Item Evaluation of laser produced stainless steel screens(BSES, 1987) Noble, AGIn an effort to develop a more acceptable alternative to the chrome-nickel screens presently in use, BSES approached the CSIRO Division of Manufacturing Technology in Sydney towards the end of 1985 to ascertain the feasibility of manufacturing fugal screens from stainless steel by some method other than the present electrodeposition technique. The eventual outcome of these preliminary discussions was that two screens (one slotted, and the other with round holes) were produced from 300 um thick stainless steel 302 sheeting using a method involving laser technology. The specifications for these two screens, together with that for the chrome-nickel screen currently used in the industry, are given in this report.Item Fibre characteristics of cane - results of measurements carried out at Bundaberg during 1986 season(BSES, 1986) Noble, AGDuring September, 1986 the decision was made to test for extreme fibre characteristics all cane varieties which are prospective Q canes, in the last season before release. The purpose of these tests was to obtain some indication which varieties were likely to cause handling problems during the milling process.Item Fibre characteristics of cane - results of measurements carried out at Bundaberg during 1987 season(BSES, 1987) Noble, AGDuring September, 1987 a total of twenty-three samples of cane were tested for extreme fibre characteristics at BSES in Bundaberg. The main purpose of this testing program, which was introduced during 1986 season, is to screen all prospective Q canes prior to their release to obtain some indication which varieties are likely to cause handling problems during the milling process.Item A wedgewire support for screens in continuous centrifugals, Bingera mill - 1987 season(BSES, 1988) Noble, AGDiscussions between Bundaberg Sugar Company, the Surescreen Group and BSES resulted in BSES sponsoring the installation of a wedgewire backing screen in a K1000 basket at Bingera Mill during 1987 season. This report presents the results of trials carried out to evaluate the performance of the machine fitted with the new wedgewire backing screen.Item Brix determination in first expressed juice by mass flow meter : SRDC final report SD97011(BSES, 1997) Mackintosh, DL; Noble, AG; Sanders, DHA series of trials have been carried out to evaluate the performance of a Micro Motion CMF025 mass flow meter in place of the standard hydrometer for brix measurement in cane pay analyses. Tests were conducted at ten sugar mills over 1994 and 1995 season. The evaluation has been painstaking and extensive in scope and has culminated in the proposal to include a Method 3A in the Laboratory Manual for Australian Sugar Mills, "Brix Determination in Juice by Vibrating Tube Density Measurement". The process has involved millers' and the growers' technical personnel.
