PERFORMANCE OF WDT FUGAL AT MARIAN MILL

WDT ENGINEERS INSTALLED an experimental low speed continuous centrifugal for processing high grade massecuites in 2003. The fugal has undergone numerous modifications to improve performance. Trials in 2011 established that the fugal is able to produce Brand 1 quality sugar at 50 t/h and 35 t/h for A and B massecuites respectively. This paper gives a brief description of the installation at Marian Mill and details the results of several investigations on the fugal. Results of purity rise, massecuite rate and sugar quality are presented as well as visual assessment of product sugar. Some minor changes to operation are planned which are expected to increase the throughput rate of the fugal to 60 t/h for A massecuite and 40 t/h for B massecuite. Purity rise is expected to be consistently below two units.
