PERFORMANCE OF A TANDEM OF BUNDABERG TWO-ROLL MILLS

WHEN constructed, Tableland mill was the first sugar factory built in Queensland for more than 70 years. Its first year of operation was 1998. The Tableland factory is unique in that its crushing tandem consists solely of two-roll Bundaberg High Extraction Mills (BHEMs). This paper documents the performance and operational experience of the Tableland tandem. The low final bagasse moisture and modest specific power consumption of the Tableland tandem are especially attractive when sugar cane is viewed as renewable biomass with an energy content significantly in excess of that required for the production of crystal sugar. The low final bagasse moisture achieved at Tableland contributes significantly to the efficiency of the boiler and the good overall operation of that station.
