BJD Crushers has supplied six BJD Hammermill units for pulverising coal at the Worsley Alumina refinery co-generation power plant in Western Australia.
BJD Crushers supplied the Hammermill crushers through Brightwater, as part of a $500m AE&E Australia contract to build the co-generation power plant near Collie.
The Worsley Alumina refinery uses the Bayer Process to extract metallurgical grade alumina which is used as a feedstock for aluminium smelting.
The powerhouse project at the refinery comprises two 340t per hour Circulating Fluidised Bed boiler units that will primarily burn coal, but will also be able to burn up to 30% waste wood product.
The BJD Hammermills supplied are 24x20 machines and, installed in two banks of three, will provide ‘round-the-clock' crushing of coal to feed each of the two boilers.
The Hammermill crushers are designed for a throughput of more than 27t per hour. It will crush 50mm coal chunks into products of 8mm.
