As IM October goes to press, with a feature on comminution, there is news that BJD Crushers has supplied six BJD Hammermills to pulverise coal at a new co-generation power plant being built in Western Australia. The crushers are part of a $500 million contract for the plant, which will be built at the Worsley Alumina refinery, near Collie. The units are 24 x 20 machines and, installed in two banks of three, will provide ‘round-the-clock’ size reduction of coal to feed each of the two boilers. Designed for a throughput of more than 27 t/h, they will produce a minus 8 mm product from a feed of up to 50 mm. The powerhouse project at the refinery comprises two 340 t/h Circulating Fluidised Bed boiler units that will primarily burn coal, but will also be able to burn up to 30% waste wood product. (more…)
