Revamped trommel increasing mineral processing efficiency

IN 2011, building contractor Abigroup approached SEE Civil to create a large capacity, mobile mineral separation plant.

The plant was required to receive dump trucks with loads of up to 100t; produce at least 1200t per hour of process material; and output 3.8 million tonnes in total material within a eight month timeframe.

SEE Civil owner and director Brian Turner responded by creating one of the world’s largest mobile trommels. “It was designed to process 1200t per hour,
but we have achieved output of up to 2000t an hour, which is remarkable,” Mr Turner said. The trommel has since been modified and upgraded to further increase efficiency. The original trommel was powered by a diesel driven hydraulic system; this was upgraded to an electric driven hydraulic system, enabling the plant to run on mains or generator power.

SEE Civil also constructed an oversize rock conveyor for the trommel, enabling large rocks to be processed down to between 2t and 4t, and conveyed into a jaw or cone crusher.

The conveyor ensures more a refined level of material processing within significantly accelerated time frames.

For the dust suppression foaming unit, the company also added high pressure and high volume water pumps and a screw compressor to the original design. The 500 rock conveyor was modified to SEE’s own design, to convey larger rocks; and the loading ramp was tailored to handle 777 dump trucks (about 90t payload) within the loading bay.

SEE Civil is proud to have the only mobile trommel of its size and capability in Australia, and is ready to deploy it.
