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.

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…
