In-Pit Sizing & Conveying Systems

For the ultimate in cost savings, environmental mining and portability, fully mobile Sizer units enable the use of efficient conveyor haulage directly from the mine face. They move frequently to work directly with the excavator, whilst sizing and delivering conveyable material onto the conveyor haulage system, eliminating trucks and their associated costs, safety risks and environmental impact.

MMD have been producing semi-mobile IPSC units since the early 1980’s. Generally fed by a small fleet of trucks transporting material short distances from the mine face. The Sizer™ unit reduces material in preparation for efficient conveyor haulage out of the mine. As the mining face progresses these units are relocated occasionally to minimise the truck haulage distance.

The MMD Atlas Transporter is the latest technology from MMD, enabling heavy semi-mobile structures to be relocated in a safe and controlled manner. A single transporter can serve many units and structures around the mine. A range of MMD transporters are available from 200T to 750T carrying capacities.

With almost 40 years’ experience of innovating reliable material processing equipment, MMD has developed a mobile feeder solution that overcomes the inherent problem of intermittent loading typically seen in truck and shovel operations. Accepting direct loads from excavators, screens or Mobile Sizing equipment, the Fully Mobile Surge Loader stockpiles material and delivers a regulated flow to the truck fleet. This increases truck and shovel utilization and provides a system capacity improvement of up to 25%.
