Manage your mined materials with mobile spreaders and stackers

The environmental impact of mining operations are a cause for revisiting traditional processes to find solutions that will improve their effects on the world we live in.

The purpose of the mobile spreader (MSP) and the mobile stacking conveyor is to receive overburden, tailings or other waste material from a haulage conveyor, and stack it in an orderly and efficient manner to support landscape re-cultivation (in the case of waste material), or to stack run-of-mine material for leaching.

Especially with dry tails stacking, we have recognised that this mine waste management method significantly improves environmental impact and reduces mine process water consumption. Our mobile conveying systems provide a very cost-effective, efficient and environmentally friendly method of handling these materials.

Our extensive line of mobile spreaders ranges from 30 m (100-ft) to more than 350 m (1,150-ft) in length. The FLSmidth MSP series includes compact, C-frame, and cross-pit spreaders to support a wide range applications. Rail or track-mounted tripper cars, usually part of the spreader package, are used to transfer the material from the haulage conveyor to the spreader. We tailor your MSP to suit your specific site.

The mobile stacking conveyor (MSC) is a single conveyor supported on a series of truss frames and crawler tracks. A single conveyor belt flight runs along the top chord of the trusses, along the length of the MSC. The MSC’s tracks allow for lateral or radial travel, with some flexibility for mine stacking strategies.

The mobile stacking conveyor tripper (MSCT) travels along the top chords of the mobile stacking conveyor. The tripper “trips,” or transfers, material onto the cross conveyor belt and discharges the material onto the stack. The cross conveyor is bi-directional and designed to advance-stack (where the MSC travels on top of the stack that it is creating) and/or retreat-stack (where the MSC travels in front of the stack that it is creating). The MSCT and cross conveyor are engineered to provide an adequate setback from the stack edge for advance stacking, as well as keeping the crawler track back from the advancing toe of the stack embankment during retreat stacking. The mobile spreader is used in series with the MSC to afford an added safety factor to the setback on the advance-stack, in situations where the newly stacked material may have an unstable embankment.
