Description
The latest addition to FLSmidth’s line of At-the-Face solutions, the Drive Over Dump Station (DODS) is a semi-mobile in-pit sizing station. When used with a material conveying system, the Drive Over Dump Station is located a short distance away from the face of the mine in order to give the mine flexibility with its haul truck fleet while keeping the haul distances to a minimum. The material, such as coal or overburden, is processed through the machine and sized to an acceptable size for conveying the material out of the pit. The system can be relocated as the haul distance increases.
The Drive Over Dump Station functions similar to a traditional dump station, but offers the added flexibility of mobile sizing without the need to build costly and time-consuming retaining walls. A truck approaches the DODS by way of an earthen ramp. A bridge spans from the top of the earthen ramp to the DODS. The haul truck drives across the bridge and the gates open exposing the hopper below. After the gates are in the raised position, the truck dumps its payload into the hopper. The truck then lowers its bed and pull away from the dump station using the second bridge and earthen ramp to exit the DODS.
As the truck dumps material into the hopper, the apron feeder begins conveying the material to the sizer where it is crushed to the appropriate size. After being crushed, the material is discharged onto the bench conveyor, where it is taken out of the pit.Applications
The Drive Over Dump Station is one of several At-the-Face Mining solutions developed by FLSmidth’s RAHCO Technology Center. The Drive Over Dump Station,
Dual Truck Mobile Sizer, or
Triple Track Mobile Sizer can be integrated as part of an In-pit Crushing and Conveying system that offers the flexibility of haul trucks with the low cost of mobile conveying.
