Surface Mining: Windrowing
When the cut material is deposited in windrows, it is deposited directly behind the machine without using the conveyor. This means the cutting process can be carried out separately from the loading process (onto a truck). The material does need to be reloaded using a front loader, however.
In many applications, the higher productivity of the windrowing method compared to direct loading compensates for the additional cost of reloading the material (e.g. with wheel loaders).In addition, this method does not cause any wear and tear to the conveyor belts and eliminates the cost of operating the conveyor system.
