Surface Mining: Windrowing
When working in windrowing mode, the cut material is deposited directly behind the machine without using the conveyor. This makes the cutting process independent of any loading processes (onto trucks). However, the material must subsequently be re-handled by a front loader.
In many cases, the higher productivity achieved by windrowing as compared with direct loading balances out the additional costs incurred for renewed handling of the material (e.g. by wheeled loaders). Moreover, this method does not give rise to any belt wear and does not incur operating costs for the conveyor system.
