Stacking method
In the longitudinal BE store the stacking method is to stack a large number of layers on top of each other in the longitudinal direction of the pile.
The BE store has normally two Delivery Bridges for stacking, one at either end of the store.
Windrow
With the Windrow method material is deposited from a number of positions across the full width of the pile.
The method prevents segregation and ensures more even distribution of fine and coarse particles across the pile.
The Windrow method is preferred in cases where the reclaimer is only operating in one part of the pile cross section at a time.
Reclaiming methods
On/Off mode
Reclaiming capacity is higher than the mill requirement and the reclaimer therefore operates in an On/Off mode, controlled by maximum/minimum level indicators in the feed bin. On leaving the bin the material is proportioned and fed to the mill by weigh feeders.
Direct mode
If the material is difficult to handle it may be an advantage to avoid the intermediate bin between the reclaimer and the mill. This is possible in cases where material from one (or more) store(s) is to be fed to a single mill.
Reclaiming capacity will always match the mill requirement and the reclaimer will operate continuously.
The reclaimer in combination with the transporting belt conveyors acts as a weigh feeder for the reclaimed material.
Special designs
In case of special requirements due to specific material properties or limited space FLSmidth can offer a vide range of special designs.
