For a bridge reclaimer, the base must be flat. The reclaim line moves along the base, parallel to the y axis, and all material above the line is reclaimed, as well as any material that rills down. Material is reclaimed in a series of arcs. Each arc is at a specified height, called a bench height. Each arc moves parallel to the y axis, and all material above the arc is reclaimed, as well as any material that rills down.
Material is reclaimed in a series of arcs.
Each arc is at a specified height, called a bench height. Each arc moves parallel to the y axis, and all material above the arc is reclaimed, as well as any material that rills down. There is a series of gates at the base of the pile at specified positions and with specified sizes. Reclaiming is done by opening one or more of these gates to allow material to flow into a tunnel below. The movement of material for tunnel reclaiming is fairly complex and is described more fully in Section 3.
