Reclaimer

They do this by taking reclaimed material and passing it through a conveyor system that rotates around the center of the pile to create a circle.

[1] Some Blending bed reclaimers are equipped with rakes to ensure that no material gets stuck in the machine.

In below freezing temperatures, a harder material is used to create a rake with modified edges, which allow for any ice or debris to be broken up before piling.

This chain system creates a push and pull effect that allows for any loose material to be collected and moved to the edge of the reclaimed pile.

These machines can be assembled differently based on the required reclaiming load rate and boom length.

In the event of high material flow rates, a combination of a boom and bucket wheel is used.

Modern machines are typically fully automated with their parameters (for stacking or reclaiming) remotely set.
