Ready for action — In this picture we can see the inbound conveyor coming from the outside. We also see the rotating conveyor that unloads it directly into each bin and the catwalks to get back and forth. Under the conveyors are the bins and the front-end loader used to get the material out of the bins. Illustrated here is one bin that has the door open and obviously is being unloaded. The bin on the left is now full, the door is shut, but it can be unloaded by extracting the material from under the door until such time as the bin is unloaded and the door will be raised.
