How To Understand Hopper Purposes and Functions

Hoppers may also be used as an interface between batch and continuous material flow. A clamshell ship unloader removes coal in batches, one clamshell load at a time. The material is deposited into the hopper, which accumulates the material and continuously feeds it onto the dock conveyor. Here is an example of a rotary railcar dumper.
