ABSTRACT:
An automatic rate matching system is provided such that the delivery of bulk material is matched with the quantity of bulk material required by a process. An optical probe is used which determines the depth of material delivered into a hopper, prior to its retrieval for use in the process. The probe and associated electronic components output a signal to a CPU which then varies the speed of a belt conveyor based upon the depth of material. As the material depth decreases, belt speed is increased. Conversely, as material depth increases, belt speed is decreased. Therefore, the delivery rate of bulk material is matched to the quantity required in a process by varying the speed of the conveyor belt, based upon the depth of material in the hopper.
