Claim Text:
1. A system of unloading bulk material, comprising: at least one silo for receiving a bulk load discharged from a load transport device; at least one feeder to feed the load from the at least one silo to a conveyor belt; and a flow control device that regulates one or more operating parameters of the at least one feeder to make sure that an estimated calibrated flow rate corresponds to a desired flow rate; wherein the estimated calibrated flow rate is obtained based on a calibration factor calculated by comparing an estimated flow based on the one or more operating parameters of the at least one feeder with a measured flow rate measured downstream of the at least one silo; wherein the at least one feeder comprises a plurality of feeders; and wherein the estimated flow is obtained based on a current and a speed of the plurality of feeders, based on the following equation: where y=estimated flow, u
