Flow Rate Computation: Automatic Dumping Hoppers
A one-page application note (EAI Bulletin ALMP6369-1ob, 1963) describing the use of an EAI PC-12 Process Control Computer to compute flow rates from automatically-dumping hoppers in grinding mill operations. A simple analog circuit computes individual product rates (R = W/t) and fractional production rates, giving mill operators real-time feedback for adjusting grinding parameters. The note includes a circuit diagram for the dumped-hopper computing circuit.
