The control of production green sand systems in iron foundries has been improved by controlling batch-to-batch mulling energy instead of controlling batch mulling time. Before and after sand system control data from three production foundry green sand systems that have transitioned from mulling time control to mulling energy control will be presented. Unnecessary over-mulling can be eliminated increasing muller throughput. Sand properties and sand related casting scrap are not impacted. Further research topics for extending this strategy are discussed including continuous mulling.
