Physics-inspired AI-based model for cold crushing strength of an iron
The cold crushing strength (CCS) of iron ore pellets produced in a straight grate indurating machine is critical to their quality and performance. This study explored two modelling approaches to accurately predict CCS: an artificial neural network (ANN) model and a physics-informed hybrid model. The ANN model was designed to predict CCS ...
