Development and Implementation of the Algorithm of Power Draw Modeling for Semi-Autogenous Mills

Semi-Autogenous/Autogenous (SAG/AG) mills are used widely in iron, copper, gold and other minerals grinding. In recent decades, several mathematical models were presented by various mineral processing researchers for predicting the performance of these mills. Computer simulation using these models is one of the validated techniques for predicting of mills power draw. In this work power draw of SAG mills was simulated which is also applicable for predicting the power draw in other types of tumbling mills such as ball mills. This model is based on describing of charge motion and the position of toe and shoulder of charge in the mill and charge kinetics and potential energy. This simulator computes toe and shoulder angles of charge, power requirement for tumbling charge, no-load power, net power and total power of SAG mills.
