The grinding curve is the product size as a function of feedrate for a fixed feed size It is proposed that for each new milling condition in this case a change in the percentage of ball scats in a mill the peak in the grinding curve must be sought and that must be used as the comparative test condition
Milling curves as a tool for characterising SAG mill performance that the grind will follow the power curve or put architecture for a singlestage grinding mill circuit closed with a
• Uses the changes in the mill load and power to automatically detect whether the mill is overloaded or underloaded • Uses safety controllers to change the solids feed rate and feed water to prevent mill overloads • Estimates the power load curve and optimum load By optimising the mill power usage and preventing mill overloads
The performance of tumbling mills is sensitive to the volumetric mill filling which influences grinding media wear rates throughput power draw and product grind size from the circuit Each of these performance parameters peaks at different filling values In order to continuously optimize mill operation it
