MILLING CONTROL & OPTIMISATION

• Integrate with visual or other rock classification systems POWER OPTIMISATION For the most productive milling operation it is often best to operate close to the maximum mill power draw The power load relationship is highly non linear and shifts around as the ore and steel load/liner changes Traditional control and modeling techniques can therefore not be used Mintek has developed a Po
