Model predictive control provides an additional tool to improve the control of Semi-Autogenous Grinding mills and is often able to reduce process variability 

The drive for low operating cost has seen the retention of fully autogenous circuits in some large installations, notably Olympic Dam. ISSUES IN MILL AND 

Your operation requires a Semi Autogenous Mill (SAG mill) or Autogenous Mill (AG Mill) that is flexible, durable, cost-efficient and tailored to your specific needs and use cases. That's why

Implementation of the new design in the SAG mill was carried out, resulting in increase in daily throughput from 6 to 12%. Further, the time spent in liner change was reduced by 47% given the

A SAG mill is usually employed like a primary or initially stage grinding remedy The SAG mills make use of the nominal ball charge of 6 to 15%. SAG mills could be as massive as 42" across, with as numerous like a 28 MW motor.

SAG mills are the main workhorses in the majority of comminution circuits globally. They need to be fed and kept working round the clock. But challenges can arise when capacity is not optimised causing unnecessary downtime and liner wear leading to the one sound operators do not want to hear - the sound of the mills standing still.

7 [1]. Size reduction occurs through a primary crusher followed by semi-autogenous grinding (SAG). Large rocks are screened from the overflow and are sent
