Blasting design for increased SAG mill productivity ...

01-11-1993  SAG mill throughput is often a bottleneck to increasing plant productivity. Improved size distribution control in the mill feed can be used to increase mill production. This can be accomplished by controlling blast fragmentation as a function of energy input and rock characteristics.

SAG Mill Optimization using Model Predictive Control

For SAG mill control, expert systems are often used as they are able to detect the rapid increase in mill weight and anticipate an imminent overload using combinations of rules. However they often reduce the feed rate more than necessary in some situations, and require time to return the feed rate to maximum

SAG Mill Grinding Circuit Design - 911metallurgist

However, open circuiting the SAG mill by feeding crushed pebbles directly to a ball-mill circuit is often considered as a technique to increase SAG throughput. An option to do both can allow balancing the primary and secondary milling sections by having the ability to return crushed pebbles to SAG feed as per a conventional flowsheet, or to the SAG discharge.

Gearless mill drive (GMD) and digital services for Kinross ...

Phase One significantly expanded production capacity and is also expected to reduce operating costs. On 1 August 2018, Kinross announced that construction was complete and that first ore had gone through the semi-autogenous grinding (SAG) mill. Since then, the mill throughput increased from 8000 tpd to 12 000 tpd, representing a 50% increase.

level dropped the feed size to the sag mill became coarser and as a result the sag mill specific energy increased. The increase in feed coarseness was caused by the well-known phenomenon where bigger rocks preferentially gravitate to the outside of the stockpile. As the stockpile draws down these outer rocks are then progressively drawn
