Comminution circuit bottlenecks – How to increase plant ...

Mar 25, 2019 · SAG mills. Replacements are seldom done to SAG mills due to cost and also the constraints of other circuit equipment. Instead, often additional production lines are added. Also, if the bottleneck is the SAG mill, adding a pebble crusher can provide a small production boost (typically 5 to 10%). Ball mills. For ball mills, replacement is less ...

Ball And Sag Mill Circuits - gautengcc

circuit is shown in Figure1. It is commonly referred to as a SABC circuit, for Semi-Autogenous Ball mill Crusher (SABC). This circuit shows a semi-autogenous grinding (SAG)/ball mill circuit where both grinding mills are in closed circuit, with the SAG mill closed with a crusher to control the amount of 'critical size' material in the circuit.

FREDA REBECCA SAGMILLING CIRCUIT OPTIMIZATION

increasing throughput is the single stage Semi autogenous milling (SAG milling), this is to a large extent due to major ore hardness variations and coarse feed size distribution. This work is aimed at optimizing the SAG mills feed size distribution as this is an important parameter that affects milling performance after ore competency.

Grinding Circuits - na.srk

Initially faced with a blend of primary and oxide ore, the circuit achieved in excess of 320tph until the oxide was depleted, leaving only the much harder primary feed. The 2.0MW semi-autogenous grinding (SAG) mill and 3.7MW ball mill was assisted by a 150kW pebble crusher, but the power limitation of the SAG mill resulted in a drop in throughput.

Controlling fragmentation - Orica Mining Services

SAG mills is less than 5%. To give some context, an example metal mine might spend $5.00/t of ore on electricity; an equivalent amount on grinding media in the SAG circuit alone; but only $0.30/t of broken ore on explosives at the drill and blast stage. Yet, the blasting process is a much more energy efficient method of fragmenting rock.
