Antofagasta receives approval for $ expansion of . Throughput at the plant will be increased from the current capacity of 175 000 tonnes of ore per day to an average of 190 000 tonnes of ore per day The plant expansion includes an additional SAG mill ball mill and the corresponding flotation circuit with 24 …The SGI equation uses a transfer size between a SAG and ball mill; it is proposed that a synthetic transfer size of 2100 µm be used to model single-stage SAG mills. 5.9ˇ √˙˝ ˛ . ˚ 0.96 0.985˜ !"# ˝ $ ˝ √˙˝ %&'() (2) where: SGI is the SAG Grindability Index, minutes, P80 is the SAG hydrocyclone overflow 80% passing size, µm


The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...FAG TO SAG CONVERSION PROJECT It was the combination of increased throughput targets associated with anticipated harder ore with finer grind requirements, that finally pushed the decision to convert the primary mill to semi autogenous grinding (SAG) in October 2005. The circuit delivered by the conversion project is

The voltage in stator windings forms the current and magnetic flux. The di-rection of this flux can be determined using the right hand rule from the stator current.


SAG Mill Design and Specification . The Kidston plant was designed to process 7500 tpd fresh ore of average hardness; but to optimise profit during the first two years of operation when softer oxide ore will be treated, the process equipment was sized to handle a throughput of up to 14 000 tpd. Some of the equipment, therefore, will become ...how to convert sag mill to ball mill. 2006).
