The optimal performance of AG/SAG mills is the key to successful plant operation All AG/SAG mills using radial or curved pulp lifters suffer from inherent material transport problems such as slurry and pebble pooling which decrease throughput and increase energy consumption

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
