The first major commissioning failure on the SAG mill occurred during installation when the mill was inched without adequate lubricant flow, resulting in the wiping of the feed end trunnion bearing. The armature, weighing 19 tonnes, together with the top half magnet frame, were trucked two thousand kilometers to Brisbane for rewinding and repairs.Mechanical installation of a 28′ x 15,5′ SAG mill including. lubrication and cooling system. mill wear liner. commissioning assistance. surveying after trail run.

A proper seal makes all the difference in the way your SAG mill performs. Even though it is a relatively minor wear part, the feed chute seal affects performance, lifecycle and safety in the SAG mill – and a failure can be disastrous in more ways than just time and money.Therefore the SAG mill speed could not be controlled using the microphone based signal and instead was manually controlled/set by the control room operator. Thus operation/speed of the mill could and would change significantly based on a particular operator running the mill and their overall level of mill operation experience and skill.Read More
