SAG Mill

2005-06-01Having been in a few process plants with SAG mills they are inefficient- as low as 1% - since power costs are becoming a big issue there is lots of research being done ( try googling under SAG Mill efficiency) -technically I wouldn't consider them a 'crusher'- they are grinding mills and some mill people might take offence- note that SAG mills are high compared to length-this is so the

SAG Mill Liner Design

No discussion of SAG milling would be complete without mention of relining Unlike a concentrator with multiple grinding lines conducting SAG mill maintenance shuts down an entire concentrator so there is a tremendous focus on minimizing required maintenance time the reline timeline often represents the critical path of a shutdown (but typically does not dominate a shutdown in terms of
