Understanding the SAG Mill in Copper Ore Mining Process
A SAG mill, or semi-autogenous grinding mill, is a type of machine used in mining and mineral processing operations. It uses the crushing and grinding action of rocks to reduce materials such as copper ore into smaller pieces for further processing. Unlike traditional mills that rely on steel balls or other media to break down materials, SAG ...

Product datasheet Upgrade your SAG mill feed chute seal
your SAG mill performs. A relatively minor wear part, the feed chute seal affects performance, lifecycle and safety with your SAG mill – and the stakes are high should it happen to fail. One of the main issues with poor sealing between the inlet chute and mill is the failure to retain water inside, creating seepage and loss of process water.
