  • CA1138397A Shell liner assembly for ore grinding mills

    Abstract The disclosure is directed to an improved liner assembly for an ore grinding mill. The liner assembly is of the segmented type, comprising a first plurality of holder segments which are mounted directly to the shell of the mill, and a second plurality of wear segments which are mounted to the shell in overlying relation to the holder segments, which are thus virtually unexposed to theSemi-autogenous grinding (SAG) mill liner design and,• to provide an economic liner wear life. Shell liner design is driven primarily by the practical operating experience with various combinations of lifter heights, spacing and angles. Changing the face angles of shell lifters alters grinding ball trajectories, and hence the point of impact within the mill

    There are basically two groups of Grinding Mill Liners. Ones with a HIGH PROFILE and those with a LOW PROFILE. The high profile liner is designed to give the media the higher lift. This type will be used in mills that are designed for primary grinding and as a result require the impact of the higher cascade. Ball mills working as the secondary portion of a grinding circuit will utilize theTECHNICAL NOTES 8 GRINDING R. P. King,1.
