SAG Mill Liner Design - Mineral Processing Metallurgy

Semi-Autogenous Grinding (SAG) Mills. The shell liner profile possible is primarily determined by the chordal dimension. The profile must minimize packing and plate wear but give sufficient lift for proper grinding action. Liner profiles are as numerous as operations. They range from typical plate and lifters to “rail” or integral liners.
