  • Grinding Mill Liners - Mineral Processing Metallurgy

    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 the ...

  • Grate-Pulp Lifter Interaction in SAG/AG Mills - AusIMM

    It is based on: an appreciation of the process interaction between grates and pulp lifters, an interpretation of mill charge structure as it relates to discharge through grates, and an analysis of pulp and solids flow in pulp lifter channels. This approach can be used to improve the overall discharge effectiveness of AG and SAG mills.

    Liners prime duty is to protect mill shell; they also transmit energy to the mill load and lift the grinding media up. Thus, they have a key role in tumbling mills performance (Parks and Kjos, 1996). Mill shell liners have lifters with various profiles resulting in different effects on the grinding mechanism.

    Mill Lifters. The number of lifters generally can be determined by the rule-of-thumb: Number of Lifters = 3nD for double wave liners = 6.6D for single wave liners where D is the mill diameter (m). Double wave liners are more suitable for ball sizes less than 60 mm. Otherwise, single wave is preferred.
