Key Considerations When Selecting A Mill Lining System

Key Considerations When Selecting A Mill Lining System

Jan 27, 2020 Ball mills, conversely, contain grinding media up to 50mm in diameter, occupying between 25% - 40% of mill chamber volume. To effectively reduce material size, each type of mill needs to generate different charge load actions, or the type of motion characterised by the mill’s contents. SAG mills generate higher levels of impact reduction and ...
