The shell liner type, rotation speed, and ball filling percent are the key factors influencing the charge behavior inside the SAG mills, and consequently, their performance. In this work, the milling operation of industrial SAG mills is investigated using the Discrete Element Method DEM. First, an industrial SAG mill with dimensions of 9.50 m 215 4.42 m that has a Smoothtype liner is simulated.
14-10-2018· SAG Mill Liner Selection to Maximise Productivity. With an increasing treatment of complex ore bodies with variable competencies, SAG mill liners and discharge systems are proving to be crucial components controlling the power draw and the resulting throughput and grinding performance.
SAG mill liner development draws primarily on practical experience from SAG milling operations supportedputer based modeling of charge motion in SAG mills and on established good design practice. Liner design needs to respond to the process aspects of mill liner action that are critical to good SAG mill performance, i.e.,
SAG Mill Liner Design Mineral Processing & Metallurgy. To a more significant degree than in other comminution devices, SAG Mill Liner Design and Configuration can have a substantial effect mill performance. In general terms, lifter spacing and angle, grate open area and aperture size, and pulp lifter design and capacity must be considered.
