WEBThe ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol ...
WEBJun 6, 2016 · Based on experience, millliner designs have moved toward more openshell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebblecrushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of :1 and :1.
WEBJan 1, 2021 · Measuring filling is also necessary to estimate the composition of the load for mill modelling: rock and slurry for AG mills; rock, balls and slurry for SAG mills; or balls and slurry for ball mills. In the case of SAG mills, this requires two separate filling measurements: one for a crashstop and one following a complete grindout to quantify ...
