Details of the complete SAG Mill package. The SAG Mill has a mill diameter of 24 feet and an Effective Grinding Length ("EGL) of 18.5 feet and a structural charge mass of 315 metric tonnes. The structural design ball charge is 11% with a structural design load volume of 35%. Specific gravity of the material is 2.55.
The product from the SAG mill is further reduced in size using pebble crushers and ball mills. Hence, typical gold or copper ore requires between 2.0 and 7.5 kWh per ton of energy to reduce the particle size. Considering a typical mining operation processes 10,000 to 100,000 tons per day the energy expenditure in grinding is 50 percent of the ...

January 2007, two complete grinding circuit surveys were performed followed by a SAG mill crash stop and grind-out. After stopping the mill, a SAG mill feed sample was also collected from Conveyor 1.
SAG Mill Liners include: feed head & discharge end as well as grates (both outer, middle and inner), pulp lifters (dischargers) shell lifter bars and plates.
operation of SAG mills. SAG mills are currently the technology of choice in hard rock milling operations for reducing primary-crushed ore to ball mill feed. In recent years, the trend has been towards larger-sized SAG mills with diameters of 10.4 m (34 ft) and above, with the largest being 12.2 m (40 ft) in
There is no best sag mill liner material. Different working conditionals need different material to suit.The selection of the material of construction is a function of the application, abrasive of ore, size of mill, corrosion environment, size of balls, mill speed, etc. liner design and material of construction are integral and cannot be chosen in isolation.
Based on experience, mill-liner designs have moved toward more open-shell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebble-crushing circuit utilization and SAG mill capacity. As …
