SAG Mill End Liners Structural And Material Optimization

However, from the actual operation of the SAG mill, the design of the slurry lifter at the discharge end and the grid plate has a greater impact on the processing capacity of the mill. The increase of mill size increases the load of discharge end liner, and the discharge system should be able to handle a large number of materials.

SAG Mill Components

Once the basic operating conditions have been defined for the mill designer then, and only then, can he begin taking into account shell and head stresses and trunnion bearing sizes required to carry the load and to give the required openings for feeding and discharging the mills. Mill heads are key structural components of any grinding mill. They must carry the load of the shell assembly

Optimizing your SAG mill operation International Mining

The optimal performance of AG/SAG mills is the key to successful plant operation. All AG/SAG mills using radial or curved pulp lifters suffer from inherent material transport problems such as slurry and pebble pooling, which decrease throughput and increase energy consumption. The TPL completely eliminates slurry pooling and pebble pooling
