AG Nominal Diameters and Project Shell Dimensions
The model suffix identifies nominal shell diameter. Mill length, drive, discharge and liner layout vary by project.
| Model Series | Nominal Shell Diameter | Shell Length | Required Checks Before Manufacturing |
|---|---|---|---|
| AG-40 | 4,000 mm | Confirm against the mill shell length for the project | Nameplate, general arrangement, discharge and drive configuration |
| AG-50 | 5,000 mm | Confirm against the mill shell length for the project | Nameplate, general arrangement, discharge and drive configuration |
| AG-61 | 6,100 mm | Confirm against the mill shell length for the project | Nameplate, general arrangement, discharge and drive configuration |
| AG-73 | 7,300 mm | Confirm against the mill shell length for the project | Nameplate, general arrangement, discharge and drive configuration |
| AG-80 | 8,000 mm | Confirm against the mill shell length for the project | Nameplate, general arrangement, discharge and drive configuration |
| AG-92 | 9,200 mm | Confirm against the mill shell length for the project | Nameplate, general arrangement, discharge and drive configuration |
| AG-104 | 10,400 mm | Confirm against the mill shell length for the project | Nameplate, general arrangement, discharge and drive configuration |
| AG-110 | 11,000 mm | Confirm against the mill shell length for the project | Nameplate, general arrangement, discharge and drive configuration |
| AG-122 | 12,200 mm | Confirm against the mill shell length for the project | Project, nameplate, general arrangement and gearless drive configuration |
A diameter series may include different lengths, drive types and discharge arrangements. Liners and spare parts cannot be matched by diameter alone.

Frequently asked questions
Does AG-122 identify a single mill length and drive arrangement?
No. A diameter series may include different project lengths, discharge arrangements, liner layouts and drive types. Check project documents, nameplates and general arrangement drawings.
Are AG and SAG mill liners directly interchangeable?
No. Even with similar shell diameters, confirm mill type, length, layout, profile, hole pattern, lifter height, rotation direction, material and drawing revision.
How can CITIC AG parts be identified without a drawing?
Submit the nameplate, shell diameter × length, general arrangement, installation position, used part photographs, liner layout and critical dimensions to assess identification, dimensional survey and manufacturing feasibility.
