Use the AG nominal diameter and project shell dimensions to identify feed, shell, head and discharge liner systems, gearing, materials and drawing references for enquiry.
Identify the installation by AG nominal diameter series and project shell dimensions, then confirm liner layout, discharge construction, drive configuration, material and drawing revision.
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.
Each position has different impact, abrasion, slurry erosion and material processing requirements. Follow the links to the relevant parts and materials.
Throat Liner
Protects the feed throat from ore impact, abrasion and slurry erosion. Check inside and outside diameters, length, flange, hole pattern, rotation direction and feed interface.
Material Selection: Assess chromium-molybdenum alloy steel, manganese steel or rubber composite construction for impact, wear, corrosion and replacement method.

Outer Feed Head Liner
Protects the outer ring and transition area of the feed head. Check segmentation, curvature, radial position, hole pattern, lifter interfaces and rotation direction.
Material Selection: Assess chromium-molybdenum alloy steel, manganese steel or metal-rubber composites for impact, wear and head stresses.

Shell Lifter Plate
Lifts ore and controls its trajectory as part of the AG mill wear system. Check layout, lifter height, profile, hole spacing, shell diameter and rotation direction.
Material Selection: Assess chromium-molybdenum alloy steel, alloyed manganese steel or metal-rubber composites for ore impact, hardness and wear zones.

Inner Head Liner
Protects the inner head ring and interfaces with the throat, grates or pulp lifters. Check radial position, curvature, segmentation, hole pattern, rotation direction and adjacent interfaces.
Material Selection: Assess chromium-molybdenum alloy steel, manganese steel or rubber composites for impact, slurry corrosion and head wear.
View Part Details →
Discharge Grate
Controls passage of slurry and correctly sized particles. Check aperture design, open area, segmentation, curvature, hole pattern, rotation direction, blockage and wear records.
Material Selection: Assess chromium-molybdenum alloy steel, manganese steel or rubber composites for impact, wear and aperture retention. Consider high-chromium cast iron only where specified by the drawing and validated for the duty.

Middle Liner
Fits in a transition zone of the head or discharge system. Check installation level, inner or outer ring, curvature, segmentation, hole pattern and relationship to adjacent pulp lifters.
Material Selection: Assess chromium-molybdenum alloy steel, manganese steel or composite construction for impact and wear at the specific position.
View Part Details →
Pulp Lifter
Directs slurry passing through the grates towards discharge. Check inner or outer ring position, vane direction, passage area, rotation direction, hole pattern and blockage records.
Material Selection: Assess chromium-molybdenum alloy steel, high-chromium cast iron, rubber or composites for slurry erosion, wear and structural stiffness.
View Part Details →
Discharge Cone
Guides slurry from the pulp lifters to the outlet. Check cone angle, inside and outside diameters, length, flange, hole pattern, rotation direction and discharge interface.
Material Selection: Assess chromium-molybdenum alloy steel, manganese steel or rubber composites for erosion, wear, corrosion and assembly method.
View Part Details →Check geared installations against the complete project configuration. Gearless drives do not use the girth gear and pinion arrangement.
Girth Gear / Ring Gear
Meshes with the pinion to transmit main drive power. Check module, tooth count, pressure angle, helix angle, split joints, mounting distance and contact pattern.
Material Selection: Confirm cast steel or forged transmission alloy steel, heat treatment, machining accuracy, NDT and matched-pair inspection against the original design.
View Part Details →
Pinion
Meshes with the girth gear to transmit motor and gearbox output. Check module, tooth count, pressure angle, helix direction, shaft interfaces, backlash and contact pattern.
Material Selection: Confirm forged transmission alloy steel and carburizing or quench-and-temper treatment for torque, tooth surface hardness, core toughness and fatigue.
View Part Details →Provide CITIC AG installed part numbers, general arrangements, liner layouts or part drawings to confirm the model, position and drawing revision.
Selection Guidelines: Check OEM drawing numbers and third-party references separately against the model, shell dimensions, installation position and drawing revision.
No. A diameter series may include different project lengths, discharge arrangements, liner layouts and drive types. Check project documents, nameplates and general arrangement drawings.
No. Even with similar shell diameters, confirm mill type, length, layout, profile, hole pattern, lifter height, rotation direction, material and drawing revision.
