Feed Throat Liners
Feed Chute / Throat Liner
These withstand direct coarse-ore impact and sliding wear. Check inlet profile, flange interface, hole pattern and clearance to the feed chute.

FLS SAG/AG installation identification
This FLS family is identified by project dimensions and configuration. Only official published ranges are listed; independent model codes are not invented.
| Series / configuration | Officially published dimensions or parameters | Key spare identification checks |
|---|---|---|
| Fuller-Traylor SAG Mill | Diameter 4.3–12.2 m; installed power up to 28,000 kW; ball charge 6–15% | Diameter × effective length, serial number, feed/discharge direction, liner segmentation and drive configuration |
| Fuller-Traylor AG Mill | Within the same published 4.3–12.2 m diameter range; autogenous grinding uses ore without steel ball media | Diameter × effective length, serial number, discharge method, liner system and support structure |
| Support arrangement | Trunnion-supported or shell-supported | General arrangement drawing, foundation interfaces, bearing type and journal or shell load-bearing structure |
| Drive type | High-speed geared, low-speed direct or gearless drives; gear-driven arrangements may use single or dual pinions, with published single-pinion references up to 10,000 kW | Girth gear, pinion, drive shaft, coupling, reducer or ring motor interfaces |
| Discharge configuration | Trommel or vibrating screen; published FLS AG/SAG trommel diameters reach 6.0 m | Discharge grates, pulp lifters, discharge cone, trommel interfaces and rotation direction |

Wear Parts
Feed end, shell and discharge end wear systems
Impact, abrasion and slurry erosion differ between positions within the same mill. Cards identify positions and candidate materials; confirm final requirements against installation drawings, drawing, hole patterns and operating conditions.
02
Inner Feed Head Liners
Inner Feed Head Liner
These protect the inside of the feed head against combined ore impact, abrasion and slurry erosion. Confirm segment boundaries and thickness against installation drawings.

03
Outer Feed Head Liners
Outer Feed Head Liner
These cover high-impact areas around the outer feed head ring. Check installation relationships together with inner head liners, shell liners and fasteners.

04
Shell Liners and Lifters
Shell Liner & Lifter Bar
These control the charge lifting trajectory and protect the shell. Profiles, lift height, segmentation and bolt hole patterns directly affect grinding and liner life.

05
Discharge Grate
Discharge Grate
Grates control discharge passages and withstand slurry erosion, ore impact and blockage loads. Opening shape, open area and rear support must be compatible.
View Part Details →
06
Intermediate Discharge-End Liners
Discharge Middle Liner
These connect the grate and end liner systems. Check radial position, adjacent overlaps, fastening direction and wear allowance.
View Part Details →
07
Outer Pulp Lifters
Outer Pulp Lifter
These direct slurry passing through the grates toward the discharge passage. Flow cross-section, rotation direction and adjacent grate positions must match the installation.
View Part Details →
08
Inner Pulp Lifters
Inner Pulp Lifter
Located inside the discharge system, these transport slurry and control backflow. Check flow direction, blade height and assembly sequence.
View Part Details →
09
Discharge Cones
Discharge Cone
These connect pulp lifters to the discharge trunnion passage. Check cone profile, segmentation, flange hole patterns and discharge direction.

10
Filler Rings and Sealing Liners
Filler Ring & Sealing Liner
These fill gaps, cushion and seal within the liner system. Match compression, groove profile, fluid and adjacent metal part dimensions.

Gear pairs, trunnions, bearings and heavy-duty drive assemblies
Gear drives, trunnion support and shell support require different spares. Establish individual matches after receiving the full installed model, serial number, general arrangement drawing and OEM or drawing.
01
Drive Pinion
Pinion
For gear-driven configurations. Check tooth count, module, pressure angle, helix angle, journals, tooth accuracy and heat treatment together with the girth gear.
View Part Details →
02
Girth Gear
Girth Gear / Ring Gear
For single- or dual-pinion drives. Confirm split joints, tooth geometry, runout, mating marks and installation datums as a system.
View Part Details →
03
Mill Trunnions
Mill Trunnion
These carry loads and provide feed/discharge interfaces on trunnion-supported mills. Check flanges, journals, bores, fillets, concentricity and bearing fits against the general arrangement drawing.
View Part Details →
04
Trunnion Bearing Liners and Main Bearings
Trunnion Bearing & Bearing Bush
For sliding bearing configurations. Check journal diameter, bearing surface radius, oil grooves, temperature measurement holes, and Babbitt layers or copper alloy structure.

05
Heavy-Duty Drive Assemblies
Heavy-Duty Drive Components
These include drive shafts, couplings, reducer interfaces, shaft sleeves and fasteners. Identify them separately for high-speed geared, low-speed direct or gearless drives.

06
Liner Fastening and Sealing Assemblies
Liner Fastener & Seal Set
These include liner bolts, nuts, washers, gaskets and associated clamping parts. Confirm bolt grade, length, head type and hole positions together with the liners.

Frequently asked questions
How is an installed FLS SAG/AG mill identified?
Use the equipment nameplate, serial number, mill diameter and effective length, support arrangement, drive configuration and general arrangement drawing together. Appearance alone is insufficient.
Can I enquire with only a drawing or used-part photos?
Start by submitting the drawing, matching equipment model, installation position, used-part photos and critical dimensions. These support checks against drawing, the BOM and installation drawings.
Must every liner in a mill use the same material?
Not necessarily. Feed end, shell, discharge end and pulp discharge systems operate under different conditions. Confirm material and structure separately by position, failure mode and original design.
