Identify wear parts and spares by installed dimensions, support and drive configuration, then review part positions, materials, drawing numbers and enquiry requirements on one page.
The current published Fuller-Traylor SAG/AG mill range has diameters of 4.3–12.2 m and installed power up to 28,000 kW. Spare identification also requires effective length, serial number, general arrangement drawing, support and drive configuration.
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 مطحنة SAG | 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 |
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 numbers, hole patterns and operating conditions.
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.
Material Selection:Chromium-molybdenum alloy steel; steel-rubber composite designs may be assessed after confirmation against installation drawings.

حلقات التعبئة & Sealing Liner
These fill gaps, cushion and seal within the liner system. Match compression, groove profile, fluid and adjacent metal part dimensions.
Material Selection:Wear-resistant rubber or polyurethane systems; confirm hardness, rebound and fluid resistance against operating conditions.
View Part التفاصيل →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 third-party drawing number.
ترس صغير
For gear-driven configurations. Check tooth count, module, pressure angle, helix angle, journals, tooth accuracy and heat treatment together with the girth gear.
Material Selection:Forged transmission alloy steel; confirm grade, hardened layer and tooth requirements against original drawings and acceptance standards.

Submit Drawings and Numbers →Unverified numbers are not published. Submit FLS, Fuller-Traylor or third-party drawing numbers with equipment model, serial number, installation position, drawing revision and critical dimensions. Verified matches are recorded on the relevant part page.
Use the equipment nameplate, serial number, mill diameter and effective length, support arrangement, drive configuration and general arrangement drawing together. Appearance alone is insufficient.
Start by submitting the third-party drawing number, matching equipment model, installation position, used-part photos and critical dimensions. These support checks against OEM drawing numbers, the BOM and installation drawings.
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.
Provide diameter × effective length, support and drive arrangements, serial number, installation position, OEM/third-party drawing numbers, used-part photos, drawings and operating conditions. We use these to identify parts, assess materials, match manufacturing requirements, control quality and deliver finished components.
