Identify the installation by Select™ / Premier™ series, diameter, EGL, drive, feed and discharge ends, and drawings. Then confirm liners, gear drives, trunnion bearings and manufacturer-documented SAG relining tools.
This page supports identification and supply of Metso SAG mill spares. Select™ is a pre-engineered horizontal mill range; Premier™ is configured for individual projects. Before manufacturing liners, trunnions, bearings, gears or drive parts, check the complete model, nameplate or serial number, diameter, EGL, drive, feed and discharge ends, liner arrangement, drawing revision, used-part photographs and actual interfaces together.
The table gives the standard model count and key ranges needed to identify spare parts. Metso's 2025 Select™ brochure lists 31 pre-engineered SAG models and overall dimensional ranges. Dimensions, power ratings and model details not publicly matched to individual machines are not presented as verified fixed models. Identify Premier™ installations from project records.
| Equipment series | Standard models / key dimensions | Spare-part identification checks | Product status |
|---|---|---|---|
| Metso Select™ SAG Mills | 31 pre-engineered models; diameter 3.80–9.00 m; EGL 1.90–4.50 m; power 400–7,800 kW | Check nameplate model, diameter, EGL, gear drive or actual drive arrangement, feed and discharge ends, liner layout, trunnion bearings and OEM drawings | Current published product range |
| Metso Premier™ SAG project solutions | Project-engineered horizontal SAG mills; the current manufacturer page does not provide a single standard model table for direct spare-part replacement | Establish the match from project data sheets, nameplate, serial number, general arrangement, drive layout, liner drawings and used-part interfaces | Current project-engineered solution |

SAG wear parts are grouped by systems with similar material and manufacturing requirements. Once drawing are confirmed, this equipment page can link known numbers to part positions, applicable models, performance requirements and materials.
Feed Throat, Head Liners & Transition Rings
Covers the feed throat, inner and outer head rings, transition rings and adjacent shell liners. Check the feed end, inlet profile, head segmentation, holes, bolts, retention, material drop direction, adjoining liner interfaces and wear records.
Shell Liners, Lifters & Manhole System
Protect the shell, lift ore and steel balls, and control their trajectory. Check diameter, EGL, layout, lift height, individual profiles, wear direction, manhole liners, holes, retention, maintenance access and set quantities.
Discharge Grates, Pulp Lifters & Discharge Cone
For SAG mills with grate discharge, covering grates, inner and outer pulp lifters, the discharge cone and filler rings. Check the end, openings and passages, rotation direction, channel segmentation, inner and outer rings, discharge method, trunnion interfaces and anti-blockage requirements.
General SAG spares include girth gears and pinions, trunnions and main bearings, motors, gearboxes, couplings, inching drives and critical connections. Available information supports structural identification only; fixed tooth geometry, materials, heat treatments, dimensions and OEM order numbers are not published without installation drawings.
Girth Gear, Pinion & Gear Drive
For installations that use a gear drive. Check module, tooth count, pressure and helix angles, face width, rotation direction, split construction, shaft bore, center distance, tooth-surface treatment, lubrication and the mating pinion.

Trunnion, Main Bearings, Bushings & Housings
Support the large rotating assembly and form the feed and discharge passages. Check feed or discharge end, journal, head flange, fixed or floating end, bearing type, bearing liners, oil passages, seals, housing, machining datums and nondestructive testing.
Open the Common Part Page →
Motor, Gearbox, Couplings & Inching Drive
Confirm the motor, gearbox, high- and low-speed couplings, torque limitation, braking, inching drive, lubrication and controls against the installed drive arrangement. Check power, speed, ratio, torque, shaft ends, mounting, controls and rotation direction together.
Open the Common Part Page →Feed Chute, Trommel & Critical Interfaces
The published Metso Select™ scope includes feed chute or spout and discharge trommel options. Confirm whether each is installed, then check flanges, seals, liners, supports, screen media, maintenance access and adjacent equipment.
Open the Common Spare-Parts Catalogue →Provide the Select or Premier series, complete nameplate or serial number, diameter, EGL, drive, feed and discharge ends, discharge structure, drawings, used-part photographs, interface dimensions, materials and actual operating conditions.
No. They only narrow identification. Liners require position, layout, holes and retention checks; grate-discharge parts require flow passages and rotation direction; drive and load-bearing parts also require tooth geometry, shaft ends, bearing structure, drawing revision and actual interfaces.
No. Metso identifies it for smaller SAG and ball mills. Actual suitability depends on the mill opening, dimensions, liners, lifting requirements, deck, site layout and safety conditions.

ANRANST provides customers worldwide with engineering assessment, production at certified foundries to the customer technical requirements, quality control and finished-part delivery for custom wear parts and industrial spares, with scope to support other custom industrial parts.
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Material grades and heat-treatment processes are specified order by order, stated in the technical agreement and tracked through production.
Drawing confirmation, material and process control, production tracking, inspection and acceptance coordination.
We coordinate manufacturing, quality confirmation, packaging and delivery of complete finished parts in a workable, closed-loop supply process.
Provide the existing model, drawings, drawing, materials or operating conditions so we can identify the appropriate technical review and supply route.
