Identify the installation by series, diameter, EGL, drive and drawings, then confirm liners, end components, discharge parts, girth gears, pinions, main bearings, drive components and ball mill relining equipment for quotation.
This page supports spare-part identification and supply for Metso ball mills; it does not replace the manufacturer's equipment manual. Select™ is a pre-engineered horizontal mill series, while Premier™ mills are configured for individual projects. Before manufacturing liners, drive parts or load-bearing components, verify the complete model, nameplate / serial number, shell diameter, EGL, drive arrangement, feed and discharge ends, drawing revision, used-part photographs and actual interfaces.
Only the published series and key dimensions needed for spare-part identification are listed. Current Metso Select™ information covers 41 pre-engineered ball mill models and their overall ranges. Dimensions, power ratings and model details not assigned to individual models in the current public information are not presented as fixed models. Premier™ configurations require confirmation from project records.
| Equipment series | Standard models / key dimensions | Key spare-part identification checks | Product status |
|---|---|---|---|
| Metso Select™ Ball Mills | 41 pre-engineered models; diameter 0.60–6.00 m; EGL 0.90–12.00 m; power 2.2–7,800 kW | Check the nameplate model, diameter, EGL, actual roller / gear drive arrangement, feed and discharge ends, liner layout and OEM drawings | Current published product range |
| Metso Premier™ project-specific ball mills | Project-specific horizontal ball mills; the current public manufacturer page does not provide a universal standard model table for direct spare-part replacement | Establish correspondence using the project data sheet, nameplate, serial number, general arrangement, drive layout, liner drawings and used-part interfaces | Current project-specific solutions |

Ball mill wear parts are grouped by shell, feed end, discharge end and material flow passages. This page provides a starting point for location and performance screening. Materials, geometry, hole patterns, thickness, weight, heat treatment and service life must be checked against ore, grinding media, particle size, wear records and drawings.
Shell Liners & Lifter Bars
Installed on the shell's inner wall, these parts protect the shell and establish the lifting and falling trajectory of the grinding media. Check shell diameter, EGL, individual liner profile, lifter height, layout, hole pattern, fastening method, wear direction and adjacent-part interfaces.
Feed-End Liners & Head Protection
Located on the feed head, feed opening and adjoining shell-liner area, these parts withstand falling material, grinding media and slurry impact. Check the feed end, head design, inner and outer liner rings, opening profile, hole pattern, fastening and feed-chute interface.
View the common part page →Discharge Grates & Pulp Lifters
For grate-discharge ball mills or mills with the corresponding discharge arrangement. Verify the discharge type, end location, openings / flow passages, lifter direction, inner and outer rings, hole pattern, discharge arrangement and trunnion interface. Do not apply this combination to an overflow configuration.
View the common part page →This section covers girth gears and pinions, mill heads and trunnions, main bearings / bearing shells / housings, main motors / gearboxes / couplings, feed chutes and discharge trommels. Confirm each against the installed ball mill configuration and drawings; do not infer it from a wear-part name or generic model.
Girth Gear, Pinion & Gear Drive
For gear-driven installations. Confirm that the mill actually uses this drive arrangement, then check module, tooth count, pressure angle, face width, helix direction, segmentation, shaft bore, center distance, tooth surface treatment, lubrication and connections.
View the common part page →Mill Heads, Trunnions & Main Bearing Housings
These large load-bearing components connect the heads, shell, feed / discharge passages and main bearings. Check the feed or discharge end, journal, flanges, hole pattern, bearing design, fixed / floating end, oil passages, seals, machining datums and nondestructive testing requirements.
View the common part page →Motor, Gearbox, Couplings & Auxiliary Drive
Confirm the main motor, gearbox, high- and low-speed couplings, brake, inching drive and lubrication interfaces against the installed drive arrangement. Provide power, speed, ratio, torque, mounting, shaft ends, coupling type, controls and rotation direction.
View the common part page →Feed Chute, Trommel & Critical Interfaces
Current Metso Select™ information lists feed chute / spout and discharge trommel options. For quotation, verify whether they are fitted, then check interface flanges, seals, liners, supports, screening media, maintenance clearance and connections to adjacent equipment.
View the common spare-parts catalogue →Provide the Select or Premier series, complete nameplate / serial number, diameter, EGL, drive type, feed and discharge ends, drawings, used-part photographs, interface dimensions, material and actual operating conditions.
No. They only narrow identification. Liners require confirmation of position, layout, hole pattern and fastening. Drive and load-bearing parts also require checks of the drive, tooth geometry, shaft ends, bearing design, drawing revision and physical interfaces.
No. Metso identifies it for smaller SAG and ball mills. Suitability still depends on mill openings, dimensions, liners, lifting arrangements, deck, site layout and safety conditions.
Provide the complete nameplate, serial number, diameter, EGL, drive, feed and discharge ends, liner / spare-part position, drawings, used-part photographs, material and operating conditions. ANRANST uses these for drawing and engineering review, production at certified foundries, in-factory inspection and finished-part delivery.

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.
