BALL MILL LINER SYSTEM

مطحنة الكرات بطانة الأنظمة

Shell, lifter bars, head liners, discharge and trunnion protection

Liners protect the mill structure and influence the movement of balls and ore, working volume, discharge capacity and shutdown intervals. When replacing them, check every installation zone as part of one continuous system.

Shell Zone Shell liners, lifter bars and liner fasteners
End Zones Feed-end, discharge-end and trunnion liners
Discharge Zone Discharge grates, pulp lifters and discharge passages
متطلبات التحديد Model, dimensions, discharge arrangement, drawing references and operating conditions
Ball mill shell liners and lifter bars
Liner profile, spacing, worn contour and fastening method together affect grinding-media movement and liner life.
System scope

Build a complete BOM by installation zone and discharge arrangement

Ball mills with the same diameter may differ in shell length, head construction, bolt holes, lifter profiles and overflow or grate-discharge arrangements. A request stating only “ball mill liners” is insufficient.

Shell and Head قطع الغيار المستهلكة

Different positions face different impact, abrasion and structural loads

Each card links to the corresponding general part page, where equipment, position, material and drawing references can be checked.

Ball mill shell liners Shell Working Zone

بطانات الجسم

Protect the shell and define the boundary for grinding-media movement. Check curvature, thickness, hole positions, layout, profile and minimum safe thickness after wear.

Ball mill lifter bars or plates Media-Lifting Zone

Lifter Bar / Lifter Plate

Control the lifting, cataracting and cascading of balls and ore. Height, angle, spacing and worn profile must match speed, filling and target particle size.

Ball mill feed-end liners Feed End

بطانة طرف التغذية

Protect the feed head against fresh feed, grinding balls and circulating loads. Check segment geometry, centre opening, bolt holes and feeder connections.

Ball mill head liners Discharge End / Mill Head

Discharge-End / Head Liners

Protect the discharge head and connect with the discharge system. Confirm overflow or grate discharge, central construction, segmentation and clearances to adjacent parts.

Ball mill trunnion liners Feed and Discharge Trunnions

بطانة العمود المجوف

Separate ore or slurry from the trunnion body. Check inside and outside diameters, length, flanges, flow-guiding profile, fastening and sealing connections.

Grate-Discharge System

Use grates and pulp lifters only with the corresponding discharge arrangement

Overflow and grate-discharge ball mills have different discharge-end structures. Their discharge parts must not be assumed interchangeable.

Ball mill discharge grates Grate-Discharge Configuration

شبكة التفريغ

Control the passage of particles and slurry into the discharge chamber. Check slot size, open area, blockage risk, thickness and fastening against grinding-ball size and flow.

Ball mill pulp lifters Behind the شبكة التفريغ

Pulp Lifters

Guide slurry passing through the grates toward the trunnion. Check blade geometry, channel volume, rotation direction, adjacent clearances and lining construction.

Ball mill discharge-chute liners External Mill Discharge

بطانات قناة التفريغ

Protect the external discharge passage. Select materials by zone using drop height, flow direction, particle size, slurry concentration, fastening and maintenance access.

Materials and Properties

Position, energy and maintenance targets determine the material system

These are candidate material families, not fixed grades or life guarantees for every ball mill.

Cr-Mo Alloy Steel and Other Metal Liners For positions requiring structural strength, profile retention and resistance to impact and abrasion. Confirm composition, hardness and heat treatment against operating conditions and drawings.
High-Chromium Cast-Iron Wear Materials May be used for metal working surfaces or composite inserts under severe abrasion and controlled impact. Check fracture risk and support from the surrounding structure.
Wear-Resistant Rubber Liners Offer lower weight, impact cushioning and noise reduction. Select rubber compound and reinforcement for particle size, temperature, slurry, tearing and fastening construction.
Rubber–Metal Composite Liners Combine elastomer support with a metal working surface. Application position, insert alloy, bond design and repair limits require an integrated design.
Magnetic Liner Systems Evaluate only for magnetic ores and suitable mill duties. Captured ferromagnetic material forms a renewing protective layer; this is not a universal solution.
Materials Selected by Zone The shell, lifters, heads, grates and trunnions may use different materials to balance impact, wear, weight, working volume and relining intervals.

Manufacturer technical reference:Metso's published ball mill liner systems include metal, rubber, Poly-Met™ composites, Megaliner™ and Orebed™ for specific duties.

ظروف التشغيل وأنماط الأعطال

Wear profiles reveal more about system problems than a single hardness reading

Measure remaining thickness and profile changes in each zone to assess imbalance in impact, abrasion, discharge, fastening or media movement.

Observed condition الفحوصات ذات الأولوية Material and design considerations
Early lifter height loss and reduced throughput Profile, spacing, speed, filling, balls, feed and worn contour Improve profile retention, toughness and wear resistance; check the liner layout
Cracked or broken liners Large-lump impact, backing support, hole positions, preload, casting defects and excessive hardness Improve toughness and continuous support; check heat treatment, nondestructive testing and fastening
Blocked grates or insufficient discharge capacity Slots, open area, ball size, broken balls, slurry concentration and pulp-lifter capacity Optimise grates, pulp lifters and discharge passages together, rather than simply enlarging openings
Loose bolts and slurry leakage around holes Grip length, washers, seals, lubrication, preload method, seating surfaces and liner fit Restore the complete fastening and sealing system; track materials and preload records by batch
Uneven wear between head and shell liners Uneven feed, discharge backflow, liner transitions, rotation direction and adjacent clearances Coordinate materials and profiles by zone; check the transition between head and shell
