Understanding Cone Liner Wear: Metallurgy & Application Science
Cone crusher liners endure severe compression and abrasion inside a narrow annular chamber. Understanding the wear mechanisms and metallurgical response helps you select the optimal manganese grade for maximum service life.
Austenitic manganese steel’s unique work-hardening property makes it ideal for cone crushers: the repeated compression cycles cause the surface to harden from HB 200-240 to HB 450-580, creating a hard outer shell while the core remains tough and ductile.
🔬 Work-Hardening Mechanism
- Austenitic transformation: Compression converts austenite to martensite at the surface, increasing hardness 2-3× without heat treatment.
- Depth of hardening: Typically 3-8mm depending on impact intensity and manganese content.
- Critical requirement: Sufficient loading intensity to activate work-hardening—starved feed prevents this transformation.
⚙️ Compression vs. Impact Loading
- Cone crushers: Primarily compression wear with moderate abrasion—manganese steel optimal.
- Higher Mn content (Mn18, Mn22): Improves work-hardening response under consistent loading.
- Shock events: Mn22 provides maximum toughness to resist cracking from tramp metal or oversize feed.
📊 Manganese Grade Selection Logic
- Mn13: Variable loading, intermittent operation, softer rock, budget-conscious applications.
- Mn18: Industry standard for granite, basalt, hard rock—optimal balance of toughness and wear resistance.
- Mn22: Severe shock probability, coarse chambers, mining applications with tough ore.
- Mn + TiC: Abrasive feeds where edge rounding limits life, tertiary/fine crushing.
⚠️ Glazing Prevention
- Cause: Operating without choke feed prevents work-hardening activation.
- Result: Polished, smooth surface with low hardness (HB 250-300)—wear accelerates 3-5×.
- Prevention: Maintain 60-80% chamber fill level; never run crusher empty except during shutdown.
- Once glazed: Irreversible—liner must be replaced; cannot recover hardness.
Decision Matrix: Selecting Optimal Cone Liner Material
Match your application profile to the right manganese grade and optional TiC reinforcement for maximum ROI.
Hard Rock Secondary (Granite, Basalt)
Start: Mn18—industry standard, excellent work-hardening. → Upgrade: Mn18+TiC if edge rounding limits life. Maximum: Mn22 if shock events are common.
Typical life: 1,100-1,850 hours. Maintain choke feed for proper work-hardening.
Limestone & Softer Rock
Start: Mn13—sufficient for moderate abrasion, cost-effective. → Upgrade: Mn18 if wear exceeds expectations. Maximum: TiC usually not justified.
Typical life: 1,200-1,800 hours. Lower hardness rock requires less manganese.
Tertiary/Manufactured Sand (Tight CSS)
Start: Mn18—standard choice for fine crushing. → Upgrade: Mn18+TiC for abrasive feeds (granite, quartzite). Maximum: TiC essential for manufactured sand.
Typical life: 600-1,400 hours. Tight CSS intensifies wear—TiC ROI highest here.
Recycled Concrete & Asphalt
Start: Mn18—good abrasion resistance for clean recycling. → Upgrade: Mn22 if rebar cannot be fully removed. Maximum: TiC only with excellent metal detection.
Typical life: 800-1,400 hours. Metal detection critical for TiC success.
Variable/Mixed Feed Operations
Start: Mn18—most versatile choice. → Upgrade: Mn22 if shock events increase. Maximum: Avoid TiC in uncontrolled feed.
Typical life: 900-1,400 hours. Mn18 tolerates feed variability better than specialized alloys.
Coarse Primary Cone (EC/C Chambers)
Start: Mn22—maximum toughness for large feed and shock. → Upgrade: Not typically applicable. Maximum: TiC not recommended for coarse duty.
Typical life: 1,100-1,750 hours. Toughness priority over edge retention.

Why TiC Insert Cone Liners Deliver Quantifiable Extended Wear Life
Titanium Carbide (TiC) inserts address the primary failure mode in abrasive cone crushing applications: edge rounding. While the manganese matrix handles compression forces, TiC rods (HV 2800-3200) protect high-wear strike zones, extending liner life by 40-60% in appropriate applications. The cast-in TiC maintains mechanical bond with the manganese steel, providing superior retention compared to brazed or mechanically fastened carbide solutions.
How TiC Inserts Work in Cone Liners
- Targeted protection: TiC rods placed at high-wear zones (crushing edges, CSS region) where abrasive wear is most intense.
- Composite action: Manganese matrix carries compression loads; TiC resists abrasive gouging and edge erosion.
- Work-hardening preserved: Manganese between TiC rods continues to work-harden normally—best of both materials.
- Edge retention: Maintains CSS longer between adjustments, more consistent product gradation.
Optimal TiC Applications for Cone Crushers
- Tertiary/fine crushing: Tight CSS (6-19mm) intensifies edge wear—TiC ROI highest here.
- Abrasive feeds: Granite, basalt, quartzite, manufactured sand where edge rounding limits life.
- Controlled operations: Good tramp metal detection, consistent feed, minimal shock events.
Best-fit ATF alloys: Mn18+TiC for most applications; Mn22+TiC for shock-prone abrasive duty.
When NOT to Use TiC in Cone Crushers
- Uncontrolled tramp metal: Steel impacts cause TiC spalling—$2,000-$4,000 premium wasted.
- Recycling without metal detection: Rebar and embedded steel destroy TiC inserts rapidly.
- Coarse/EC chambers: Edge retention less critical than overall toughness; Mn22 better value.
- Low-abrasion materials: Limestone, soft rock—TiC premium not justified by wear improvement.
Critical Warning: TiC performs best with metal detection systems. Without tramp control, standard Mn18 or Mn22 provides better economics.

When to Replace Cone Crusher Liners — Critical Indicators
Understanding when to replace cone crusher liners prevents catastrophic crusher damage and maintains consistent product gradation. Replace mantles and concaves based on condition monitoring—not arbitrary schedules.
📏 Liner Thickness Minimum by Crusher Size
Critical Rule: Replace when remaining thickness reaches 30-35% of original specification
Mantle Minimum Thickness by Model:
- HP200/CH420: Replace mantle at 25-30mm remaining thickness
- HP300/CH430: Replace at 30-35mm remaining
- HP400/CH440: Replace at 35-42mm remaining
- HP500/CH660: Replace at 42-50mm remaining
- HP800/CH880: Replace at 50-65mm remaining
Concave (Bowl Liner) Minimum Thickness:
- Concaves typically last 2-3 mantle changes before replacement
- Replace when remaining thickness reaches 35-40% of original
- Never pair new mantle with worn concave below 50% thickness
Measurement Method: Use ultrasonic thickness gauge at 3-4 locations around circumference. Document readings every 200-300 hours.
📊 CSS Drift Monitoring
Symptom: CSS increases beyond target despite adjustment attempts
Normal CSS Drift Ranges:
- 0-300 hours: 1-2mm drift (normal wear-in)
- 300-600 hours: 2-4mm drift (moderate wear)
- 600-900 hours: 4-6mm drift (approaching replacement)
- >900 hours or >6mm drift: Replacement recommended
Best Practice: Measure CSS weekly using lead crushing method. Document baseline when new liners installed.
👁️ Visual Wear Patterns
Inspection Points: Check during every scheduled maintenance shutdown
- Pocketing (Deep Grooves): Feed segregation or oversized material. Replace immediately.
- Profile Loss: Rounded edges and flattened surface. Replace at 70% wear.
- Uneven Wear: One-sided pattern indicates feed distribution problems.
- Glazing: Smooth, shiny surface with low hardness. Replace immediately.
- Visible Cracks: Any crack >10mm requires immediate replacement.
📉 Performance Degradation
Monitor these metrics weekly:
- Throughput Changes: 10-15% reduction at same CSS = replacement time
- Power Consumption: 10-20% higher amp draw at same tonnage
- Product Quality: Increase in oversize material, gradation shift
- Crusher Behavior: Unusual vibration, hydraulic pressure fluctuations
⏱️ Operating Hours Baseline
Use these ranges to plan inventory and budget:
Secondary Crushing:
- Granite/Basalt: Mn18 mantle 800-1,200 hours
- Limestone: Mn18 mantle 1,200-1,800 hours
- With TiC: Add 40-60% to base hours in clean applications
Tertiary/Fine Crushing:
- Tight CSS (6-13mm): Mn18 mantle 600-1,000 hours
- Manufactured Sand: Mn18+TiC mantle 900-1,400 hours
⚠️ Safety & Damage Costs
Critical: NEVER operate with these conditions:
- Exposed Seating: Metal-to-metal contact. Risk: Frame/shaft damage.
- Visible Cracks: Risk: Catastrophic failure.
- Severe Pocketing: Risk: Bearing failure.
Cost of Operating Past Liner Life:
- Minor Frame Damage: $15,000-$30,000
- Head Ball Replacement: $25,000-$50,000
- Main Shaft Damage: $40,000-$80,000
- Catastrophic Failure: $150,000-$300,000+
Chamber Selection Guide — Matching Profile to Application
Correct chamber selection determines feed acceptance, reduction ratio, throughput capacity, and product gradation. Chamber profile is defined by the mantle and concave geometry combination.
Chamber Designations
- EC (Extra Coarse): 150-250mm feed, 35-70mm CSS, maximum tonnage
- C (Coarse): 100-200mm feed, 25-50mm CSS, high capacity secondary
- M (Medium): 60-150mm feed, 16-38mm CSS, most versatile
- F (Fine): 35-100mm feed, 10-25mm CSS, tighter gradation
- EF (Extra Fine): 25-75mm feed, 6-16mm CSS, manufactured sand
Selection Rules
- Feed size rule: Feed F80 should be 60-80% of chamber opening
- Product relationship: Product P80 ≈ CSS × 0.75
- Reduction ratio: Most cones operate at 3:1 to 6:1
- Match feed 80% passing to chamber opening
Profile Geometry
- Step profile: Higher throughput, better for coarse feeds, more flaky product
- Smooth profile: Superior cubicity, uniform product, 5-10% lower capacity
- Step for secondary crushing; smooth for tertiary/shape-critical
Common Mistakes
- Oversized chamber: Feed too small causes bottom wear, capacity loss
- Too-fine chamber: Excessive recirculation, 40-60% returns
- Aggressive profile for shape: Using step profile for manufactured sand
- Ignoring circuit: Chamber selected without considering upstream/downstream
| Application | Feed Material | Recommended Chamber | CSS Range | Liner Material |
|---|---|---|---|---|
| Secondary Crushing | Granite, Basalt | C or M | 22-32mm | Mn18 or Mn22 |
| Secondary Crushing | Limestone | C or M | 25-38mm | Mn13 or Mn18 |
| Tertiary Crushing | Hard Rock | M or F | 12-19mm | Mn18 + TiC |
| Manufactured Sand | Any Abrasive | F or EF | 6-13mm | Mn18 + TiC |
| Recycled Concrete | Concrete, Asphalt | M or C | 19-32mm | Mn18 or Mn22 |

| Manufactured Sand | EF | Mn18 + TiC | 700-1,100 | 1,750-3,300 | TiC essential; very tight CSS; clean feed |
| Recycled Concrete | M | Mn18 or Mn22 | 800-1,400 | 2,000-4,200 | Remove rebar upstream; avoid TiC if steel risk |
| Mixed Aggregates | M | Mn18 | 900-1,400 | 2,250-4,200 | Versatile; tolerates feed variability |
| Primary Cone (Coarse) | EC | Mn22 | 1,100-1,750 | 3,300-5,250 | Maximum toughness; avoid starved feed |
Troubleshooting Cone Liner Wear: Diagnostics & Solutions
Abnormal wear patterns indicate operational issues that reduce liner life and crusher efficiency. Diagnose root causes before installing new liners to prevent repeat failures.
🔍 Problem: Pocketing (Deep Grooves)
Symptoms: Deep grooves in liner surface; localized wear 3-5× normal depth; visible pockets where material pools.
Likely Causes:
- Feed too fine for chamber (material pooling in zones)
- Segregated feed (coarse/fine separation before crusher)
- Chamber too coarse for product requirements
Solutions:
- Install scalping screen to remove fines (<10mm)
- Change to finer chamber (C→M or M→F)
- Improve feed distribution (center feed point)
🔍 Problem: One-Sided Wear
Symptoms: One side worn 30-50% more than opposite; visible thickness difference; unbalanced discharge.
Likely Causes:
- Off-center feeding (most common—60% of cases)
- Feed segregation on conveyor belt
- Damaged/missing feed distributor (spider)
Solutions:
- Adjust feed chute to center discharge point
- Replace/repair feed distributor spider
- Add deflector plates to center material flow
🔍 Problem: Glazing (Polished Surface)
Symptoms: Smooth, shiny surface; low hardness (HB 250-300 vs. 450-550 expected); material slipping in chamber.
Likely Causes:
- Starved feed (chamber <60% full)
- Feed too fine for chamber opening
- Improper run-in procedure (new liners)
Solutions:
- CRITICAL: Glazing is irreversible—replace liners immediately
- Install chamber level indicator; maintain 60-80% fill
- Follow 16-hour run-in protocol for new liners
🔍 Problem: Excessive CSS Drift
Symptoms: CSS increases 5-10mm despite adjustment; product becomes coarser; recirculation increases.
Likely Causes:
- Normal liner profile wear (expected progression)
- Backing compound failure (liner shifting)
- Bowl ring slippage or hydroset pressure loss
Solutions:
- Weekly CSS adjustment to compensate for wear
- Check backing compound integrity at next change
- Verify hydroset pressure (HP/GP) or spring tension
🔍 Problem: Liner Cracking
Symptoms: Visible cracks; chunks in discharge; sudden vibration increase; metallic sounds.
Likely Causes:
- Tramp metal/uncrushables exceeding material limits
- Casting defects (internal voids)
- Operating past wear limit (<30% remaining)
- Thermal shock (cold water on hot liner)
Solutions:
- IMMEDIATE SHUTDOWN—inspect for frame damage
- Install metal detector upstream ($15,000-$30,000)
- Replace at 70% wear to prevent structural failure
- Request ultrasonic testing certificates from supplier
🔍 Problem: Rapid Top Wear
Symptoms: Excessive wear in upper third; bottom shows minimal wear; bridging at feed opening.
Likely Causes:
- Oversized feed (>85% of chamber opening)
- Chamber too fine for feed size
- Poor scalping—oversize not removed upstream
Solutions:
- Install grizzly/scalper to remove oversize
- Change to coarser chamber (F→M or M→C)
- Reduce primary crusher CSS to control feed size

What’s the difference between a mantle and a bowl liner (concave)?
The mantle is the moving cone-shaped wear part that sits on the main shaft head and gyrates inside the crushing chamber. The bowl liner (also called concave) is the stationary outer wear part that lines the upper frame.
- Mantle: Inner moving cone, mounted on main shaft head
- Concave: Outer stationary ring, lines the bowl assembly
- Crushing action: Material compressed between mantle and concave
- Wear ratio: Mantle typically wears 2-3× faster than concave
When should I replace cone crusher liners?
Replace when remaining thickness reaches 30-35% of original specification. Key indicators:
- Thickness: 30-35% remaining (measure with ultrasonic gauge)
- CSS drift: 3-4mm beyond target despite adjustments
- Throughput: 10-15% reduction at same settings
- Power: 10-20% higher amp draw at same tonnage
- Visual: Pocketing, cracks, or severe glazing
Critical rule: Replace at 70% wear to protect crusher internals. Operating worn liners to 100% can cause $50,000-$200,000 in crusher damage.
Why do cone liners glaze or polish?
Glazing (smooth, polished surface) occurs when manganese steel doesn’t work-harden properly. Common causes:
- Starved feed: Crusher running without choke feed (chamber <60% full)
- Under-loading: Operating below 50% power capacity
- Feed too fine: Material size doesn’t match chamber opening
- Improper run-in: New liners not properly broken in
Prevention: Maintain 60-80% chamber fill, follow 16-hour run-in protocol. Critical: Glazing is irreversible—liner must be replaced immediately.
When should I choose TiC inserts for cone liners?
Choose TiC inserts when edge rounding (not overall thickness loss) limits liner life:
- Best for: Granite, basalt, quartzite (high abrasion); tertiary/fine crushing with tight CSS
- ROI: TiC adds 30-40% to cost but extends life 40-60% in appropriate applications
- Requirement: Good tramp metal control (metal detection recommended)
Avoid TiC if: Frequent uncontrolled tramp events; recycled concrete with rebar; lower-abrasion materials where TiC premium isn’t justified.
Do I adjust CSS as cone liners wear?
Yes, CSS adjustment is essential. As liner profile wears, the effective crushing gap widens, producing coarser product.
- Measurement: Use lead crushing method weekly
- Baseline: Document CSS when new liners installed
- Adjustment: Close CSS 1-2mm as wear progresses
- Normal drift: 2-4mm over liner life is typical
Hydroset crushers (HP/GP) auto-compensate; spring cones require manual adjustment via adjustment ring.
Can I pair a new mantle with a worn concave?
No—never pair new mantle with worn concave (or vice versa). Profile mismatch causes:
- 15-25% reduction in throughput capacity
- Accelerated wear on the new liner (30-50% faster)
- Inconsistent product gradation
- Potential frame damage from uneven loading
Replacement ratio: Typical 2:1 or 3:1 (2-3 mantles per concave). Replace concave at 70% wear even if mantle was just installed.
How long do cone crusher liners typically last?
Service life varies dramatically by application (600-2,500 hours typical range):
- Granite/Basalt secondary: 800-1,200 hours (Mn18 mantle)
- Limestone secondary: 1,200-1,800 hours
- Tertiary crushing: 600-1,000 hours (higher wear intensity)
- With TiC inserts: Add 40-60% to base life
Key factors: Rock abrasiveness, chamber type, CSS, feed quality, and operational discipline.
Are ATF cone liners compatible with OEM crushers?
Yes. ATF cone crusher liners are engineered to OEM specifications and are 100% interchangeable with original parts.
- Compatible with: Metso HP/GP/MP, Sandvik CH/CS, Symons 2′-7′, Terex, Telsmith, Trio, 50+ brands
- Quality assurance: CMM dimensional verification, pattern verification against OEM drawings
- Certification: ISO 9001 certified manufacturing
How much do cone crusher liners cost?
Pricing varies by crusher model, chamber type, and material specification:
- HP200 mantle: $2,800-$4,200
- HP400 mantle: $8,500-$12,000
- HP800 mantle: $28,000-$38,000
- TiC inserts: Add 30-40% to base cost
ATF typically saves customers 25-40% vs. OEM while maintaining equivalent or superior performance. Contact us for accurate pricing.
What is the difference between Mn13, Mn18, and Mn22 manganese steel?
The numbers indicate manganese content percentage:
- Mn13 (11-14% Mn): General-purpose, good toughness, cost-effective for softer rock
- Mn18 (17-19% Mn): Industry standard—optimal work-hardening for most hard rock applications
- Mn22 (20-24% Mn): Maximum toughness for shock-prone applications and coarse chambers
All grades work-harden from HB 200-240 (as-cast) to HB 450-580 (in-service). Higher Mn increases work-hardening potential but also cost.
Can I install cone crusher liners myself?
Experienced maintenance teams can install cone liners following proper procedures. Critical requirements:
- Lifting equipment: Overhead crane (mantle 200-2,000kg)
- Tools: Calibrated torque wrenches, backing compound applicators
- Measurement: CSS verification equipment (lead crushing)
- Documentation: We provide detailed installation manuals with torque specs
For first-time installations, we can arrange supervised installation or training. Improper installation voids warranty.
How do I calculate cost per ton for cone crusher liners?
Formula: Cost per ton = (Liner Set Cost) ÷ (Total Tons Crushed)
Example calculation:
- HP400 Mn18 mantle cost: $8,500
- Expected life: 1,000 hours at 150 TPH = 150,000 tons
- Mantle cost per ton: $8,500 ÷ 150,000 = $0.057/ton
- Add concave cost (~$0.048/ton) for total: ~$0.105/ton
Don’t forget to factor in downtime costs and labor for liner changes when comparing options.
How often should I adjust CSS on cone crushers?
Weekly CSS adjustment is standard practice for most operations:
- Weekly: Standard practice—measure CSS, adjust 1-2mm closed
- Daily: For critical applications (manufactured sand)
- Bi-weekly: Acceptable for non-critical applications
Method: Lead crushing method is most accurate. Normal drift is 1-2mm per 300 operating hours. Replace liners when adjustment range exhausted.
Should I replace mantle and concave at the same time?
No—replace on different schedules based on actual wear.
- Replacement ratio: Mantles wear 2-3× faster; typical 2-3 mantles per concave
- Decision matrix: If concave >65% worn when mantle needs replacement, replacing both may be economical
- Critical rule: Never pair new mantle with worn concave (<50% remaining)
Calculate: Cost of “wasted” concave life vs. cost of second shutdown (downtime + labor) to determine best approach.
What’s the difference between Metso HP and GP series cone crushers?
HP (High Performance) and GP (General Purpose) are designed for different applications:
- HP Series: Maximum throughput, large quarry/mining applications
- GP Series: Greater versatility, varying applications
- Critical: HP and GP liners are NOT interchangeable—even for similar model numbers
Always specify exact model (HP vs GP) when ordering liners. HP200 and GP200 use completely different liner designs.
What information do I need to provide for a cone liner quote?
For accurate quotes, provide:
- Essential: Exact crusher model (HP200, CH430, etc.), chamber type (C, M, F, EF)
- Helpful: Serial number, current liner part numbers, quantity needed
- For recommendations: Feed material, current liner life (hours), wear patterns
Photos of existing liners showing wear patterns help us recommend optimal material grade (Mn13/Mn18/Mn22/TiC).
