Mill liners
Durable Mill Liners for Extreme Wear
Mill liners are critical for maintaining operational efficiency in grinding mills, enduring significant wear. Stancor's abrasion-resistant plates provide optimal protection against wear mechanisms.
The wear problem
In grinding operations, mill liners face severe sliding abrasion and impact wear due to the constant movement of materials and grinding media. This leads to premature liner failure, often seen as cracks and excessive wear on the liner surface.
Recommended plate by component
| Component | Grade | Thickness | Why |
|---|---|---|---|
| Mill Liner | Stanhard 450 (450 HBW) | 20-50 mm | Optimized for sliding abrasion, providing extended service life. |
| End Liner | Stanhard 500 (500 HBW) | 30-60 mm | Enhanced impact resistance, reducing frequent replacements. |
| Lifter Bar | Stanhard 550 (550 HBW) | 25-55 mm | Improves mill efficiency while minimizing wear. |
| Trunnion Liner | Stanhard 575 (575 HBW) | 25-50 mm | Provides excellent resistance to gouging and cavitation. |
| Shell Plate | Stanhard 600 (600 HBW) | 30-70 mm | Superior abrasion resistance supports longer replacement intervals. |
Selecting the right plate
Assess mill type
Different mill designs may require specific liner configurations for optimal performance.
Consider material flow
Understanding the material characteristics helps determine the right grade and thickness.
Evaluate impact forces
Higher impact forces necessitate liners with enhanced toughness and wear resistance.
Review replacement frequency
Select grades that prolong liner life to reduce maintenance downtime.
Questions engineers ask
What wear mechanism should I focus on?
Focus on sliding abrasion and impact wear for mill liners. Identifying the primary wear mode helps in selecting the appropriate material grade.
How do I choose the right thickness?
Thickness requirements depend on the specific application and wear rates. Consult with an engineer for tailored recommendations.
What is the lifespan of the liners?
Lifespan varies based on material handling, grade selection, and operating conditions. Proper selection can significantly extend service life.
