Background
Mellott continually partners with customers to improve crushing efficiency, extend wear life, and lower operating costs. To quantify the real-world performance of Metso’s Long Life liners, Mellott conducted comparative liner scans on both Metso Long Life (LL) liners and a competitor liner set (ME) installed in the same HP400 crusher configuration.
Both liner sets were evaluated using 3D scanning technology to capture wear profiles, remaining material, and operational performance.
Metso HP400 Long Life Liners – Inspection Details
- Crusher Model: Metso HP400
- Chamber Type: SH M
- Bowl Liner: MM2039548
- Mantle: MM2039547
A used set of Metso Long Life liners was scanned to assess wear distribution, liner utilization, and remaining service life.
Competitor HP400 Liners – Inspection Details (ME)
A used set of competitor liners (ME) was also scanned for direct comparison.
- Crusher Model: HP400
- Chamber Type: SH M
- Bowl Liner: 1048300035 (Short Head Medium Bowl Liner)
- Mantle: 7055308387* (STD Fine Mantle)
The competitor bowl liner was identified as a Short Head Medium profile, while the mantle utilized a Standard Fine profile.
