Avoid undetected issues

With commodities at peak prices, you will want to push your grinding mills to the limit. This may cause issues that can go undetected, such as:

  • Drive train misalignment
  • Damaged gear & pinion teeth
  • Wash inside the mill
  • Foundation and soleplate degradation
  • Bearing & gear lubrication system problems and leaks
  • Structural failures: shells, heads, gears, trommels, etc.
  • Missing or broken bolts on joints or liners
  • And many others

These can lead to increased repair costs, HSE problems, unplanned downtime and production losses at your production plant.

We offer three progressive mill inspection packages to check the health of your horizontal grinding mills, detect problems early and meet your sustainability goals. Each package consists of additional inspection points that include summary reports with the collected data and expert recommendations.
Our Grinding Mill Inspection packages can help you save between 200.000 and 1.000.000 Euro per day of unplanned mill failure.
