Mining & metals: heavy-duty reliability.

Mineral-processing plants run grinding mills, crushers, and conveyors that consume an outsized share of the world's heavy-duty bearing inventory. Droz applies vibration analysis, thermography, and laser alignment to keep this equipment running between major rebuilds — and applies AI to make scheduled-rebuild scope evidence-based.

§ Operating context

Why downtime is brutal here.

Mining-and-metals operations are paid by tonnes throughput — every hour lost to comminution downtime is tonnes unrecoverable in that day.

  • Mill liner cycles. Liner-change windows are immovable; off-cycle mill stops cascade into multi-day production loss.
  • Conveyor critical paths. A single conveyor failure stops every downstream stage.
  • Remote site logistics. Long lead times on heavy spares mean a bearing failure can park a mill for weeks.
  • Energy intensity. Comminution is the single largest energy consumer; misaligned drive trains compound electricity cost.
