Cost of Downtime and Planned Maintenance

Gains:

  • Can calculate the difference between planned and unplanned stopping
  • Can create the content of the maintenance plan
  • Can align maintenance with production plan

In a facility that grinds 300 tons per day, one hour of unplanned downtime means 12.5 tons of production loss. Planned maintenance keeps this loss predictable and small.

Content of planned maintenance

  • Roller trimming schedule (according to surface wear).
  • Screen cloth control and replacement.
  • Bearing lubrication and temperature monitoring.
  • Belt tension and wear control.
  • Aspiration filter cleaning.
  • Magnet and metal separator control (food safety).
  • Scale calibration.

Compliance with production plan

The maintenance window is determined together with the production plan. If there is already a stop for product replacement, placing the maintenance at that window will not create additional downtime.

In a facility where maintenance records are not kept, the question "when did we replace it?" remains unanswered and the part is replaced either early or late. Both are a waste of money.
