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.
