Daily
- Walk the plant: listen for unusual noise and check for vibration and heat at bearings
- Check roller mill feed and grinding, and look for flour leaks at sifters and spouts
- Confirm filter differential pressure and fan operation
- Keep the building clean to reduce infestation risk
Weekly
- Inspect plansifter and purifier sieves (bolting cloth) and sieve cleaners
- Check belts, chains and couplings on conveyors and elevators
- Clean spouts and pipes; a mill spout cleaner helps reach inside
- Check slide gates and level sensors
Periodic
- Roll condition: re-fluting or grinding as needed
- Bearing lubrication as per manual
- Filter sleeve cleaning or replacement
- Calibration of feeders and dosing (micro feeder)
Keep critical spares
Keep spare sieve frames and cloth, belts, bearings, filter sleeves and a set of rolls for critical passages. Downtime usually costs more than the spare.
Plan service support
Agree service visits and spare-part supply with your machine supplier. DPG provides spare parts and after-sales service for its machines.
