Double roller press granulators are widely used in fertilizer, feed, and chemical industries. Proper maintenance of their core parts directly impacts production efficiency and granule quality.

1.Roller Maintenance

Regular Lubrication: Check the lubrication system every shift. Ensure bearings and gears are well-lubricated to reduce friction and wear.

Even Wear: Adjust roller gaps regularly to prevent uneven wear and extend service life.

Clean After Use: Clear double roller press granulator’s residual material after shutdown to prevent corrosion or buildup affecting the next run.

2.Die (Ring Die/Flat Die) Care

Check Wear Periodically: Clean or replace dies immediately if holes are blocked or severely worn. This avoids efficiency loss.

Rust Prevention During Idle Time: Apply anti-rust oil to die surfaces during long shutdowns to prevent corrosion.

Proper Operation: Avoid overloading to reduce deformation risks from high heat or pressure.

3.Transmission System Upkeep

Check Belt/Chain Tension: Loose parts cause slippage; overtightening increases wear. Adjust tension regularly.

Gearbox Oil Change: Replace lubricant every 2,000 operating hours or every 6 months to maintain efficiency.

Motor Cooling: Prevent motor burnout by avoiding prolonged overload operation.

4.Feeding System Care

Clean Regularly: Clear the feed inlet and screw conveyor after each shift to prevent material buildup.

Seal Checks: Ensure no leaks or dust spills to reduce wear and environmental impact.

Following these maintenance practices will significantly improve your double roller press granulator’s efficiency and cut repair costs.
