Heat is the first enemy
Bulk cement is discharged with hot compressed air. A hose rated for at least 180 degrees Celsius protects the rubber from hardening and cracking.
Do not over-pressurise the line
Pressure spikes at the start and end of discharge stress the reinforcement. Open and close valves slowly so the hose sees a smooth pressure curve.
Support the full length
- Suspend the hose so the weight does not hang on the coupling
- Keep the bend radius above the manufacturer minimum
- Never drag a charged hose across the ground
Retire it on schedule
Even a well-run hose ages. Log the hours in service and replace the hose before the cover shows deep cracks, because a failure during discharge is far more costly than a planned replacement.
