Hollow Paddle Dryer Post-Purchase Support: Seamless Setup & Maintenance Guide

To ensure your Hollow Paddle Dryer delivers high-efficiency drying and reliable long-term performance, our team provides full lifecycle service support. Below is your quick action guide for smooth installation, routine maintenance, self-troubleshooting, and warranty service.

1. Unpacking & Installation Guide

Upon receiving your drying system, follow these essential steps to ensure optimal setup:

• Inspection: Check the outer structure, drive unit, and accessories for any transportation damage. Verify parts against the packing list.

• Foundation & Leveling: Place the unit on a solid, level concrete foundation to minimize vibration and tension on connecting pipes.

• Piping Connection: Connect the heating medium (steam, thermal oil, or hot water) and material feed/discharge pipelines securely, ensuring leak-free sealing.

• Trial Run: Rotate the paddle shaft manually before turning on power to verify free rotation. Run the machine empty for 30 minutes to confirm stability.

2. Routine Maintenance Practices

Proper daily maintenance extends operational life and lowers long-term operating costs:

• Lubrication: Lubricate main bearings and drive gearboxes every 500 operating hours with recommended high-temperature grease.

• Seal & Valve Check: Regularly inspect rotary joints and mechanical shaft seals for leakage. Tighten or replace seals promptly if worn.

• Cleaning: Clean internal paddle surfaces and heating troughs periodically to prevent material buildup and maintain optimal thermal efficiency.

3. Quick Troubleshooting & Self-Check Solutions

Resolve common operational issues fast with these initial self-checks:

• Abnormal Shaft Vibration / Noise: Check for loose mounting bolts, bearing wear, or unbalance caused by uneven feeding.

• Decreased Heating / Drying Efficiency: Inspect steam traps for clogging, or check for scale/material buildup on paddle surfaces.

• Rotary Joint Leakage: Tighten gland bolts slightly. If leakage persists, replace internal graphite seal rings.
