What to do if your flat die pellet machine is blocked? 3 major causes + solutions

Raw Material Moisture Content Control (Optimal 8%-15%)

1.Excessive Moisture Content:

· Symptoms: Material sticks to the mold, resulting in loose, easily broken material

· Solution: Air the raw materials or add drying additives

· Testing Method: Hand-knead into a ball, ideally, it should fall apart when dropped to the ground

2. Excessive Moisture Content:

· Symptoms: Excessive powder, making molding difficult

· Solution: Spray with atomized water or steam conditioning

· Note: Add water evenly to avoid over-wetting in certain areas

Matching Feed Rate with Mold Aperture

1. Improper Feed Rate:

· Too fast: Exceeds mold processing capacity

· Too slow: Idle machine damages the mold

· Recommendation: Calibrate a uniform feed rate based on production capacity

2. Mold Aperture Selection Selection:

· Raw material properties determine the aperture size

· Regularly clean the mold to remove any remaining hard lumps;

· Grind new molds for at least 20 minutes before use to ensure smooth hole walls;

· Regularly inspect mold wear

Comprehensive Solution

1. Pretreatment System:

· Install a raw material screening and iron removal device

· Install a moisture detector for real-time monitoring

2. Operating Standards:

· Idle the machine for preheating before startup

· Punch the holes with oil before shutting down to prevent mold blockage

· Regularly maintain the mold rollers

3. Emergency Measures:

· Immediately shut down the machine in the event of a material blockage

· Disassemble and clean the mold

· Inspect the drive system

Following these key points can reduce the risk of material blockage by over 90%. Users are advised to establish a preventive maintenance system and regularly record equipment operating parameters to ensure stable production.
