Safe operating guidelines for disc granulators in fertilizer granulation

As a core piece of equipment in organic fertilizer production lines, the safe operation of disc granulators directly impacts productivity, product quality, and personnel safety. Following standardized procedures not only extends equipment life but also effectively prevents hazards like mechanical injuries and electrical accidents.

1.Pre-Startup Checks  

Mechanical parts: Ensure key components like the granulation disc, scraper, and drive assembly are securely fastened, with no looseness or wear.  

Lubrication system: Verify adequate oil levels at all lubrication points; confirm bearings, gears, and other transmission parts are well-lubricated.  

Electrical system: Inspect motor wiring for integrity, check that grounding protection is functional, and ensure control panels show no abnormalities.

2.Safety During Operation  

Feeding method: Maintain consistent material feed to avoid pile-ups that could overload the motor.  

Speed control: Adjust rotation speed based on material properties; strictly prohibit exceeding rated speeds.  

Handling abnormalities: Immediately shut down if abnormal vibrations or noises occur; resume only after troubleshooting.  

Safety guards: Never remove protective covers during operation; keep body parts away from rotating components.  

3.Maintenance Essentials  

Power off: Always cut power and hang warning signs before performing maintenance.  

Safe cleaning: Use dedicated tools to clean the disc; never remove caked material by hand.  

Regular inspections: Implement a checkpoint system focusing on wear-prone parts.  

4.Personal Protection  

Operators must wear work uniforms, helmets, dust masks, and other protective gear.  

Personnel with long hair must secure it to avoid entanglement in moving parts.  

Gloves are prohibited when handling rotating equipment to prevent entanglement risks.

By implementing these safety measures, businesses protect workers, improve disc granulators efficiency, reduce maintenance costs, and achieve a win-win for safety and productivity.
