Before a long-term shutdown of the organic fertilizer disk granualtor machine, thorough cleaning, rust prevention, protection, and support are necessary to prevent moisture-induced rust, deformation, and component damage, ensuring stable operation upon restart.

First, thoroughly clean the equipment. After shutdown, empty all residual organic fertilizer and slurry from the disc. Rinse the disc body, scraper, drive shaft, and support with clean water, paying particular attention to cleaning accumulated material in corners to prevent clumping and corrosion of the disc surface. After cleaning, allow it to air dry or wipe it dry to keep the interior dry and prevent rust.

Secure rust prevention treatment for key components. Apply rust-preventive oil or grease to metal parts such as the disc surface, scraper, and main shaft. Check and replace the lubricating oil in the reducer and bearing housing, ensuring the oil is clean and the oil seals are in place. Then add grease to seal and prevent moisture ingress.

Properly support and secure the equipment. For long-term shutdown, fix the disc tilt angle in a suitable position and stabilize it with supports to prevent deformation of the cylinder and pins due to prolonged stress. Motors, control boxes, and operating cabinets should be wrapped with waterproof and dustproof covers. Wiring should be checked and secured, and measures should be taken to prevent moisture, rodents, and dust to avoid short circuits and damage.

Regular inspections and maintenance are essential. During fertilizer making machine shutdowns, inspections should be conducted every 15-30 days to check for rust, moisture damage, and deformation. The main shaft and disc should be manually rotated to ensure smooth operation and prevent bearing seizure. For outdoor storage, a rain shelter must be erected, and proper drainage must be ensured. Prolonged exposure to direct sunlight, rain, and immersion in water is strictly prohibited.

A comprehensive inspection should be conducted before startup. Clean and protect the equipment, replace any expired grease, and perform a no-load test run after confirming there are no abnormalities before putting the equipment into production. Proper maintenance can effectively extend equipment life, reduce malfunctions, and lower down repair costs.
