Rust Prevention Treatment for Long-Term Shutdown of Bio Disk Organic Fertilizer Machine
Before long-term shutdown of bio disk organic fertilizer machine, rust prevention is a core maintenance step. Properly performing the four steps of cleaning, drying, oiling, and sealing can effectively prevent rust and deformation of the disc surface, main shaft, bearings, and transmission components.
First, thoroughly clean and dry. All organic fertilizer residue, dust, and slurry must be completely cleaned from the inside of the disc, scraper, frame, and transmission shaft. Storage with material present is strictly prohibited. Materials easily absorb moisture and corrode metal; after cleaning, wipe dry with a dry cloth or allow to air dry naturally to ensure the disc granulator is completely dry. This is the foundation of rust prevention.
Rust prevention for the disc surface and metal structure. Apply rust-preventive oil or industrial grease evenly to all exposed metal surfaces, including the inner wall of the disc, outer ring, scraper, bracket, and flanges, to form a sealed protective film. Pay special attention to welds, corners, bolts, and other easily rusted areas, applying a thicker layer to prevent moisture intrusion and rust.
Rust prevention for transmission and rotating components. For components such as the main shaft, bearing housings, pins, and universal joints, clean them first, then add sufficient high-temperature grease to fill the bearing clearances and isolate them from air and moisture. Replace the lubricating oil in the reducer, and seal the vents to prevent water and dust from entering and causing internal corrosion. Clean the chain and gears, apply grease, and wrap them tightly with waterproof cloth or plastic film.
For motor and electrical control system rust prevention, wipe the motor surface clean, seal the junction box, and wrap the entire unit with a rainproof and dustproof cover. Close and lock the electrical control box and control cabinet, place a desiccant inside, and cover them with protective covers to prevent moisture and short circuits.
During long-term downtime, it is recommended to check the rust-preventive coating every 15-30 days and reapply if the oil film is damaged. Outdoor storage must be covered with a rainproof shed to avoid rain and direct sunlight. Before starting the machine, wipe off the surface rust-preventive oil, check the bearing lubrication, and test the machine under no-load until it is normal before commencing production. Proper rust prevention can significantly extend the service life of equipment and reduce downtime.
