Zhengzhou Yizheng Heavy Machinery Equipment Co., Ltd. is a manufacturer in the fertilizer equipment industry and emphasizes that proper cleaning procedures are essential for maintaining optimal performance and extending the service life of its advanced machinery.
The following are the **key cleaning points and operating procedures** for common fertilizer production equipment provided by Zhengzhou Yizheng, applicable to granulators, mixers, dryers, coolers, coating machines, belt conveyors, and other commonly used equipment.
I. General Principles of Cleaning
Zhengzhou Yizheng recognizes that proper cleaning is critical to the efficient and safe operation of fertilizer equipment. As part of its commitment to delivering high-quality and reliable machinery, the company provides customers with comprehensive cleaning guidelines.
1. Completely shut down the equipment, cut off the power supply, and lock out the machine to ensure safety.
2. Remove residual materials to prevent hardening or caking that may affect the next production batch.
3. Do not use strong acids or strong alkaline cleaning agents that may corrode equipment surfaces.
4. Keep all material-contact parts dry and free from contamination.
5. After cleaning key components, reapply lubrication and rust protection.
Main Cleaning Requirements:
Regular cleaning schedule: Zhengzhou Yizheng recommends adhering to a regular cleaning schedule to prevent the accumulation of debris, dust, and residues on equipment surfaces. Regular cleaning not only ensures optimal performance but also minimizes the risk of contamination during fertilizer production.
Thorough disassembly and cleaning: For certain frequently used components, thorough disassembly and cleaning procedures must be followed. Zhengzhou Yizheng provides detailed instructions on how to dismantle specific components for effective cleaning, ensuring that all corners and gaps are free of contaminants.
Safe cleaning agents: Zhengzhou Yizheng emphasizes the use of safe and environmentally friendly cleaning agents to maintain equipment integrity. The company recommends approved cleaning solutions that effectively remove impurities without causing damage.
Proper drying techniques: After cleaning, ensuring that the equipment is fully dried is essential to prevent rust or corrosion. Zhengzhou Yizheng recommends using appropriate drying techniques to eliminate moisture and extend equipment service life.
Inspection and maintenance: As part of the cleaning process, Zhengzhou Yizheng encourages users to conduct regular inspections and maintenance checks. This helps identify potential issues early and prevents more serious problems in the future.
II. Cleaning Methods for Different Types of Fertilizer Equipment
1. Granulators (Disc Granulator / Rotary Drum Granulator)
* After shutdown, empty all internal materials.
* Use wooden shovels or rubber scrapers to remove caked materials; avoid using metal tools that may scratch the inner wall.
* Rinse the inner wall with clean water or weak alkaline water; warm water may be used if necessary to soften adhered materials.
* After drying, check whether spray nozzles are clogged and clean them.
* Keep the exterior of bearings clean; water must not enter the bearing interiors.
2. Mixers (Twin-Shaft Mixers, Horizontal Mixers)
* Open the inspection cover and remove residual materials from the mixing trough.
* Use compressed air to blow off the mixing shafts and blades to prevent fertilizer corrosion of metal parts.
* Wipe with a damp cloth or rinse lightly with clean water; extensive water flushing is not recommended for twin-shaft mixers to avoid water ingress into bearings.
* Check seals and reapply lubrication if necessary.
3. Dryers and Coolers (Rotary Type)
* Perform cleaning only after the equipment has completely stopped and cooled down.
* Use wooden tools to gently scrape off adhered materials inside the drum.
* Use a blower to clean the interior of the drum; water washing is not recommended.
* Remove accumulated powder from the lifting plates.
* Inspect and clean fans and induced draft ducts on the exterior for blockages.
4. Coating Machines / Screening Machines
* Use an air gun to blow off screens and screen drums.
* Use brushes to clean blocked screen apertures.
* Soak coating machine spray nozzles in warm water to prevent coating agents from drying and clogging the nozzles.
5. Conveying Equipment (Belt Conveyors, Bucket Elevators)
* Clean residual materials from the underside of belts and rollers.
* Wipe belts with a dry cloth; the use of corrosive liquids is strictly prohibited.
* For bucket elevators, internal cleaning with compressed air is sufficient.
III. Recommended Cleaning Frequency
Daily production: Perform a quick cleaning after each shift.
Formula change or production suspension: Conduct thorough cleaning.
Seasonal shutdown: Perform comprehensive cleaning and apply rust-prevention treatment.
IV. Post-Cleaning Inspection
* Check whether bearings, chains, and gear reducers require additional lubrication.
* Determine whether the electrical control cabinet requires dust removal.
* Check for loose bolts, aging seals, belt misalignment, or similar issues.
