Operation and Maintenance Essentials Pre-Operation Inspection and Startup Procedures Before operating any compost fertilizer machine – whether a large wheel compost turner or chain compost turner – comprehensive equipment inspection is essential. This includes checking fuel, engine oil, and hydraulic oil levels, along with tire or track pressure conditions. After starting, the windrow machine should idle for 3-5 minutes to ensure turning teeth operate smoothly without jamming, which is crucial for maintaining equipment integrity throughout the organic fertilizer fermentation process. Operational Parameters for Efficient Fermentation During actual operation of the large wheel compost turning machine, turning tooth depth should be adjusted to approximately 80% of pile height. Maintain a consistent speed of 1-2 km/h along the windrow length to ensure materials are thoroughly mixed. Turning frequency must be synchronized with the organic fertilizer fermentation stages: every 3-5 days during high-temperature phase and every 7-10 days during cooling phase. This systematic approach significantly enhances the efficiency of the complete organic fertilizer production line and bio organic fertilizer production line. Maintenance Integration with Production Systems Regular maintenance ensures long-term stability of all equipments required for biofertilizer production. Clean residual materials from turning teeth after each use and regularly inspect for wear. This maintenance philosophy extends to other fertilizer making machine components, including the rotary drum granulator, drum organic fertilizer dryer, and double roller press granulator used in NPK fertilizer production process. Proper care across the entire fertilizer production machine ecosystem – from disc granulation production line to drum granulation systems – maximizes equipment lifespan and production efficiency for sustainable agricultural development.
