Bio organic fertilizer equipment is susceptible to problems such as adhesion, wear, and clogging due to high humidity and the characteristics of the materials containing microbial agents. Scientific maintenance not only extends the equipment's lifespan but also ensures the production efficiency and microbial activity of the bio organic fertilizer production line, reducing operating costs. Maintenance should follow the principles of "cleaning first, lubrication second, regular inspection, and protection as needed," combining daily operation and periodic maintenance to accurately avoid potential malfunctions.
Daily maintenance is fundamental and should be carried out throughout the entire bio organic fertilizer production process. Before starting the machine, clean impurities from the feed inlet, check the smooth operation of the spray humidification system, and verify that the lubricating oil level in the bearing box meets the standard, ensuring that there is no damage to the electrical wiring. After shutting down, thoroughly clean residual materials from the granulation chamber, cutter arms, and screens to prevent the growth of miscellaneous bacteria, corrosion of the equipment, or clogging during the next startup. Simultaneously, wipe the equipment surface and frequency converter with a dry cloth and take precautions against moisture.
Regular inspections should be conducted periodically, focusing on vulnerable parts and core systems. Weekly, check the tightness of fasteners and apply rust inhibitor, and clean the discharge screen. Monthly, replenish high-temperature grease for bearings, gears, and other transmission components, and check the motor's operating current. Quarterly, replace easily worn parts such as cutter arms, clean scale buildup on the inner wall of the equipment, and calibrate operating parameter instruments. When lubricating, use grease suitable for high-temperature conditions to avoid affecting microbial activity.
Special protection should not be overlooked and should be adapted to different scenarios. In cold regions, antifreeze measures should be taken in winter. When the equipment is idle, thoroughly clean it and cover it with a dust cover. For long-term shutdowns, disassemble easily deformed or easily lost parts and store them properly, and establish an equipment log. At the same time, pay attention to any abnormal noises or vibrations during equipment operation, record and investigate them promptly to prevent minor malfunctions from escalating.
Scientific maintenance is a guarantee for large-scale production of bio organic fertilizer, reducing downtime losses and improving product quality. Companies should develop a customized maintenance plan based on the equipment manual and production conditions, implement full-process maintenance responsibilities, and maximize equipment efficiency.
