Core Paths for Upgrading and Retrofitting fertilizer production machine:

1. Key Component Replacement: Replacing with high-efficiency, energy-saving motors, variable frequency speed control devices, and optimizing the transmission system can reduce energy consumption in fertilizer produciton lines by 15%-30%. Simultaneously, replacing vulnerable parts with wear-resistant, high-strength materials extends equipment lifespan and reduces maintenance frequency.

2. Energy Recovery and Utilization: Installing waste heat recovery devices on equipment such as dryers and rotary kilns enables cascaded reuse of heat energy; equipping with new insulation materials reduces energy loss and meets green production requirements.

3. Automation and Intelligent Upgrades: Iterating the control system by introducing PLC programmable logic controllers and DCS distributed control systems to achieve automated control of the entire process, including batching, mixing, and granulation. Real-time data collection using sensors allows for precise control of equipment operating parameters.

4. Environmental Optimization: Adopting environmentally friendly coatings and leak-free sealing components, optimizing equipment layout to reduce pollutant diffusion, and ensuring emissions meet environmental policy constraints.

5. Equipment Structure Upgrade: Modular design of core equipment such as NPK fertilizer granulators and mixers, optimizing internal cavity structure, improving material mixing uniformity and granulation qualification rate, thus supporting high-end fertilizer production.

Key Steps for Implementation: Initially, a comprehensive assessment of existing equipment operating conditions, energy consumption, and capacity limitations is conducted; suitable technologies and equipment are researched; differentiated upgrade plans are developed, clarifying budgets and schedules, prioritizing the upgrade of core high-consumption and low-efficiency equipment; after equipment installation and commissioning, trial operation is conducted to verify whether energy consumption, efficiency, and other indicators meet standards; subsequent regular calibration and maintenance are performed.
