To ensure the long-term, efficient, stable, and smooth operation of a roller press granulator produciton line, a systematic management approach is needed across five key aspects: raw materials, equipment, process, operation, and maintenance. This will achieve continuous, stable production, low failure rates, and high pellet yield.

Raw material pretreatment is fundamental. Strictly control the moisture content, fineness, and uniformity of the raw materials to prevent excessively wet, sticky, or agglomerated materials from entering the system, thus preventing material blockage, roller sticking, and poor pelleting. Precise and stable batching is crucial to ensure consistent raw material ratios and minimize pellet yield reduction caused by material fluctuations.
Fertilizer produciton machine status is key. The double roller press granualtor must ensure uniform roller pressure and reasonable gaps. Regularly check roller wear, hydraulic system pressure, and bearing lubrication. Auxiliary equipment such as crushers, mixers, screening machines, conveyors, and return systems must be synchronized to avoid blockages before extrusion. Start-up and shutdown of all equipment must follow standardized sequences to prevent stalling and overloading.

Process parameters must be stabilized and optimized. Adjusting the extrusion pressure, feeding speed, and screening particle size according to material characteristics ensures uniform granulation and moderate hardness, reduces the proportion of fine powder returned material, and improves the overall effective output of the line.

Standardized operation and on-site management are crucial. Operators must regularly inspect current, temperature, abnormal noise, and material blockage, addressing any anomalies promptly to prevent minor issues from escalating into shutdowns. Proper material flow is essential, ensuring the hopper is neither empty nor overflowing, and that returned material is promptly returned to its source for continuous production.

Daily maintenance and periodic upkeep are indispensable. Timely lubrication, tightening, and cleaning are necessary, along with timely replacement of wear parts to prevent excessive roller wear, bearing overheating, and seal failure.

Only with stable raw materials, intact equipment, a reasonable process, standardized operation, and proper maintenance can a roller extrusion granulation production line achieve minimal downtime, low losses, high granulation quality, high output, and long-term efficient and smooth operation.
