In organic fertilizer and compound fertilizer production lines, the double roller press granulator produciton technology  is a non-drying, room-temperature forming process. To improve the overall line efficiency, the key lies in matching upstream and downstream processes, ensuring stable equipment operation, and minimizing downtime and rework.

First, optimize raw material pretreatment to ensure stable moisture content and fineness. Raw material moisture should be controlled between 8% and 15%. Too dry, and it will easily shed powder and fail to granulate; too wet, and it will stick to the rollers and slip. Raw materials need to be thoroughly mixed beforehand to prevent clumping and impurities from entering the main machine, preventing roller damage and pressure fluctuations, thus reducing material blockage and rework at the source and stabilizing the granulation qualification rate.

Second, stabilize the main fertilizer produciton machine's operating parameters, and rationally control hydraulic pressure, feeding speed, and roller speed. Insufficient pressure will lead to loose granules and a high powder content; uneven feeding will easily result in inconsistent granule size. Maintaining continuous and uniform feeding ensures stable main machine load and current, avoids frequent start-stop cycles, and increases effective working time.

Furthermore, proper equipment maintenance and management of vulnerable parts are essential. Regularly inspect roller wear, bearing lubrication, and the condition of seals. Roller wear directly reduces the forming rate; timely repair or replacement can prevent a decline in output. Strengthening lubrication and maintenance to reduce downtime is key to improving the efficiency of long-term continuous production.

Finally, automating control stabilizes parameters such as batching, feeding, and pressure, reducing human error. A closed-loop system encompassing raw materials, granulation, screening, and return material significantly increases overall production line output, reduces energy consumption and labor costs, and achieves efficient, stable, and continuous operation.
