Fertilizer granulators are core equipment in fertilizer production lines, and their operating efficiency directly determines overall production capacity. Improving efficiency is not simply about increasing speed; it requires a multi-dimensional approach involving raw material adaptation, parameter optimization, and maintenance support. The goal is to maximize production capacity while ensuring granule quality.

Raw material pretreatment: The moisture content of raw materials should be strictly controlled at 8%-12%. Excessive moisture can lead to sticking and clumping, increasing equipment load, while insufficient moisture makes molding difficult. Simultaneously, the materials should be crushed and screened to a particle size of ≤2mm and thoroughly mixed in a fertilizer mixer to prevent uneven composition, which can cause jamming or poor molding, thus clearing obstacles for efficient granulation.

Precise parameter matching: Based on the characteristics of the raw materials (hardness, specific gravity) and the target granule requirements, adjust the rotation speed, pressure, or inclination angle accordingly: lighter materials can have their speed increased to enhance propulsion, while high-hardness materials require increased pressure and reduced speed to ensure dense granules. Appropriate parameters can stabilize the granulation rate at over 90%, reducing rework losses and directly increasing production capacity per unit of time.

Daily maintenance: Regularly clean residual materials inside the machine, polish worn parts (such as roller surfaces and the inner wall of the disc), and check the transmission and lubrication systems to avoid sudden breakdowns and downtime. Also, match the granulator's capacity with the preceding and subsequent processes to prevent material accumulation or insufficient supply, thus avoiding efficiency waste.

In summary, improving efficiency requires a comprehensive approach considering raw materials, parameters, and maintenance, forming a closed loop. This allows the equipment to perform at its best while ensuring stable granule quality.
