The performance of a double roller press granualtor is influenced by a combination of factors. The following is a detailed analysis:

1. Automation Level: The higher the degree of automation in modern double-roller extrusion granulators, the higher their efficiency. Organic fertilizer equipment equipped with intelligent control systems can monitor key parameters such as feed rate, roller pressure, temperature, and speed in real time, and automatically adjust operating conditions according to pre-set programs.

2. Material Characteristics: The physical and chemical properties of different materials vary significantly, and their impact on pelletizer efficiency also varies. For example, biomass feedstock with a high lignin content exhibits a certain degree of self-adhesion during extrusion, which facilitates molding. However, excessive lignin content increases the material's hardness and makes extrusion more difficult.

3. Feed Rate: A stable and appropriate feed rate ensures even distribution of the material between the rollers, ensuring consistent pressure on each pellet during extrusion, resulting in uniform strength.

4. Post-processing: The impact of post-processing on pellet strength cannot be ignored. Common post-processing processes include drying, cooling, and screening. The drying process removes moisture from the pellets, further improving their strength and stability.

In summary, the performance of a double-roll extrusion granulator is influenced by a combination of factors, including equipment, materials, and process. In actual production, a deep understanding of the interrelationships between these factors is essential to effectively control pellet strength and produce high-quality pellets that meet diverse application requirements.
