Flat die pelleting production line: characteristics and applications

As a highly efficient pelleting equipment, the flat die pelleting production line boasts a wide range of capacity adaptability and is applied in various fields including agriculture, energy, and chemicals. Its unique technological advantages have made it popular with manufacturers of all sizes worldwide. The following details its core features, application scope, and key selection and operation points to help global readers gain a comprehensive understanding of this equipment. Capacity performance is one of the core indicators of a flat die pelleting production line, with significant differences in output between different models and configurations. Generally, the hourly output range for mainstream equipment is 0.08 to 5 tons, while large-scale customized production lines can reach 8 to 20 tons. Specifically, small-scale equipment, such as the KP-150C model, has an hourly output of 0.08 to 0.3 tons, suitable for laboratory research and development or small-batch pilot production, with a power requirement of 5.5 to 11 kW; medium-sized equipment, such as the KP-400/500 model, has an hourly output of 0.4 to 2.5 tons, ideal for small and medium-sized farms and fertilizer plants, with a power requirement of 15 to 55 kW; large-scale equipment, such as the KP-600/800 model, has an hourly output of 2.5 to 5 tons, suitable for large-scale fertilizer and feed mills, with a power requirement of 55 to 75 kW; and extra-large customized lines are designed specifically for large-scale chemical and mineral granulation, with power reaching 90 to 200 kW or more. Key factors affecting capacity include material moisture content, with an optimal range of 15% to 25%, and a particle size preferably not exceeding 2 mm. The viscosity and hardness of the material, as well as the die aperture and roller pressure, also significantly affect output and granulation rate.
