Complete Compound Fertilizer Production Line Featuring Double Roller Extrusion Granulator for High-Strength NPK, Ammonium Phosphate, and Potassium Fertilizer Granules

Product Introduction:

The double roller granulator compound fertilizer production line is a highly efficient and versatile solution designed to turn powdery chemical raw materials such as NPK, MAP, DAP, potassium chloride, and other fine powders into high-quality, uniform granules. Utilizing advanced dry roller press technology, this line compresses materials directly into granules without the need for adding water or using drying equipment, significantly reducing energy consumption, simplifying the production process, and lowering operational costs. The granule size is adjustable, typically ranging from 2 to 8 mm, allowing flexibility to meet different crop requirements and market demands. Built with wear-resistant and durable materials, the line ensures long-term stable operation and minimal downtime. Its compact design and flexible layout make it suitable for fertilizer plants of various scales, from small pilot setups to large industrial operations. Widely applied in agriculture, this production line enhances nutrient efficiency, improves crop yields, and supports sustainable farming practices. Additionally, it can produce specialty fertilizers, soil conditioners, and custom-formulated blends to meet specific regional soil and crop needs, making it a reliable, energy-saving, and cost-effective choice for modern fertilizer manufacturing.

Production Process:

01. Feeding: The raw materials are fed into the next stage, ensuring a steady and uniform supply that maintains the continuity of the production process.
02. Crushing: The raw material is crushed to reduce particle size, facilitating more efficient mixing and granulation.
03. Mixing: The crushed raw material is thoroughly blended with other additives to ensure a consistent and uniform formula.
04. Granulation: The mixed raw material is processed into Granules by a granulator.
05. Screening: The screening machine separates any oversized or undersized granules, ensuring uniformity in granule size.
06. Drying: The granules with high humidity are reduced by the dryer to improve the strength and stability of the granules.
07. Cooling: The dried granules are cooled to reduce their temperature and prevent them from deforming or sticking during storage and packaging.
08. Screening: Remove too large or too small granules through the screening machine to ensure uniform granule size.
09. Packageing: The qualified granules are packed according to the specifications for easy transportation and storage.
