Advanced Roller Press Granulator Compound Fertilizer Production Line with Dry Extrusion Technology for Urea, MAP, DAP, and Other Chemical Powders

Product Introduction:

Our double roller compound fertilizer production line is designed to turn chemical powders into high-quality fertilizer granules efficiently. Using dry extrusion technology, it presses materials directly into granules without adding water or using a dryer, which saves energy and simplifies the production process.

This line works with a wide range of raw materials, including NPK, MAP, DAP, potassium chloride, and potassium sulfate. The granules produced are uniform, dense, and strong, ensuring they remain intact during packaging, storage, and transportation.

With production capacities ranging from 1 to over 10 tons per hour, this line can be customized to fit small or large fertilizer plants. It is reliable, easy to operate, and helps you achieve stable, high-quality output at lower operational costs.

Features:

The double roller granulator compound fertilizer production line offers high granulation efficiency, producing uniform, dense, and strong granules for stable quality and better market acceptance.
Using dry roller press technology, it granulates powders directly without adding water or requiring drying equipment, making the process simple, clean, and efficient.
The granule size is flexible, adjustable from 2–8 mm to meet different crop needs and market demands, while its energy-saving design and durable, wear-resistant construction ensure low power consumption, minimal maintenance, long service life, and reliable performance.
Suitable for a wide range of powdery raw materials such as NPK, DAP, MAP, and potassium chloride, this production line is an economical and efficient solution 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.
