As a Chinese foreign trade company specializing in fertilizer equipment, our double-roller extrusion granulator features “multi-material compatibility, additive-free forming, and energy-saving drying.” It can flexibly produce organic and inorganic fertilizers, as well as de-icing agents. Sold to 45 countries and regions across Southeast Asia, Europe, and the Middle East, it helps fertilizer and chemical plants worldwide address the pain points of “granulation requires adhesives, high drying energy consumption, and limited material compatibility.” This provides a “Made in China” solution for green, low-cost production.

The equipment’s core advantage focuses on “additive-free production in multiple scenarios.” It utilizes a high-strength alloy roller design and an extrusion molding process, eliminating the need for any adhesives. Granulation relies solely on the physical properties of the raw materials, eliminating chemical residues. For organic fertilizer production, it can transform fermented livestock and poultry manure and straw powder into 2-8mm granules with a molding rate exceeding 92%. For inorganic fertilizer production, it can process mixed raw materials such as urea and diammonium phosphate, ensuring nutrient loss. For de-icing agents, it can press raw materials such as calcium chloride and sodium chloride into pellets to prevent clumping during transportation. It also eliminates the drying step required for traditional granulation, directly producing finished products with a moisture content of 10%-15%. This reduces energy consumption by 40% compared to drying-type equipment, significantly reducing production costs and carbon emissions.

The equipment is specifically optimized for different material characteristics. For organic fertilizer production, corrosion resistance is emphasized, with contact parts made of 304 stainless steel to resist humic acid attack. For inorganic fertilizer production, wear resistance is emphasized, with the roller surfaces hardened (hardness exceeding HRC60), ensuring a service life exceeding 5,000 hours. For de-icing agent production, the machine body is equipped with an anti-corrosion coating to prevent raw material corrosion. The unit has an hourly capacity of 1-8 tons and a daily capacity of 24-192 tons, making it suitable for both small and medium-sized workshops and large-scale factories. It supports a wide range of voltage options, including 110V, 220V, and 380V, and operates stably in the high-temperature and high-humidity environments of Southeast Asia, the dry and dusty conditions of the Middle East, and the low temperatures of Europe.

Easy to operate and maintain, the machine features a bilingual Chinese and English touch panel with preset parameters for over 8 different processes, including “organic fertilizer granulation,” “compound fertilizer granulation,” and “de-icing agent forming.” Workers can master the process after just one hour of training. Its modular design allows for the removal and replacement of rollers and transmission components. Daily maintenance requires only regular cleaning of roller surfaces and checking pressure parameters. Complying with international standards such as EU EC 1935/2004 (fertilizers) and EN 12625 (de-icing agents), it easily passes global market quality inspections.

Currently, this equipment has enabled an Indian fertilizer plant to achieve dual production of organic and compound fertilizers, reducing costs by 35%. A German chemical company is using it to produce environmentally friendly de-icing agents, securing EU market access. A Brazilian farm is using this equipment to produce its own organic fertilizer, increasing fertilizer utilization by 20%. Choosing our roller extrusion granulator offers a one-stop solution for diverse production needs, balancing environmental performance and efficiency, making it a reliable partner for expanding into global markets. Customized roller dimensions and upgraded automatic feeding systems will be available in the future to further meet individual needs.
