Double Roller Press Granulator: The Revolution in Dry Fertilizer Production

In the field of fertilizer production, a seemingly simple yet highly innovative equipment – the double roller press granulator – is fundamentally changing how we manufacture fertilizers. Unlike traditional granulation technologies, this equipment utilizes a unique cold compression process to directly transform powdered raw materials into high-density granules without drying procedures, bringing unprecedented efficiency and energy-saving breakthroughs to the fertilizer industry.
The core appeal of the double roller press granulator lies in its sophisticated mechanical design. As two parallel installed press rollers rotate relative to each other, they forcibly compress materials into mold holes, forming uniform and dense granules under tremendous pressure. This dry granulation process not only eliminates the energy-intensive drying steps required in traditional methods but also maintains the chemical stability of materials, making it particularly suitable for producing heat-sensitive organic and bio-fertilizers.
Within a complete fertilizer production system, the double roller press granulator forms a perfect collaborative chain with other equipment. Crushers first process raw materials into powders of appropriate particle size, batching systems precisely control the proportions of various nutrients, vertical disc mixer ensure thorough and uniform blending of materials, then the double roller press granulator compresses these pre-processed materials into shape, with rotary screener machine and packaging machines completing the subsequent processing. This seamlessly connected production process ensures consistent and reliable fertilizer quality.
The advantages of double roller press technology are impressive. By eliminating the drying process, it can reduce energy consumption by over 30% while avoiding nutrient loss caused by heating. The produced granules possess higher mechanical strength, resist breakage during transportation and storage, and generate less dust
