Double Roller Press Granulator: A Revolutionary Force in Fertilizer Forming?

In the field of fertilizer granulation technology, the double roller press granulator stands out with its unique forming principle. This equipment uses two counter-rotating rollers to directly compress powdered raw materials into dense granules under high pressure. This dry granulation process requires no binders or drying stages, bringing revolutionary changes to fertilizer production.
The core advantage of the double roller press granulator lies in its exceptional forming capability. When raw materials enter the compression zone between the two rollers, they undergo pressure reaching tens of tons, instantly compacting the powder into pre-designed shaped granules. This physical forming method not only preserves the chemical characteristics of the raw materials but also ensures granule uniformity and strength.
Within a complete fertilizer production system, the double roller press granulator perfectly coordinates with other fertilizer equipment. Front-end cage crusher ensure uniform raw material particle size, pre-conditioners adjust material moisture, and vertical disc mixer achieve thorough blending of formulated ingredients. Back-end screening equipment separates qualified products, coating machines enhance product performance, and packaging machines complete the final process. Each link has been carefully designed to ensure a smooth and efficient production process.
Compared to traditional granulation equipment, the double roller press granulator demonstrates multiple advantages. Its dry production process eliminates the drying stage, significantly reducing energy consumption; no need for binders ensures product purity; compact design saves floor space; more importantly, it can process various difficult-to-granulate materials, including high-concentration compound fertilizers, organic-inorganic compound fertilizers, and other special formulations.
Modern double roller press granulators continue to breakthrough in technological innovation. Hydraulic systems
