In the world of double roller press granulators, powdered raw materials are perfectly formed through mechanical pressure alone, without the addition of any binders. This innovative dry granulation technology, with its outstanding environmental performance and economic benefits, is quietly revolutionizing fertilizer production.
The double roller press granulator uses two precisely matched rollers, exerting pressures of up to 50-200 MPa, to plastically deform the powdered material, forming a dense flake. Subsequently, crushing and sizing processes are performed to obtain the desired granular product.The entire process requires no water, eliminating energy consumption in the drying process.
The double roller press granulator is suitable for a variety of materials, including organic fertilizers, compound fertilizers, and microbial fertilizers. It is particularly well-suited for granulating heat-sensitive raw materials, preserving their biological activity.
Dry Granulation Production Process
Raw Material Pretreatment
Crushing, screening, and drying, equipped with a high-efficiency crusher and vibration screener machine, ensure uniform raw material particle size and provide ideal material conditions for extrusion granulation.
Precise Batching
Automatic weighing system and multi-bin batching system achieve an accuracy of ±0.5%. Recipe data is stored in the cloud to ensure consistent product quality.
Efficient Mixing The double axis mixer, with its double-helix design, achieves high mixing uniformity and low residue, ensuring thorough and even mixing of all raw materials.
Roller extrusion
High-pressure core forming
Particle crushing
Achieving the ideal particle size
Screening and packaging
Finished product grading
From raw materials to qualified granular fertilizer, these devices are connected in a seamless production line, transforming agricultural waste and difficult-to-use chemical raw materials that would otherwise be wasted into “energy packs” that nourish crops.
