On the stage of agricultural and industrial production, the double roller press granulator stands out as an indispensable star equipment, thanks to its exquisite fertilizer granules compaction technology. This highly efficient organic fertilizer manufacturing machine transforms raw materials into invaluable pellets through a series of precise operations, injecting strong momentum into sustainable development.
The entire process begins with careful material preparation. Raw materials undergo pre-treatment such as crushing, mixing, and appropriate humidification to enhance their plasticity and flowability, laying a solid foundation for subsequent extrusion granulation. The pre-treated material is then evenly fed between two rotating pressure rollers through a feeding device, ensuring continuous and uniform distribution to maintain the stability of the granulation process.
When the material enters the narrow gap between the two rollers, high-pressure extrusion takes center stage. The rollers typically rotate in opposite directions, compacting and pushing the material forward under pressure. At this stage, the fertilizer compaction machine plays a critical role: the gaps between particles decrease, and the material is compacted into a sheet-like or strip-shaped structure with a certain thickness. This plastic deformation allows the material to maintain its shape under high pressure without immediate collapse.
The extruded sheet or strip material is then sent to a crushing device, such as a crushing drum or cutting blade, where it is broken into small pieces. These pieces are further reduced to particles of the desired size through mechanical force during subsequent screening and cooling processes. Finally, the formed particles are cooled to stabilize their structure, and unqualified particles are removed through screening to ensure uniform particle size in the final product.
The double roller press granulator is not only a perfect embodiment of technology but also a powerful engine driving a greener future.
