A Roller Extrusion + Drum Granulation Production Line in Turkey: Dual Granulation Technology Empowers Eurasian Agriculture!

In November 2025, Zhengzhou Huaqiang Heavy Industry Technology Co., Ltd. successfully completed the installation and commissioning of a roller extrusion + drum granulation composite production line tailored for a Turkish client, officially entering the stage of large-scale production. This production line innovatively integrates the dual core technologies of roller extrusion granulation and drum granulation, consolidating the entire chain from raw material pretreatment, precise batching, composite granulation, drying and cooling, coating and screening, to finished product packaging. With a robust configuration of 6 roller granulators + drum granulators, a highly automated process design, and quality standards adapted to the Eurasian market, it has become a benchmark project for Chinese high-end fertilizer equipment in overseas markets, providing Turkish fertilizer producers with a customized solution that combines flexibility and scalability. Production Line Configuration and Core Process Analysis The entire production line follows a closed-loop logic of "refined raw material pretreatment - precise batching and mixing - composite granulation - post-processing and finishing - standardized finished product output." The equipment layout is scientifically compact, with seamless connections between units. The synergistic application of dual granulation processes provides dual guarantees for product quality and production capacity, fully meeting the diverse fertilizer production needs of Turkey. Raw Material Pretreatment and Precision Batching Unit: Laying a Solid Foundation for Production Multi-dimensional Crushing Processing: The production line is equipped with four raw material bins, which can store nitrogen, phosphorus, and potassium main raw materials and mineral auxiliary materials respectively. The raw materials are transferred via a 7-meter belt conveyor to the dual crushing system—a cage crusher and a new type of roller crusher working in tandem. Cage crushers are used for coarse crushing of large raw materials, reducing particles ≤100mm in diameter to ≤20mm. The new roller crusher performs fine crushing, employing a high-strength, wear-resistant roller shaft design. Through the squeezing and shearing action between the rollers, the coarsely crushed raw materials are further pulverized to uniform particles ≤3mm, achieving a crushing efficiency of 8 tons/hour, meeting the stringent fineness requirements of various granulation processes. The crushing stage is equipped with a cyclone dust collector and induced draft fan, achieving a dust collection efficiency of 99% and a dust emission concentration ≤10mg/m³, complying with EU environmental standards. Precise batching and uniform mixing: The crushed raw materials are conveyed to a 5-bin batching machine via 9-meter and 7-meter belt conveyors. Each bin is equipped with a high-precision metering screw conveyor. Combined with a PLC intelligent control system, the feed rate of each raw material can be automatically adjusted according to the preset formula, with a batching error ≤0.8%, ensuring accurate fertilizer nutrient ratios. The batched materials are fed into a 40-type twin-shaft mixer via a 12-meter belt conveyor. The equipment employs an anti-rotating blade design with a wear-resistant coating on the blade surface. During mixing, the materials undergo strong convection, shearing, and tumbling motions, resulting in a mixing uniformity error of ≤2%, providing a homogeneous raw material foundation for the subsequent dual granulation process.
