Pakistan's 4.0-type Extrusion Granulation Production Line Successfully Commences Operation

Recently, Zhengzhou Huaqiang Heavy Industry Technology Co., Ltd.'s customized 4.0-type extrusion granulation production line for its Pakistani client completed full-process installation and commissioning, officially entering the stage of large-scale production. This production line focuses on the high-efficiency granulation needs of compound fertilizers and organic fertilizers. Centered on a 4.0-type double-roller extrusion granulator, it integrates the entire chain of processes including feeding, conveying, screening, storage, and packaging. Coupled with a custom-designed steel structure plant layout, its stable operating performance, precise granulation effect, and adaptability to local production conditions have made it a benchmark project for China's high-end granulation equipment to empower South Asian agriculture. Production Line Full-Process Configuration and Core Equipment Analysis The entire production line follows a closed-loop process of "raw material pretreatment - precise granulation - grading and screening - finished product output." The equipment selection is professional, the layout is compact and orderly, and the connections between each unit are seamless, ensuring both production efficiency and strict product quality control, fully adapting to the raw material characteristics and production capacity requirements of Pakistan. Raw Material Conveying and Feeding Unit: Stable Supply Lays a Solid Foundation Raw Material Feeding and Lifting: The production line starts with a loader-loaded hopper. The hopper features a large-capacity, open design to accommodate the rapid loading of bulk raw materials. The feed inlet is equipped with a spill-proof buffer device to reduce material loss and dust. Raw materials are vertically conveyed to subsequent stages via a 315-type bucket elevator (10 meters). This elevator uses a plate chain drive structure, boasting strong load-bearing capacity, stable operation, and a conveying efficiency of 8 tons/hour. Its excellent sealing effectively prevents materials from becoming damp or contaminated during lifting, ensuring the purity of the raw materials. Precise Feed Control: The enhanced raw materials are conveyed to the granulation unit via a 16-type screw feeder. This feeder employs variable frequency speed control technology, allowing real-time adjustment of the feed rate based on the granulator's operating status (adjustment range 0.5-2 tons/hour). Combined with a material level monitoring sensor, precise control of the feed rate is achieved, preventing granulation quality fluctuations or equipment overload caused by uneven feeding, thus ensuring stable granulation.
