June 24, 2026, Laiyang, Shandong , a “4‑unit roller extrusion granulator production line” meticulously crafted by Zhengzhou Huaqiang Heavy Industry Technology Co., Ltd. was officially delivered to the customer in Laiyang, Shandong, and put into trial operation. As another masterpiece of Huaqiang Heavy Industry’s deep cultivation of the Shandong market, this project provides a closed‑loop solution, from equipment customization to technical guidance, to meet the transformation needs of local fertilizer companies.

The biggest technological highlight of the Laiyang project lies in the matrix layout of the “4 roller granulators.” This equipment, a star product among Huaqiang Heavy Industry’s more than 40 mature fertilizer machinery products, mainly utilizes the extrusion principle to shape materials. Compared to traditional steam granulation, this process eliminates the need for drying, allowing for one‑time extrusion molding at room temperature. This not only greatly protects the bioactive components in the fertilizer but also reduces the energy consumption of the entire production line by approximately 40%. By operating four machines in parallel, the plant achieves flexible capacity allocation, capable of meeting both large‑scale centralized production orders and customized single‑machine production based on market demand.
At the heart of this extrusion granulation production line lies the advanced double roller press granulator – a robust roller extrusion granulator that applies high mechanical pressure to dry powder materials, forming dense, high‑strength granules without the need for binders or drying. This dry‑process technology is a key component of the npk fertilizer roller press granulator production process, which is particularly suitable for heat‑sensitive and high‑concentration formulations. By integrating four units in parallel, the line achieves exceptional flexibility and throughput, while the entire system – from feeding to packaging – is orchestrated by Huaqiang's proprietary control software, embodying the latest npk fertilizer manufacturing technology. Every npk compound fertilizer machine in the train is designed for precision, durability, and energy efficiency, ensuring that the final granules meet the highest quality standards for both domestic and export markets.
Precision Process: From Laboratory Data to Production Line Customization
In the early stages of the project, Huaqiang Heavy Industry's in‑house R&D team conducted multiple molding experiments on various raw material components provided by the Laiyang customer. Targeting the customer's specific material hardness and moisture content, technicians adjusted the extrusion ratio and speed of the rollers to ensure that the hardness and color of the finished granules met industry export standards. Furthermore, the production line integrates a fully automated packaging and palletizing system, significantly improving the collaborative efficiency of subsequent processes.
Benchmark Demonstration: 21 Years of Craftsmanship Supporting Green Agriculture
Since its establishment in 2005, Huaqiang Heavy Industry has implemented over 1,000 projects globally. The successful delivery of the Laiyang project further confirms Huaqiang Heavy Industry's core competitive advantage in fully automated organic fertilizer production lines. As a national high‑tech enterprise, Huaqiang Heavy Industry has always adhered to the mission of "empowering green agriculture with innovative technology." It not only provides customers with patented technology support but also ensures that equipment maintains efficient operation throughout its entire lifecycle through full‑cycle on‑site maintenance services.
With the official commissioning of the Laiyang production line, Huaqiang Heavy Industry will continue to leverage its professional customization capabilities and strict quality control system to help more agricultural enterprises balance economic value and environmental benefits, jointly promoting the sustainable development of global agriculture.
