We provide a full-chain one-stop EPC turnkey service spanning from pre-project planning to formal production launch, covering the construction demands of potassium sulfate production lines with annual capacities ranging from 10,000 to 200,000 metric tons.
From engineering design,equipment manufacturing,and installation,to production processing and product testing-our entire suite of technologies and complete equipment sets are independently developed and completed by Dongyin.We have forged successful partnerships with numerous domestic and international enterprises (Egypt,Laos,Indonesia,the Philippines,India,Brazil,Saudi Arabia,etc.).
After project kickoff, we first complete market demand research, process route selection and plant layout planning, and customize exclusive production solutions tailored to local raw material properties. We then independently carry out R&D and manufacturing of core equipment, as well as installation and commissioning of the entire production line. Meanwhile, we deliver full sets of mature production processes including the Mannheim method and organic matter calcination method, and build a supporting product quality inspection system, finally realizing one-click compliance and production launch of the production line.
All our EPC projects are assigned a dedicated engineer team for full-process follow-up. We provide 365-day on-site technical support after delivery, and have completed full-line implementation for over 50 fertilizer manufacturers worldwide. This helps clients cut the project construction cycle by 30%, and enables stable output of high-quality potassium sulfate products that meet both Chinese national standards and EU standards right after production launch.

Built upon dry-roasting SOP production technology, our core technical innovation lies in the optimized structure of the Mannheim furnace and its specialized auxiliary equipment. This newly developed SOP reaction furnace successfully resolves materials challenges-such as susceptibility to corrosion and poor wear resistance in high-temperature, strong-acid environments while seamlessly overcoming process engineering obstacles in continuous-feeding production.
