Since 2005,we have built more than 300 sets of potassium sulfate kiins while constantly refining our masonry and production techniques. Recent breakthroughs in energy saving and combustion control have greatly improved our equipment's efficiency and safety. We possess deep professional accumulation and a strong technological heritage in this specialized field.
Our Business Scope includes:
.Potassium Sulfate EPC Projects
.SOP Kiln and Furnace Construction
.Auxiliary & Matching Equipment for SOP Furnaces
.Manufacturing and Sales of Spare Parts
.Kiln and Furnace Maintenance Services
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.
Distinctive Advantages Compared with Foreign Counterparts:
.Lower Capital Investment (CapEx)
.Short Factory Construction Cycle (4-6 Months)
.High Level of Automation
.Stable Equipment Operation
.High Thermal Efficiency
.Outstanding Operational Flexibility
.Exceptional Product Yield
.Proven & Reliable Quality
.Superior Eco-friendly Performance
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.).
