Our advanced Potassium Sulfate Fertilizer Production Line utilizes the industry-leading Mannheim Process, offering a superior alternative to the traditional double decomposition method. By reacting potassium chloride with sulphuric acid at high temperatures (above 600ºC) within a specialized muffle furnace, our equipment ensures a complete chemical reaction, resulting in high-purity Potassium Sulfate (SOP) and high-quality hydrochloric acid byproduct.
Engineered for industrial efficiency and environmental compliance, our production line incorporates innovative flue designs for energy recovery and a sophisticated HCl absorption system. This integrated approach not only maximizes output and reduces coal consumption but also addresses environmental concerns through a dedicated waste recovery system, making it a sustainable choice for large-scale fertilizer manufacturing.
