Recently, JINDA Shengyuan group has independently developed and obtained the national invention patent technology (Patent No.: zl201610720769. X). The expansion project of the second production line of chelated potassium (potassium sulfate) has been successfully put into operation, with an annual output of 150000 tons. The successful expansion of this production line marks another great breakthrough in the production technology of chelated potassium (potassium sulfate) of the group, with an increasing degree of product production automation and more mature production technology. After expansion, the company's annual production capacity of chelated potassium (potassium sulfate) reaches more than 200000 tons, which can meet the production demand of 500000 tons of sulfur based compound fertilizer per year.

Since the chelated potassium (potassium sulfate) production line of JINDA Shengyuan group was put into operation, the sulfur based compound fertilizer products produced have uniform particles, high strength, stable nutrient indexes, good water solubility and obvious application effect. They are welcomed by dealers all over the country, and the products are in short supply. Therefore, in order to meet the market demand, the leaders of the group decided that Zhang Fenglin, deputy general manager and chief engineer in charge of the work of the group, led Li Huabin, director of equipment maintenance, Chang Yanlong, director of workshop, Liu Tiebing and others to form a research group to continuously solve various process problems through technological innovation, and after nearly a year of technological innovation and construction, Based on the original chelated potassium (potassium sulfate) technology, it was expanded again and successfully started at one time.

JINDA Shengyuan chelated potassium (potassium sulfate) project has no waste water, waste gas and dust emission, low raw material cost, no noise in the production process and no by-product hydrochloric acid. It is more energy-saving, consumption reduction and environmental protection than traditional Mannheim process and other dechlorination technologies. The potassium sulfate produced by Mannheim process uses more falling film absorbers to absorb hydrogen chloride, and hydrogen chloride will overflow to pollute the environment. However, the patented technology of chelated potassium (potassium sulfate) independently developed by the company does not generate hydrogen chloride, and the heat source comes from its own reaction heat, saving a lot of energy and money.

The successful expansion of chelated potassium (potassium sulfate) production line of the group has broken the industrial monopoly and solved the problem that northeast enterprises cannot independently produce potassium sulfate fertilizer. The product quality is stable and the production cost is low, which has attracted the attention of the same industry.
