Production of potash sulfate project, is my company a new technology of the success of scientific research personnel development research. Is the core of this technology in Germany dry roasting, on the basis of production of potassium sulfate, improved the structure of mannheim furnace and become a new type of reactor, combined with other specialized equipment, it has successfully solved the high temperature, strong acid problem of corrosion resistant materials, as well as the continuous production technology of feeding problems. Compared with similar foreign equipment, its outstanding characteristic is less investment, short build period (4 ~ 6 months), a high degree of automation, stable operation, high thermal efficiency, strong operability, high product yield, quality and reliable, good environmental protection effect. From engineering design, equipment manufacture, installation and production technology, product testing, complete sets of technology and equipment, all have the company independently to complete, and has set up a successful for home and abroad (Indonesia, the Philippines, India, Egypt, etc.) vendors are many sets of equipment and technology transfer, has achieved good effect.
Potassium sulfate contains both crops necessary potassium ion, also contain sulfur in promoting role for the growth of crops, is a kind of potassium and sulfur compound fertilizer, used for all crops, particularly applicable to avoid chlorine crops, such as tobacco, tea, sugar beet, melon, potato, peanuts, beans, vegetables and so on, can not only increase crop yield, but also can improve the quality of crop products. For example, can raise the flammability of tobacco, the sweetness of grapes and watermelon, potato starch and so on, with chlorine, phosphorus is reasonable use of 10-25% of the increase production effect can be obtained. Because of lower potassium sulfate index, use for a long time without destroying the soil structure, it will also no longer cause soil acidity and salinization.
