Construction of Sulfur Coated Urea (SCU) Production Unit

in which urea acts as a nitrogen source and sulfur acts as a coating and S.C.U. Urea fertilizer with sulfur coating ( With the commercial name of Hefaz, it regulates the release of nitrogen. The reason that sulfur has been used as a coating is that it is cheap and secondly, sulfur itself is a nutrient. Especially in Iran, where more than ninety percent of soils are limestone, it causes an increase in soil quality.

  To produce this substance, urea granules are passed through a stream of sulfur melt. Sulfur coating prevents water pollution compatible with the environment.  Sulfur coating is very brittle SCU It is buried underground and causes excessive consumption of fertilizer. Sulfur may be damaged while moving. For this reason, in the production process, other materials are also added to strengthen the breaking structure of sulfur and also cover the places that are not covered.
