INFLUENCE SOME GRANULATION PARAMETERS ON THE PROPERTIES OF NPK FERTILIZERS

Abstract

The use of granular compound fertilizers for plant fertilization is most rational. In this case, a balanced content and ratio of nitrogen (N), phosphorus (P) and potassium (K) is formed in each pellet. Powder granulation is a complicated process, which depends on many factors. Choosing the suitable process parameters is imperative for the quality of the product. The effect of some of the granulation parameters (chemical nature of filler, granulation temperature, moisture content, pH of irrigation solution) on 8–20–25 granular NPK fertilizer properties (granulometric composition, static strength of granules, bulk of density and the pH of 10% fertilizer solution) were examined. The optimum parameters of the granulation process in drier drum granulator conditions in laboratory were determined and high-quality 8–20–25 NPK fertilizers were produced.
