Granular fertilizer production presents several kinds of problems. The caking phenomenon and moisture absorption are the critical ones that affect the physical quality of granules and make them unsuitable for their intended uses. Another frequent problem observed during granular fertilizers manufacturing, is the dust emission, which is generated during handling, storage and transport. The mechanical abrasion, chemical composition and storage conditions can be defined as the direct sources of this problem. For these reasons, the formulation of anti-dust coating compositions, capable of reducing the dust emission of monoammonium phosphate fertilizer, is the main goal of this study. To assess the usefulness of our perception, we used two types of experimental designs. First, we started with a mixture screening design, to select, from a list of five anti-dust coating components those that would further reduce the dust emission of the fertilizer. The second step was the application of a mixture design to formulate anti-dust coating compositions based on three components chosen by the screening design as the most effective ones. The mixture design results show that we were able to formulate several anti-dust coating compositions capable of reducing the dust emission of fertilizer granules by up to 29%, which has significantly improved their physical qualities. © 2021 Elsevier B.V.
