Fertiliser Blending, Granulation and Bagging

A blending plant sells a nutrient ratio in a bag, and the farmer who spreads it gets whatever separated on the way there, which is why segregation matters more in this industry than almost any other. This course works against segregation. Delegates work through nutrient content, straight materials and the calculation that turns a target ratio into a raw material recipe. Raw material properties are covered, particularly particle size distribution, since blending materials of different size guarantees separation in handling. Compatibility is addressed, including the combinations that cake, absorb moisture or react. Bulk blending operations follow across batch and continuous plants, with weighing accuracy and mixing time. Granulation is covered as the alternative that eliminates segregation, including drum and pan granulation, binder use, drying and screening. Coating and conditioning for storage are addressed. Bagging, weight control and moisture protection follow. Quality control and nutrient verification are covered. The course closes on storage, on caking and on farmer complaints.
