- Unloading of raw materials from wagons or trucks and transferring into storage boxes.
- A preparation unit for raw materials (delumping, screening, crushing, drying).
- A weighing and mixing unit of the raw materials.
- A compaction unit transforming the powders into flakes.
- A granulation-screening unit converting the flakes into granules of the required calibrated range.
- And for some plants and in particular for the production of compacted fertilizers, a finishing unit with polishing and coating of granules for improving appearance (round shape), anticaking and reducing amount of residual fines with easier storage.
- Transferring of granules into storage boxes.
- Packing and pelletizing of finished products.
