Compaction-Granulation
Thanks to its experience in the field of briquetting by roller press for more than 70 years,
This process allows the compression of volatile or voluminous powders between two rollers rotating in opposite directions, followed by a granulation step. The continuous strip of material produced by the compactor, called flakes, is in this case only an intermediate product from which the final product, called granules, is obtained by means of a second stage which is granulation and accompanied by a screen calibration.
This dry compaction-granulation process offers many advantages and is used in many applications such as for the production of fertilizers components (AS, KCI) and (NP, NK, PK, NPK) fertilizers.
Several fertilizer granulation techniques exist, either by wet, semi-wet or dry processes without the addition of binder. However, comparative tests between the different granulation methods have shown that the dry granulation process is clearly better than the wet and semi-wet granulation processes, particularly due to the drying equipment required for wet processes and the energy consumption required for their operation.
