Pressure agglomeration compaction methods for size enlargement of solid fertilizers

3 Pressure agglomeration (compaction) methods for size enlargement of solid fertilizers 

The following chapter will exclusively deal with the use of pressure agglomeration or compaction for the size enlargement of fertilizers because this is the modern and still little known alternative to conventional fertilizer granulation .

Its flexibility, due to the possibility of easily and quickly changing over and adapting the process to new product formulations. 

The economic operation of systems of any size, even with small capacities.
