Compaction granulation is an immensely effective, cost-efficient agglomeration option for potash and other salts, and it is an ideal method used to turn potash fines into a usable fertilizer product.
Compaction granulation operates under the principle that under extreme pressure, some materials will adhere to themselves without the addition of a binder. Here’s how the process works: material fines are fed between two counter rotating rolls, and the rolls use pressure to unite the fines into the desired form. This form is then broken up into the specified granule size.
Because this process relies on pressure, binder is not often needed. And without the addition of binder, no drying step is necessary either. This fact alone makes compaction an attractive option, as no binder and drying are a cost effective endeavor.
