Though not always needed, a cooling step in potash processing is often utilized after the drying stage. Cooling the material offers many benefits to the end-product, as well as to the processing operation, such as:
Increased efficiency: adding a potash cooler means the agglomerated product can be immediately bagged, handled, or stored after processing.
Reduced storage issues: cooling the material prior to bagging prevents caking and sticking during storage.
Enhanced agglomerates: cooling potash creates a more robust and resilient end-product, that is, agglomerates that are less likely to succumb to attrition.
Cooling potash can be carried out in a rotary cooler. Rotary coolers are prized for their high throughput, heavy-duty build, and ability to accept a variability in feedstock conditions.
