15-20N. It is higher than the pellets hardness from pan pelletizer and drum granulator. Hence, this kind of compound fertilizer granule is more convenient for transport, storage and use. Because it has characteristics of lower pulverization rate and less NPK nutrient loss.

Do the moisture of final double roller granulation products meet the international requirements?

Of course. There are two reasons. For one thing, the moisture of raw materials for double roller granulation is about 5-10% (the best is 5%). For another, as mentioned above, roller extrusion pelleting process adopts dry granulation method, which means that there is no water involved.
