Why does the drum-type compound fertilizer granulator produce rice-like grains?

The granulator is 1.5 meters in diameter and 8 meters in length; 40% of the particles produced have a size of 2.5 millimeters. What is the reason for this? I hope experts can offer some advice: QQ2037415663.15203578604
It is related to the rotation speed and rotation angle, as well as steam temperature and pressure
If it is special fertilizers such as compound fertilizers or slow-release fertilizers, the poster might consider fluidized bed granulation; this method results in particles with high strength, a narrow particle size distribution, a constant bulk density, and less dust. Further discussion can be held if needed
If the particles are formed in small sizes at once, it indicates good granulation performance; in such cases, the amount of sandy materials used in the formula can be increased.
Please consider the spraying effect of atomization and the amount of xanthan gum used as an auxiliary granulation binder.

Controlling the heat used in granulation is of utmost importance; insufficient heat leads to poor granulation quality； At the same time, it is necessary to control the feed ratio properly; small particles will gradually grow larger after passing through the granulator several times
