For steel belt granulation equipment, if it can produce spherical particles, would it have better application prospects?

During this period, I learned some basic knowledge about steel-band granulation for compound fertilizers. It is said that many fertilizer manufacturers in China have tried to use this method of granulation, but without success. The reason is that the particles produced by belt granulation are hemispherical in shape, and they do not have as attractive an appearance as those from tower granulation. If technical improvements enable belt-type granulation equipment to produce spherical particles similar to those made by high-tower granulators, then does belt-type granulation have a future in the fertilizer industry?
The principle of steel strip granulation determines that spherical shapes cannot be formed.
According to the current principles, it is impossible to create a spherical shape. But we have developed a technology that, through the use of additives and surface treatment, allows molten slurry droplets to automatically shrink into spherical shapes on specific surfaces, just like mercury; and after cooling, they remain spherical without sticking to the surfaces they come into contact with. We would like to try applying this technology in combination with steel belt granulation.
