A Industrial Prilling Tower is a vertical granulation system designed to convert molten materials into uniform spherical prills through controlled droplet formation and solidification. Molten feed is distributed at the top of the tower through a prilling head, forming droplets that fall under gravity. As the droplets descend, counter-current or co-current airflow cools and solidifies them into free-flowing spherical granules. The system ensures consistent prill size, high throughput, and efficient heat removal, making it suitable for large-scale continuous production.
Used For
