WebThe concentration process furnishes urea "melt" for solids formation. Urea solids are produced from the urea melt by 2 basic methods: prilling and granulation. Prilling is a process by which solid particles are produced from molten urea. Molten urea is sprayed from the top of a prill tower. As the WebConical Prilling Tower Reclaimers. The discharge point to the downstream Conveyor is located at the center of the Prilling Tower base. The boom of the Reclaimer adjusts to the tower floor by adopting the same angle. This enables the urea prills to be conducted to this central point, discharging them to a downstream Conveyor by means of a chute.
