What are the commonly used granulation equipment for fertilizer production?

Disc granulator: The raw powder is uniformly wetted by atomized water in the twin-shaft mixer to form a ball core with a very uniform particle size, and then sent to the ball forming disc to form a ball. The tilt angle of the pan can be adjusted to control particle size. The disadvantage is that the dust is large and the particle strength is small. High moisture (close to 50% to 60%). Therefore, drying must be configured to enhance the hardness of the particles. The disc granulator can be used in both organic fertilizer production process and npk fertilizer production line.
