Rotary Drum Granulator: The Core of High-Capacity Compound Fertilizer and Organic Fertilizer Granulation
Structure and Working Principle: The rotary drum granulator is the most common large-scale granulation equipment in compound fertilizer and organic fertilizer production lines. Its main body is a slightly inclined rotating cylinder with multiple lifting plates distributed along the circumference of the inner wall. During operation, material enters from the higher end of the cylinder. As the cylinder rotates, the material is lifted and thrown down by the lifting plates, forming a material curtain. Simultaneously, steam, water, or binder is evenly sprayed onto the tumbling material through spray pipes inside the cylinder, causing the fine particles to gradually adhere and agglomerate into spheres.
