Rotary drum granulator is a kind of fertilizer units widely used in fertilizer industry. It can be used in combination with other fertilizer equipment or used individually.

Characteristics of Rotary Drum Granulator
1. Rotary drum granulator is applicable to cold granulating and heat granulating. It is suitable for large-scale production of fertilizers of high, medium and low concentrations.
2. Our rotary drum granulator adopts special rubber plate lining or acid resistant stainless steel lining plate. In our rotary drum granulator, the scar can be removed and the burl can be peeled automatically.
3. Features of our rotary drum granulator include an elegant appearance, rational structure, reliable quality, high pelletizing intensity, good corrosive resistance, good abrasive resistance, low power consumption, long service life, simple operation and easy maintenance, etc.
4. This fertilizer equipment can be used to produce organic fertilizers and inorganic fertilizers.

Granulating Mechanism of Rotary Drum Granulator
The raw materials for granulating are steam, gaseous ammonia, phosphoric acid or ammuniacal solution, ammonium phosphate slurry and triple superphosphate slurry. After these solid fertilizer powders enter the rotary drum, they will make reciprocating motion under the action of gravity, centrifugal force and friction force between fertilizers. With the rotary motion of drum, the generated materials spray onto the surface of granulation nucleus. The coating layer become thicker and thicker, and gradually the generated materials are granulated into desired sizes and discharged from the discharging hole.
