rotary drum granulator

Description of the Rotary Drum Granulator:
This rotary drum granulator is the key equipment in compound fertilizer industry. And it can be used in cold and heat granulation as well as large-scale production of compound fertilizers, which is of high, medium, or low concentration.
This granulator can be used in conjunction with other fertilizer equipment, or used individually.

Features of the Rotary Drum Granulator:
1.The barrel body of this rotary drum granulator is made up of special rubber plate lining or acid-resistant stainless steel lining plate, thus automatic scar and burl removal is achieved. So the traditional scraper device is canceled in this rotary drum granulator.
 

2.This granulator features an attractive appearance, rational structure, high granulating intensity, good corrosive resistance, good abrasive resistance, low energy consumption, long service life, convenient operation and easy maintenance, etc.
3.This granulator is applicable to producing both of organic and inorganic fertilizers.

Working Principles of the Rotary Drum Granulator:
Raw materials to be granulated can be steam, gaseous ammonia, phosphoric acid, ammoniacal solution, ammonium phosphate slurry, and triple superphosphate slurry. After these solid fertilizer particles enter into the rotary drum, they will make reciprocating movement under functions of gravity, centrifugal force, and friction force between fertilizers. With the rotary movement of the drum, produced materials spray onto the surface of granulation nucleus. Then the coating layers become thicker and thicker until produced materials are granulated into required dimensions. Finally, those obtained products are spilled out from the discharging hole.
