The difference between rotary drum granulator and disc granulator

Rotary drum granulator and disc granulator are two kinds of granulation equipment, which are commonly used in fertilizer production industry. What is the difference between them?
The main advantage of the rotary drum granulator is to use steam to heat and adjust the humidity, which can reduce the granulation moisture and reduce the load of the dryer. The granulation rate of the strand-transformed granulator can reach 70%. The traditional scraper device is eliminated, and the phenomenon of material sticking to the wall is eliminated. However, if the process conditions are not well controlled, the return material will be higher than the disc granulator.

The disc granulator adopts an arc structure, and the granulation rate can reach more than 95%. The reducer and motor of the disc granulator are driven by a flexible belt, which can start smoothly and reduce the impact force. The advantages of the disc granulator are uniform granulation, less material return and large production capacity. But the dust and smoke pollution are serious.
The granulator is the key equipment in the fertilizer production line. It decides the shape of granules. There are different types of granulators for organic fertilizer and compound fertilizer. And different granulators can produce different shapes of pellets. Welcome to contact us for details.
