The drum granulator is a granulation equipment commonly used in the production of compound fertilizers, organic fertilizers, biological fertilizers, controlled-release fertilizers and other fertilizers. It is suitable for cold and hot granulation and large-scale production of high, medium and low concentration compound fertilizers. The main working mode of the drum granulator is wet granulation. Through a certain amount of water or steam, the basic fertilizer is fully chemically reacted after being humidified in the cylinder. Under certain liquid phase conditions, with the help of the rotating motion of the cylinder, the material particles are squeezed and agglomerated into balls by extrusion force.
The characteristics of the drum granulator are as follows:
1. The ball formation rate is 70%, the ball formation strength is high, there is a small amount of return material, the return material particle size is small, and it can be re-granulated;
2. Steam heating is introduced to increase the material temperature, so that the moisture content of the material after balling is low, and the drying efficiency is improved;
3. The drum granulator adopts a special rubber plate lining or acid-resistant stainless steel lining, which is corrosion-resistant and wear-resistant. At the same time, it realizes automatic scar removal and tumor removal, and eliminates the traditional scraper device.
Due to its unique advantages, drum granulators are widely used in various fertilizer production lines and are suitable for large-scale production of granular fertilizers.
