Product description
Drum granulator is also called drum granulator and drum granulator. It is one of the key equipments in the compound fertilizer production industry. It is suitable for cold and hot granulation and large-scale production of high and medium concentration compound fertilizers. The granulation method of this equipment is mainly agglomeration wet granulation, that is, through a certain amount of water or steam, the basic fertilizer is bonded after the humidity is adjusted in the barrel. With the help of the force generated by the rotation of the barrel, the powdery fertilizer is formed The extrusion force aggregates into fertilizer granules.
Equipment advantage
1. High work efficiency: the lining is made of rubber engineering plastics, the material is not easy to stick to the cylinder, and the output is large.
2. High granulation rate: there is a small amount of returned material, and the returned material has a small particle size, which can be re-granulated to save costs.
3. Round shape: With the help of the rotating movement of the cylinder, the extrusion force between the material particles is reunited into balls.
4. Low moisture in the finished product: heating the material by steam to increase the temperature of the material, so that the moisture of the material after balling is low, and the drying efficiency is improved.
Working principle :
The main working mode of the rotary drum granulator is granulation wet granulation. Through a certain amount of water or steam, the basic fertilizer is fully chemically reacted after the humidity is adjusted in the cylinder. Under certain liquid phase conditions, the rotary motion of the cylinder is used to , so that the extrusion force between the material particles is agglomerated into balls. Materials are fed from the feed end, rotated through the cylinder, and made into granules under certain conditions, and finally flow out through the discharge port. Due to the continuous entry of materials and the continuous rotation of the granulator, mass production and granulation of fertilizers can be realized.
