The Rotary Drum Granulator is a cornerstone piece of equipment used in the production of compound and organic fertilizers. It utilizes a wet granulation process, allowing base fertilizers to undergo a complete chemical reaction within the drum, where they agglomerate into spherical pellets. This machine is highly versatile, suitable for both cold and hot granulation, as well as the large-scale production of high, medium, and low-concentration compound fertilizers.
Key Features and Advantages:
High Efficiency & Quality: The Rotary Drum Granulator boasts a granulation rate of up to 70%. The resulting granules possess excellent structural strength, and the minimal “undersize” material (return feed) produced features a tiny particle size, making it very easy to re-granulate.
Thermal Optimization: By introducing steam to heat the materials within the Rotary Drum Granulator, the equipment effectively raises the temperature of the mixture. This process reduces the moisture content of the granules immediately after formation, significantly enhancing overall drying efficiency.
Advanced Lining Design: The interior of the Rotary Drum Granulator drum is fitted with specialized rubber sheets or acid-resistant stainless steel liners. These provide superior corrosion and wear resistance. Additionally, this design enables an automatic cleaning function (removing scars and buildup), eliminating the need for traditional manual scraper devices.
