The use and characteristics of the drum granulator


The Rotary Drum Granulator is a molding machine that can manufacture Materials into specific shapes. Rotary Drum Granulator is one of the key equipment in the compound fertilizer industry. It is suitable for large-scale production of cold and hot granulation and high, medium and low concentration compound fertilizer. The main working mode is wet granulation of pellets. After a certain amount of water or steam is used to adjust the basic fertilizer in the cylinder, the chemical reaction is sufficient. Under certain liquid phase conditions, the rotating force of the cylinder is used to cause agglomeration of the material particles. Into the ball. Operating principle of drum granulator: The drum granulator is filled with steam, gaseous ammonia or phosphoric acid or nitrogen solution, phosphorus ammonia slurry and heavy calcium slurry to complete the chemical reaction and heating in the cylinder. Fertilization granulation process; or compound granulation process of compound fertilizer supplemented with a small amount of water. The granulation of the material through the rotation of the cylinder is carried out in the cylinder without rolling, rotating at a definite humidity and temperature to form a ball. Ball making process.

Features of the Rotary Drum Granulator:
1. The drum of the drum granulator adopts acid-resistant stainless steel lining, which realizes automatic removal of mites and tumors, eliminates the traditional device, eliminates the phenomenon of material sticking and reduces the labor intensity of workers.
2. The drum granulator is heated by steam to increase the temperature of the material to make the material flow after the ball is formed into a ball to improve the drying efficiency;
3. the drum granulator has a ball-forming rate of 70%, and a small amount of recycled material has a small particle size and can be re-granulated;
4. drum granulator has nice appearance, corrosion resistance, wear resistance, low energy consumption, long service life and convenient operation.
5. drum granulator production, large power consumption, low maintenance costs.
