The difference between disc granulator machine and rotary drum granulator?

2022/11/09

 Drum granulator and disc granulator are two types of granulation equipment commonly used in the fertilizer production industry. What is the difference between the two?
Rotary drum granulator is one of the main equipments in the fertilizer production industry, suitable for large-scale production of cold and hot granulation and high, medium and low concentration npk production line. The main working method is wet granulation of granules, through a certain amount of water or steam, the basic fertilizer will undergo sufficient chemical changes after being humidified in the cylinder. In a certain liquid phase environment, with the help of the rotary motion of the cylinder, the extrusion force between the material particles will agglomerate into balls.
The main advantage of the drum granulator is that the steam is heated to adjust the humidity, which increases the temperature of the granulated material, reduces the granulation moisture, reduces the load of the dryer, and improves the work efficiency. The granulation rate of the drum granulator can reach 70%, the equipment is simple to operate, the work flexibility is large, and the maintenance is convenient.

Disc granulator is one of the main equipment for npk fertilizer production line, organic fertilizer production process and organic and inorganic fertilizer granulation. The rounded corner of its organic fertilizer disc granulator adopts an overall arc structure, and the granulation rate can reach more than 95%. The organic fertilizer disc granulator has three discharge ports, which is convenient for intermittent production, reduces labor intensity and improves labor efficiency. The reducer and motor of the disc granulator are driven by soft belts, which can start stably, relieve the impact force, and improve the service life of the disc granulator equipment. The bottom of the organic fertilizer disc granulator is reinforced with multiple radiant steel plates, which are durable and never deformed. The organic fertilizer disc granulator is thicker and heavier, the base design is firm, and there is no need for anchor screws to fix it, and the operation is stable. The main gear of the compound fertilizer granulator adopts induction hardening, which doubles the service life. The granulation panel of compound fertilizer disc granulator is lined with high-strength glass fiber reinforced plastic, which is anti-corrosion and durable. It has the advantages of symmetrical granulation, high granulation rate, stable operation, durable equipment and long service life.
