fertilizer granulator Nov 7, 2023

The drum granulator uses low-humidity agglomeration granulation to increase the granulation temperature to increase the amount of liquid in the basic material, which promotes the material to form pellets at a lower water content. It has the advantages of easy drying, energy saving, and consumption reduction.
The drum granulator adopts a unique design: the material particles can directly collide with each other. With a wide range of applications and no special requirements for materials, it is widely used in large-scale organic fertilizer production lines and npk compound fertilizer production lines. In addition, it can directly produce organic fertilizer to eliminate the need for pre-drying and crushing. Spherical particles of particles. High granulation rate, drum organic fertilizer has a good appearance.

The granulation process of the drum granulator increases the temperature and viscosity of the material through the use of steam, so that the water content of the material can be reduced during the pelletizing process, thereby reducing the drying load, and the liquid phase distribution of steam is comparable to that of water Evenly. Only when the liquid phase of the material is insufficient and the material is unstable, add water as a supplementary means. During the production process, we have encountered improper installation of steam nozzles and uneven distribution of the liquid phase of the material, causing the material where there is more liquid phase to stick into large balls, and where the liquid phase is insufficient, the material is difficult to ball, which affects the formation of particles. In view of this situation, we can increase the steam nozzle to increase the steam receiving area of ​​the material.

Application of Drum Granulator in NPK Compound Fertilizer Production Line

fertilizer granulator Nov 7, 2023

The drum granulator is a method of mixing and granulating powdered basic fertilizers, and is widely used in the granulation of npk compound fertilizers. The principle of npk compound fertilizer drum granulator:
 The material forms a rolling material bed by the friction generated by the rotation of the drum granulator. The squeezing force generated by rolling makes the material containing a certain liquid phase agglomerate into small particles. These small particles become the core and adhere to the surrounding powder. Form larger particles. Since the drum granulator is generally inclined 1°~2.5° to the discharge end, the pellets slowly roll toward the discharge port while rotating with the cylinder. Qualified pellets leave the drum granulator and then enter the dryer for drying, and then go through screening, cooling, coating, packaging and storage. After being crushed, the on-screen material and the under-screen material are sent to the hopper as the return material and the basic fertilizer is granulated at the same time.

The function of the rotary drum npk fertilizer granulator is to pre-granulate the powdery material in the cylinder to form tiny particles with a diameter of 1 to 2 mm. The granulation effect of the drum granulator will directly affect the ball formation rate and product quality.
The drum npk fertilizer granulator effectively prevents the problem of a large amount of powder from flowing out with the granular material, reduces the processing volume and return volume of the subsequent drying, cooling, and screening equipment, and reduces the power consumption of the subsequent equipment. It has a good economic benefit.
The roller extrusion granulator is a key equipment for compound fertilizer granulation, with advanced technology, reasonable design, compact structure, novel and practical, low energy consumption, and matching with corresponding equipment to form a small production line, which can form a certain capacity of continuous and mechanized production. Adopting the eugenic formula, without drying, produced at room temperature, the product is rolled and formed in one go, ensuring that the product quality meets the technical requirements of compound fertilizers. It is an updated product for the production of high, medium, and low concentration specialized compound fertilizers for various crops and the energy-saving and consumption reduction of the compound fertilizer industry.
