The organic-inorganic compound fertilizer granulator can process harmlessly treated organic matter (including high-temperature compost) and inorganic fertilizers (mainly nitrogen, phosphorus, and potassium fertilizers) into granular fertilizers, achieving precise fertilizer control and improving nutrient utilization.

Production technology of organic and inorganic fertilizers

Organic and inorganic compound fertilizers are generally not recommended to use the bulk blending fertilizer processing method, because the organic materials can only exert their adsorption and slow-release functions on inorganic nutrients when the organic and inorganic nutrients are fully in contact. The quick-acting effect of inorganic nutrients and the stable release of organic nutrients can be more effectively coordinated.

Granulation method of organic-inorganic compound fertilizer

The production process of organic-inorganic compound fertilizer needs to be fully stirred and then a certain amount of adhesive and conditioner are added for granulation.

The granulation method can adopt the lower-cost granulation method and extrusion method. Next, I will introduce their granulation processes in detail.

Granulation method

The granulation method of organic and inorganic compound fertilizer is a common fertilizer granulation process. The wet granulation method is used to make powdered raw materials into granular fertilizers. Both the disc granulator and the drum granulator use the granulation process. Below I will introduce their process differences and characteristics to you respectively.

▶ Disc granulator

The disc granulator puts the organic and inorganic fertilizer raw materials into a rotating circular granulation disc and uses centrifugal force and friction to agglomerate and granulate the raw materials. By adjusting the inclination angle and rotation speed, spherical fertilizer particles of different specifications can be produced. The granulation rate of this equipment is as high as 95%, with simple operation and high efficiency.

▶ Drum granulator

The drum granulator uses a high-speed rotating drum for granulation. In the drum, the organic and inorganic fertilizer raw materials continuously collide, rub, and agglomerate under the action of high-speed rotation, and finally form spherical fertilizer particles with regular particle size. The drum granulator has a large output and high particle uniformity, and is often used in medium and large-scale fertilizer production.

Extrusion method

The organic-inorganic compound fertilizer extrusion granulation method adopts the dry granulation method, and forms granular fertilizer by mixing and extruding the raw materials.

▶ Double-roller extrusion granulator

The working principle of the double-roller extrusion granulator is to feed the pre-mixed organic and inorganic fertilizer raw materials into the granulator through the feeding system. The two rollers rotate, compress, and extrude the raw materials, and granulate under a certain pressure on the roller surface. By adjusting the roller distance and roller surface shape, fertilizer particles of different specifications and shapes can be obtained. In the organic-inorganic compound fertilizer extrusion method, the double-roller extrusion granulator has high granulation efficiency and granulation quality, can realize continuous production, and has strong adaptability to raw materials. It is suitable for fertilizer raw materials of different types and contents.

The fertilizer granules produced by the organic-inorganic compound fertilizer granulator are rich in nutrients, easy to absorb and utilize, and have a significant effect on improving crop yield and quality. Reasonable use of production technology can ensure product quality, improve production efficiency, and promote agricultural development.
