In small-scale organic fertilizer production lines, the organic fertilizer granulator is an important equipment for turning fermented organic materials into regular shaped particles. It not only improves the appearance attractiveness of organic fertilizers, but also facilitates packaging, transportation, and application. According to different working principles and technical characteristics, there are several types of organic fertilizer granulators on the market, which are very suitable for small production lines. Here are several commonly used models:

1. Disc granulator

Principle: The material is fed into a tilted rotating disk, and by the action of centrifugal force, the material is agglomerated and then rolled into spherical particles.

Advantages: Simple structure and easy maintenance; High granulation efficiency, suitable for mass production.

Applicable scenarios: Suitable for materials with strong viscosity, such as organic fertilizers that have been appropriately humidified.

2. Roller extrusion granulator

Principle: The material is compressed into pieces by two relatively rotating rollers, and then crushed into the desired particle size.

Advantages: High granulation strength, wear resistance, suitable for granulation of hard materials.

Applicable scenarios: Suitable for processing materials with certain hardness and compression resistance, such as biomass fuel particles and fertilizer particles.

3. Flat die extrusion granulator

Principle: The material is forced into the mold pores, extruded through the mold pores under high pressure, and forms particles after cooling and solidification.

Advantages: Compact structure, small footprint, easy operation, especially suitable for small production lines.

Applicable scenarios: Widely used in pellet production in various industries such as organic fertilizers, biomass fuels, and feed.

4. New type of organic fertilizer specialized granulator

Principle: Combining stirring, heating, and granulation, the material is softened and shaped by the heat generated by high-speed stirring and friction.

Advantages: One time granulation, no need for drying, energy-saving and efficient.

Applicable scenarios: Designed specifically for organic fertilizers, especially suitable for handling high moisture materials, reducing energy consumption during subsequent drying.

Choose Suggestions

When selecting an organic fertilizer granulator for a small-scale organic fertilizer production line, comprehensive consideration should be given to factors such as the characteristics of the raw materials, production scale, budget, and demand for particle morphology. Usually, disc granulators are a common choice for small-scale organic fertilizer production lines due to their simple operation and low cost. But for manufacturers who hope to further enhance product added value, pursue particle strength and aesthetics, they may prefer to use flat die extrusion granulators or new organic fertilizer specific granulators. Regardless of the type, it should be ensured that the equipment has good durability and stability to serve production operations efficiently in the long term.
