Drum granulation is mainly used for producing granular fertilizers such as compound fertilizers, compound fertilizers, organic fertilizers, and biological fertilizers. This process uses the rotating motion of the drum equipment to aggregate materials into balls inside the drum, forming uniform granular fertilizers. It has the advantages of high production efficiency, good particle strength, and flexible formula, and is widely used in the fertilizer industry.

Suitable fertilizer types for rotary drum granulation

Compound fertilizer

Drum granulation is one of the mainstream processes in the production of compound fertilizers, especially suitable for the production of binary or ternary compound fertilizers such as nitrogen, phosphorus, and potassium.

By adjusting the raw material ratio and process parameters, compound fertilizers with different nutrient contents and ratios can be produced.

Compound fertilizer

Suitable for large-scale production of high, medium, and low concentration compound fertilizers, it can flexibly adjust nutrient ratios to meet the needs of different crops.

Organic fertilizer and biological fertilizer

Can be used for granulation of organic waste (such as livestock manure, straw, etc.) to produce organic fertilizer or bio organic fertilizer.

By adding microbial agents, granular fertilizers with biological activity can be made.

Controlled release fertilizers and specialty fertilizers

It can be combined with coating technology to produce controlled-release fertilizers and extend their shelf life.

Customize specialized fertilizers according to crop needs, such as rice specific fertilizers, fruit tree specific fertilizers, etc.

Application advantages of rotary drum granulation

Reduce dust pollution: Granulated granular fertilizers have less dust, reducing environmental pollution.

Preventing compaction: Granular fertilizers are not easily compacted and are easy to store and use.

Slow release nutrients: The particle structure facilitates the slow release of nutrients and improves fertilizer utilization efficiency.

Convenient for mechanized fertilization: Granular fertilizers are suitable for mechanized application, improving fertilization efficiency.
