The process flow of using a rotary drum granulator to process organic fertilizer from livestock and poultry manure is as follows:

1. Raw material pretreatment:

Collection and crushing: After collecting livestock and poultry manure, it is crushed into granules or powders suitable for granulation through crushing equipment.

Mixing and blending: Mix with other organic substances (such as straw, humus soil, etc.), adjust the moisture and nutrient composition, and ensure the appropriate fertilizer ratio.

2. Drum granulation:

Rotary drum granulation: The mixed materials are fed into a rotary drum granulator, and the materials collide and rub against each other during the rotation process, gradually forming particles.

Add binder: Add an appropriate amount of water or binder (such as starch, molasses, etc.) to help the material bond into particles and increase the strength of the particles.

3. Particle hardening and drying:

Hardening and drying: After being granulated by a rotary drum, the particles are usually wet and require drying equipment to reduce their moisture content, making them hard and suitable for storage and transportation.

4. Cooling and screening:

Cooling: Cool the hot particles to room temperature through a cooling machine to prevent moisture from affecting subsequent packaging.

Screening: Screen out unqualified particles (such as particles that are too large or too small) to ensure uniform particle size.

5. Packaging and Storage:

Packaging: Qualified organic fertilizer particles are packaged by automatic packaging equipment for easy sales and storage.

Storage: When storing, it is necessary to keep it dry to avoid moisture that may cause a decrease in fertilizer quality.

The rotary drum granulator mixes animal manure with other organic matter through the rotational friction inside the drum, and then goes through granulation, drying, cooling and other steps to produce granular organic fertilizer, which is convenient for use and storage.
