1. Raw material preparation: The step of organic fertilizer extrusion granulation is the preparation of raw materials. Usually, raw materials include organic waste such as feces, straw, and plant residues. According to the needs, the raw materials may need to be crushed and humidified first to ensure suitability for granulation.

2. Mixing and pretreatment: The raw materials are thoroughly mixed to ensure uniform distribution of each component. In this step, add an appropriate amount of moisture and adjust the humidity of the raw materials to achieve * * plasticity.

3. Extrusion granulation: After stirring and mixing, the raw materials enter the extrusion granulation equipment. Under the squeezing effect of the equipment, the material is compressed into uniform particles, ensuring the stable quality of fertilizer particles.

4. Cooling and screening: After particle formation, it needs to go through a cooling process to quickly cool it down and avoid the impact of excessive temperature on particle quality. After cooling, the particles will be screened by screening equipment to remove unqualified particles and ensure the quality and uniform particle size of the particles.

Qualified particles enter the packaging process, complete packaging, and prepare for shipment.
