Generally, the application of extrusion granulation method is to achieve the maximum production capacity, and the treatment of raw materials, pre-treatment and post-treatment of granulation also need to be carefully considered.

Typical granulation process: raw material treatment, pretreatment, granulation, post-treatment and granulation products Technical requirements of extruding granulator for organic fertilizer
1. Particle size. Fertilizer granulation machine extrusion granulation, the use of powder materials are generally made by crushing.
2. Heat sensitivity. Materials are sensitive to temperature, and show different properties at different temperatures.
3. Thixotropy.
4. Viscosity.
5. Liquidity. In the granulation process of fertilizer granulation machine, whether it is wet granulation or dry granulation, the materials used are required to have good fluidity.

The fertilizer granulators produced by Zhengzhou Huaqiang Heavy Industry Technology Co., Ltd. include organic fertilizer granulator, disc granulator, drum granulator, npk fertilizer granulator, double roller granulator, two in one organic fertilizer granulator, drum granulator, flat die pelleting machine, and ring die pelleting machine.
