The production line is driven by an electric motor through belts and pulleys, transferring power to the main shaft, and synchronously working with the driven shaft through gears. After the material is added from the feeding hopper, it undergoes the extrusion action of the rollers, forming compact granules, and after subsequent processes such as screening and crushing, the final product of compound fertilizer granules is obtained.

The entire set of equipment includes an automatic batching machine, crusher, extrusion granulator, screening machine, automatic packaging scale, and conveyor, etc.
