The double roller granulator is suitable for granulation of compound fertilizer, medicine, chemical industry, feed and other raw materials with high granulation rate.

Double roller granulation process: automatic batching system → fertilizer mixer machine → roller granulation unit → screening machine → packaging machine.


Production process of double roller granulator
1. Qualified raw materials are added to the mixer according to the ratio requirements and mixed evenly;
2. Transport to the disc feeder, and remove the ferrous material from the material during the transportation process;
3. The material in the disc feeder evenly enters the roller granulator, and the material is forced to pass between the two pressure rollers to be squeezed into flakes, and the flakes are broken into pieces by the coarse crusher under the pressure roller. Screening; the materials on the screen continue to be crushed and screened;
4. The semi-finished products are transported to the finished product screening machine; the fine particles after screening are directly returned to the disc feeder; the large particles are crushed by the crusher and then returned to the disc feeder.
5. The qualified products after screening are transported to the automatic packaging scale for weighing, packaging, and storage.

The double roller granulator is suitable for making soluble or non viscous particles, especially for chemical fertilizer particles. It is not suitable for granulating organic fertilizer with sticky rice husk and chicken manure with certain water content. It is easy to plug the die hole. It is necessary to clean the mold hole regularly, resulting in the consequence of not working continuously.
