1. Transport the treated poultry manure (cattle, sheep, chicken manure, etc.) directly to the raw material mixer;
2. Transported to the drum granulator, and steam (or water) is introduced at the same time. The material forms a rolling material bed by the friction generated by the rotation of the drum granulator, and the extrusion force generated by rolling makes it contain a certain liquid phase. The materials agglomerate into small particles, these small particles become the core, and adhere to the surrounding powder to form qualified particles;
3. Transport to the organic fertilizer dryer for heat exchange with the heat from the hot blast stove;
4. Transported to the hot sieving to sort the particles, and the fine particles are directly returned to the drum granulator, as the core to continue to participate in the adhesion of the particles into balls;
5. The semi-finished product particles after screening are transported to the organic fertilizer cooler, and the fertilizer is cooled by natural cold air or strong cold air;
6. Transported to the finished product sieving machine, the large particles are crushed by the pulverizer and then returned to the drum granulator to continue to participate in the ball formation;
7. The qualified products after screening are transported to the coating machine for coating treatment;
8. Transport to a fully automatic packaging scale for weighing, packaging and warehousing;
9. Drying, cooling and workshop dust are discharged after being treated in three levels: cyclone dust collector, labyrinth dust removal room, and wet washing.
