Production line process of npk compound fertilizer produced by double roller granulator
The npk compound fertilizer double roller granulator has no drying process. It is granulated at room temperature and formed at one time. It has low investment, quick results and good economic benefits. The npk compound fertilizer double-roll granulator has low power, reliable operation, no three wastes, stable operation, convenient maintenance, reasonable flow layout, advanced technology, and low production cost.
Brief introduction to the production process of npk compound fertilizer by double roller granulator
1. Add qualified raw materials to the mixer and mix evenly
2. It is transported to the disc feeder, and the ferrous substances in the material are removed during the transportation process.
3. The material in the disc feeding bar is uniformly fed into the lambda extrusion granulation bar. The material is forced to pass between the two pressure rollers and is squeezed into thin slices. The thin slices are broken into pieces by the coarse crushed bar 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 pulverizer 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.
