NPK fertilizer production line of roller extrusion granulator

2020/09/09
NPK fertilizer production line of roller extrusion granulator is widely used in powder processing. It is characterized by no need to humidify or heat the material, and the material can be directly processed into particles. It can be used for organic and inorganic fertilizer granules, as well as for the processing of feed granules.
NPK fertilizer production line adopts dry extrusion granulation process. There is no waste water, no waste gas emission and no environmental pollution. Extrusion granulation process is short, easy to operate, easy to realize automatic production control, and improve the production efficiency. There are no special requirements for the properties and particle size distribution of raw materials, so the sources of raw materials are relatively wide.

1. According to the proportion requirements, add qualified raw materials into the mixer and mix them evenly.
2. Transfer to the disc feeder and remove metal material from the material during transmission.
3. The materials in the disc feeder evenly enter the extrusion fertilizer granulator machine. The material is forced to pass between two pressure rollers and is pressed into thin sheets. The flakes are broken into pieces by the coarse crusher under the action of the pressure roller. Sieving. The sieve material continues to be crushed and sieved.
4. Transport the semi-finished products to the finished product screening machine. The screened fine particles are directly returned to the disc feeder. The large particles are crushed by the mill and then returned to the disc feeder.
5. The screened qualified products will be transported to the automatic packaging scale for weighing, packaging and storage.
