Extrusion Granulation of Inorganic or Organic Fertilizer

Extrusion granulation does not require heating and humidification of the material, which both saving investment and energy, and it’s also adapting to the granulation of materials that containing heat-sensitive materials, such as ammonium bicarbonate and some other organic fertilizers. There is no waste water or gas discharge in the production process, so it will not pollute the environment. Extrusion granulation process is short, easy to operate, easy to achieve automation production control and improve production efficiency. Without special requirements to the nature and particle size distribution of the raw materials, so the raw materials are a wide range of sources.

Brief introduction of organic inorganic fertilizer extrusion granulation production line process:

1. According to the proportioning requirements, the qualified raw materials should be added into the high efficiency mixer and well mixed.
2. Transfer the mixed materials to the disc feeder, clean the iron content of the material during the delivery process.
3. The mixed material in the disc feeder flow into the roller extrusion granulator evenly, then forced to be pressed into thin slices by the two rollers under the disc feeder. Sieving the materials after the slices broken into pieces by the crusher under the rollers, and continually sieve the material on the screen mesh.
4. Transport the semi-finished products to the finished product sieving machine: the fine particles after screening are directly returned to the disk feeder; the large particles are crushed by the crusher and then returned to the disk feeder;
5. The qualified products after screening will be sent to the full automatic packing scale to weighing, packaging and warehousing.

Advantages of production of compound fertilizer by extrusion granulation process:

1. Extrusion granulation does not require heating and humidification of the material, which both saving investment and energy, and it’s also adapting to the granulation of materials that containing heat-sensitive materials, such as ammonium bicarbonate and some other organic fertilizers.
2. There is no waste water or gas discharge in the production process, so it will not pollute the environment.
3. Extrusion granulation process is short, easy to operate, easy to achieve automation production control and improve production efficiency.
4. Without special requirements to the nature and particle size distribution of the raw materials, so the raw materials are a wide range of sources.
5. Flexible production, and the product scheme can be changed at any time, which is good for producing special fertilizer in small batch production;
6. The product has uniform particle size distribution and no segregation or agglomeration;
7. The particle shape produced by extrusion granulation is not as round as that produced by traditional methods, such as rotary drum granulator. If there are chemical reactions between the ingredients in the product particle, it may lead to particle cracking.
