Advantages and disadvantages of fertilizer production by extrusion granulator
1. The extrusion granulator does not need to heat and humidify the material, which saves investment and energy
2. There is no waste water or waste gas discharged in the production process, which will not pollute the environment;
3. The extrusion granulation process is short and easy to realize automatic control;
4. There are no special requirements for the properties and particle size distribution of raw materials, so the sources of raw materials are wide;
5. The production is flexible, and the product scheme can be changed at any time, which is conducive to small batch production of special fertilizer;
6. The particle size distribution of the product is uniform, without segregation and caking;
7. The shape of extrusion granulation product is not as round as that produced by drum granulation, slurry granulation and other traditional methods; if chemical reaction occurs between ingredients in product particles, it may lead to particle disintegration.
