Double roller granulator is a new high-tech product developed by many years of experience in compound fertilizer processing equipment design and production. It is used for granulation of various organic matters after fermentation, breaking through the conventional granulation process of organic matters. Before granulation, the raw materials need not be dried and crushed, and the spherical particles can be processed by direct batching, which can save a lot of energy.
The advantages and disadvantages of fertilizer production by double roller granulator are as follows:

1. 1. The double roller granulator does not need to heat and humidify the materials, which can save investment and energy, and can also adapt to granulation containing heat sensitive materials such as ammonium bicarbonate and some organic fertilizers;
2.  
3. 2. In the production process, there is no waste water or waste gas discharged, which will not pollute the environment;
4.  
5. 3. The process flow of the fertilizer granulation machine is short and easy to operate, which is convenient to realize the production automation control and improve the production efficiency;
6.  
7. 4. There are no special requirements for the properties and particle size distribution of raw materials, so the source of raw materials is wide;
8.  
9. 5. The production is more flexible, and the product scheme can be changed at any time, which is conducive to the small batch production of special fertilizer;
10.  
11. 6. The particle size distribution of the product is uniform, without segregation and agglomeration;
12.  
13. 7. The product shape of the double roller granulator is not as round as that produced by traditional methods such as drum granulation and slurry granulation; if chemical reaction occurs between the ingredients in the product particles, the particles may crack.
