Compound fertilizer double roller granulation process: automatic batching system → fertilizer crusher → fertilizer mixer machine
→ roller granulation unit → screening machine → packaging machine.
The advantages and disadvantages of compound fertilizer produced by double roller granulator
are as follows
a) In addition, it can save energy and energy for some materials, such as heating, heating, heating, etc.
b) The fertilizer granulation machine
has no waste water or waste gas discharged in the production process, and will not pollute the environment.
c) The process is short, the operation is simple, it is easy to realize the production automation control and improve the production efficiency.
d) There are no special requirements for the properties and particle size distribution of raw materials, so the sources of raw materials are wide.
e) 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.
f) The particle size distribution of the product is uniform, without segregation and agglomeration.
g) The shape of extrusion granulation product is not as round as drum granulation, slurry granulation and other traditional methods; if there is chemical reaction between the ingredients in the product particles, the particles may crack.
