Extrusion granulation is the most commonly used granulation method in the fertilizer industry, which can produce high, medium and low content fertilizers.
The fertilizer granules produced by this granulation are cylindrical and can be rounded to achieve round granules. The selected raw materials are generally materials with low water content and poor viscosity.
Common raw materials are dung, furfural residue, humic acid, cassava residue, mushroom residue and other powdery organic materials with poor viscosity. Bio-organic fertilizer can be produced by adding biological bacteria before and after.
