In addition,NPK compound fertilizer often has more premium space than single fertilizer,so many manufacturers have incorporated NPK compound fertilizer often has more premium space than single fertilizer,so many manufacturers have incorporated NPK compound fertilizer into their product portfolio.
The common granulation processes of compound fertilizer include rotary drum granulation,disc granulation,spray granulation,tower granulation etc.
High concentration nitro compound fertilizer was produced by higher tower melt rotating granulation.This technology is to spray the melt of nitourea,phosphorus and potassium from the top of the granulation tower,cool down and agglomerate into particles in the process of falling in the tower,which is also called melting granulation.In the ammonium nitrate production enterprise,using the high tower melting granulation method to produce compound fertilizer has the following advantages :
Firstly,it can directly use the concentrated solution of ammonium nitrate and the crushing of the solid ammonium nitrate to produce compound fertilizer.The operation simplifies the production process and ensures the production safety.
Secondly,the melt rotary granulation process makes full use of the heat energy of the concentrated solution of ammonium nitrate.The moisture content of the material is very low,and no drrying process is required which greatly saves engery consumption.
