Advantages of granulating compound fertilizer on double roller granulator

The characteristics of the double roller granulator are destined to have a primary low position in the production of compound fertilizer. The advantages of the roller granulator in the compound fertilizer production technology are energy saving and consumption reduction. The extrusion granulation is to granulate the material at room temperature. Compared with other methods, it does not require monotonous methods such as fuel oil and gas. Because the monotonous process is omitted, the return ratio is low (accounting for about 15% of the total feed volume of the kneader), the technical process is simple, and the investment is low.

　　The double roller granulator has a wide range of applications. There are more than 20 kinds of materials for extrusion granulation: ammonium nitrate, urea, ammonium chloride, calcium nitrate, potassium chloride, potassium sulfate, etc. In addition, the use of extrusion fertilizer granulation machine can actively complete the conversion of commercial formulas in a very short time, and a set of equipment can produce products with more than 30 formulas.

　　 The double roller granulator does not require additional binders. The domestically used method for producing compound fertilizers is steam granulation. After the water vapor condenses and crystallizes between the material molecules, it acts as a binder during the manufacturing process. However, in the monotonous process, the water inside and outside the particles must be driven out, otherwise the fertilizer is easy to stick and agglomerate during the storage process. However, dry granulation does not need other additives, and only needs to use the intermolecular force of the material itself, which simplifies the process and reduces the energy consumption.
