Dry and wet granulation technology for chemical fertilizer production
As a fertilizer granulator manufacturer, customers generally don’t know what kind of granulator they need when consulting us. The difference of fertilizer granulator is to select the appropriate granulation method according to the application requirements of materials. Zhengzhou Shengshi Machinery Co., Ltd. is here to introduce the method of fertilizer granulation and provide basis for customers to purchase fertilizer production equipment.

Fertilizer granulation equipment is just a general term. According to the fertilizer manufacturing process, it is mainly divided into wet method and dry method:
1. Wet granulation equipment: the main target material moisture content is more than 20%. There are many kinds of equipment and processing methods for wet granulation. For example: disc granulator, drum granulator, organic fertilizer granulator. This granulation method has continued. Through the application environment and processing requirements of different materials, the equipment has made great progress in continuous improvement.
For example, the particle size of organic fertilizer granulator is mostly between 1mm-6mm. Compared with wet granulation, dry granulation has the advantages of low energy consumption, environmental protection, no drying, no water and adhesive, and will not change the properties of materials; This is also the advantage of dry granulation different from wet granulation. Wet granulation equipment is more suitable for large-scale production of industrialized nitrogen, phosphorus and potassium fertilizer production line.
2. Dry granulation equipment: mainly refers to products with low moisture content. Generally, the water content below 10% is the zero boundary value. (very few materials can reach 16%, for example, some materials only contain crystal water). The particles produced by dry granulation are mostly irregular particles (such as common granular potassium fertilizer). The particle shape is generally similar to the shape of small gravel.
With the current industrial promotion and environmental protection requirements becoming more and more strict, many chemical and building materials powders need to form particles. Double roll extrusion granulator and flat molding granulator are commonly used in industry and agriculture.
