The technology of organic fertilizer granulation machine is mainly used in the granulation of organic fertilizer production process, and it is suitable for the equipment of chemical industry, medicine, metallurgy, building materials and feed industry. It has the characteristics of compact structure, strong, convenient installation and use, and stable performance. According to different raw materials and the requirements of improving product quality and output, various organic fertilizer equipment manufacturers have developed various granulators, such as double roller granulator, drum granulator, disc granulator, new organic fertilizer granulator, flat die granulator, ring die granulator, etc. The following is the production process of organic fertilizer by disc granulation.

The advantages of disc granulation technology are simple equipment, low investment, easy operation and high granulation rate. The disadvantage is that the temperature required for granulation can not be guaranteed. The influencing factors in the process of disc granulation include the fineness of raw materials, physical and chemical properties of basic fertilizer, feeding position, adding method and position of binder, water content of semi-finished products, suitable and stable feeding amount, diameter, inclination angle and rotation speed of granulator, granulation temperature, reproduction and addition of returned materials, etc.
