Non drying fertilizer granulation technology is mainly used for products with low water content. Generally, moisture content below 10% is a critical value. (some materials can reach 16%, for example, some contain only crystal water). Some organic fertilizer manufacturing processes have low water content, no need to dry, and save energy.
The double roller granulator belongs to drying granulation equipment without drying process. It has high granulation density, good fertilizer efficiency and high organic content. The particles are flat and round, suitable for compound fertilizer.
Most of the particles produced by dry granulation are irregular particles (such as ordinary particle size potassium fertilizer), and their shape is similar to the shape of small gravel. The double roller granulator can produce all kinds of high, medium and low concentration NPK compound fertilizer and organic-inorganic compound fertilizer granulation, which meets the requirements of energy conservation and environmental protection.
Fertilizer granulation technology without drying extruder
The dry powder extruder consists of five parts: frame, head, pressure reducer, motor and crusher. It has the advantages of simple structure, high stability, convenient operation and maintenance, and strong adaptability of raw materials.
