Drum granulator becomes high-efficiency production equipment in compound fertilizer industry

Drum granulator is mainly a kind of fertilizer granulator machine. After steam, basic fertilizer plus phosphoric acid or nitrogen solution, phosphorous ammonia slurry and other slurry chemical reaction, the granulator becomes a usable compound fertilizer product. . With the high utilization of compound fertilizers, the application of rotary drum dryers is becoming more and more widespread.


As the key equipment for NPK fertilizer production line, drum granulators are mainly used as compound fertilizer equipment. Both hot and cold granulation and high, medium and low concentration compound fertilizers are suitable for large-scale production of drum granulators. Perform necessary operations on the materials to be processed use steam and heating to adjust humidity, increase the temperature of the granulated material itself, reduce the moisture content of the granulation, reduce the load on the dryer, improve work efficiency, and add materials from the feeding end. Through the role of the inside of the cylinder and the special structure inside the cylinder, it is made into granules, and finally flows out through the discharge port, and the material is processed into a specific shape by a rotary granulator.

The drum pelletizing rate can reach 90%, and the equipment is simple to operate, flexible in work, and easy to maintain. The specific advantages are as follows:
1. Increase the temperature of the material during the operation of the rotary granulator, so that the moisture content of the material after pelleting is low, and the drying efficiency is improved.
2. The drum granulator is lined with rubber engineering plastic, and the raw materials are not easy to stick to the cylinder, and it has the function of anticorrosion and heat preservation.
3.Ultra-high molecular weight polyethylene is used to build the lining of the granulator equipment, which eliminates the phenomenon of sticking walls of materials and reduces the labor intensity of workers.
4. The drum granulator has large output, low power consumption, low maintenance cost and long service life.

Drum granulator, as a forming machine that shapes materials into a specific shape, has become efficient production equipment in the compound fertilizer industry by virtue of its high-yield operations in compound fertilizer production applications.
