Drum granulator is a molding machine that can produce materials into specific shapes. The rotary drum granulator is one of the key equipment in the compound fertilizer industry, suitable for large-scale production of cold and hot granulation as well as high, medium, and low concentration compound fertilizers. The main working method is wet granulation of granules, which uses a certain amount of water or steam to fully react the basic fertilizer after being humidified in the cylinder. Under certain liquid phase conditions, the rotating motion of the cylinder generates squeezing force between the material particles to aggregate into balls. Rio Tinto Technology has many years of experience in the production of compound fertilizers. The rotary drum granulator developed by lito has the characteristics of beautiful appearance, simple operation, low energy consumption, long service life, and easy maintenance.

　　Its main characteristics are as follows:

　　1. Low investment, quick results, good economic benefits, and reliable performance;

　　2. Small power, no three waste emissions, stable operation, easy maintenance, reasonable process layout, and low production costs;

　　3. High ball strength, good appearance quality, corrosion resistance, wear resistance, and low energy consumption;

　　4. The ball formation rate reaches 70%, with a small amount of return material. The particle size of the return material is small and can be re pelletized

　　5. The cylinder is lined with special rubber plates or acid resistant stainless steel plates, achieving automatic scar removal, tumor removal, and eliminating the traditional scraper device;

　　The working principle of this series of rotary drum granulators is that the belt and pulley are driven by the main motor, and transmitted to the driving shaft through a reducer. The gear installed on the driving shaft meshes with the large gear ring fixed on the machine body, working in opposite directions. The material is added from the feeding end, rotated by the cylinder, and under certain conditions, it is made into particles, and finally flows out through the discharge port. Due to the continuous influx of materials and the continuous rotation of the granulator, large-scale production can be achieved.

　　The whole machine can be divided into five main parts:

　　1. Bracket part: The entire rotating part of the body is supported by the bracket, which bears a large amount of force Therefore, the supporting wheel frame of the machine is made of medium carbon steel plate and channel steel welded together, and has passed strict quality control and special process requirements, achieving the purpose of using this machine. In addition, what is more important is the bracket fixed on the frame. Considering the significant friction between it and the rolling belt of the machine body, our factory has specially selected high-quality anti-corrosion and wear-resistant materials, greatly improving the service life of the machine. The bracket frame also adopts casting integrated technology In addition, there are lifting hooks at the four corners of the roller frame for easy loading, unloading, and transportation

　　2. Transmission part: The transmission part of the entire granulator is crucial for the overall operation of the machine The transmission frame is welded with high-quality channel steel and has passed strict quality requirements The main motor and reducer installed on the transmission frame are both selected as ISO national inspection free products, with reliable quality The electric motor drives the pulley, V-belt, and reducer to drive the main shaft, making the machine work. The transmission reducer is connected to the working part of the main shaft and uses a nylon coupling to interlock and transmit the drive.

　　3. Large gear: fixed on the machine body, meshing with the transmission small gear to drive the machine body in opposite directions. It uses high-tech wear-resistant materials to extend the service life of the machine.

　　4. Rolling belt: fixed to both sides of the body to support the entire body.

　　5. Body part: The most important part of the entire granulator is the body part, which is welded with high-quality medium carbon steel plates and equipped with special rubber lining plates or acid resistant stainless steel lining plates to achieve automatic scar removal and tumor removal. It eliminates the traditional scraper device and achieves the purpose of the machine through strict quality control and special process requirements.rotary drum granulation production line
