Drum Compound Fertilizer Granulation Equipment Selection
The production process of compound fertilizer and NPK fertilizer is inseparable from the drum granulator. In the last article, we mentioned the use of drum granulation compound fertilizer equipment. Let’s review the working principle of drum granulator.
Drum granulation equipment is mainly composed of drum, front support wheel, rear support wheel, big gear, reducer, motor, etc. The inner part is composed of granulation area, feed area, steam nozzle and annular ring. When working, powdery raw materials and returned raw materials are added from the feeding port, and the rotating roller rotates upward with the animal material layer.

When it reaches a certain height, the material will fall along the arc track under the action of gravity and inertial force. Steam or water is injected into the cylinder and then sprayed on the rolling material layer to condense the material into particles. There are many problems in the use of drum granulation compound fertilizer production line. For example, the lining of the drum granulation equipment needs frequent maintenance at high temperature, and there is material agglomeration on the inner wall of the granulation equipment in the drum granulation equipment. How to solve these problems? Let’s take a look at today’s focus, drum granulation compound fertilizer production equipment transformation.
The purpose of technical transformation of drum granulator fertilizer production equipment is to provide a granulator with non sticky inner wall and elastic adjustment of the position of the retaining ring, so as to achieve balanced and stable load, so as to produce high-quality compound fertilizer and adapt to the changes of high, medium and low concentration compound fertilizer types.
After years of research and test, Zhengzhou SX compound fertilizer equipment manufacturer found that chloroprene rubber was used as lining of pelletizing equipment. During operation, when the material reaches the lowest point through the cylinder, the weight of the material will be the difference between the rubber film and the cylinder wall. The indoor air is discharged from the granulation tube with breathing hole, which is the largest contact area between materials. When the material moves to a certain height with the roller, the material will fall and roll under the action of gravity and pressure, and the material will hardly adhere to the film. This fundamentally solves the problem that the material adheres to the inner wall and scabs, and the particle size of the material is uniform and beautiful.
