Drum granulation production is a process in which composite fertilizer equipment achieves thermal granulation of composite fertilizer. By increasing the temperature of the material and increasing the solubility of salt in the granulation water system material, the liquid phase quantity that meets the granulation requirements of the material is obtained at low moisture content, reducing the thermal energy consumption in the drying process, and improving the production capacity of the equipment. Therefore, the quality of granulation performance is the key to determining the yield and quality of composite fertilizer produced by drum granulation.
The time and frequency of material rolling in the drum granulator are the primary factors determining the balling rate and particle roundness.
The principle of compound fertilizer Organic fertilizer drum granulator is that materials rely on surface tension, appropriate liquid phase, extrusion force generated by rolling between materials, and small particles as the core in the correct movement direction of materials in the Organic fertilizer drum granulator, and absorb and adhere to small particles during rolling.
The higher the frequency of rolling within a certain period of time, the higher the sphericity rate, and the more rounded the particles become after forming. In the production process, we have encountered two situations due to the different friction between materials and compound fertilizer Organic fertilizer drum granulator.
1. Compound fertilizer Organic fertilizer drum granulator has a large internal surface finish, which reduces the friction between materials and cylinder wall and weakens the upward movement of materials. If materials do not roll, particles cannot be made. In view of this situation, we can solve this problem by adjusting the rotating speed of compound fertilizer Organic fertilizer drum granulator and installing a small board inside.
2. The reason is that the materials in the compound fertilizer Organic fertilizer drum granulator stick to the wall seriously, and the friction between the materials in the compound fertilizer Organic fertilizer drum granulator and the drum wall is increased, lifting the materials in the machine too high, causing the materials to fall down from the top, so that the particles formed are not round and there are too many large particles.
On the one hand, it is caused by too many sticky materials in the material. In this case, we adopt changing the process formula to reduce the amount of sticky materials used to solve the problem;
On the other hand, the internal roughness of the drum granulator for compound fertilizer Organic fertilizer is caused. We can solve this problem by changing the internal materials and increasing the smoothness of the drum granulator for compound fertilizer Organic fertilizer.
