Several factors affecting the granulation of fertilizer granulator
1. Effect of material temperature:
The temperature of the material directly affects the production capacity of the granulator. The height here refers to the distance between the material temperature before granulation and its melting point or softening point. Generally speaking, the higher the temperature, the smaller the yield. Therefore, for the material with too high material temperature (generally more than 50 ℃ above melting point or softening point), it is suggested to conduct heat exchange treatment on the material before granulation, so as to give full play to the production capacity of fertilizer granulation machine.
2. Influence of material properties:
The granulation properties of materials with different characteristics are quite different. The main physical parameters affecting granulation process and quality are melting point (or softening point), specific gravity, heat transfer coefficient, specific heat, crystallization characteristics, viscosity and liquid surface tension. Viscosity and surface tension mainly affect the molding quality of organic fertilizer granulation machine products, while other parameters mainly affect the cooling and solidification speed of materials, thus affecting its output. Generally speaking, the higher the melting point, specific gravity and heat transfer coefficient of materials are, the smaller the specific heat is, and vice versa.
3. The comprehensive effects of viscosity (or surface tension) and temperature on the molding quality of particles are as follows
The influence of material temperature and liquid viscosity on the shape of particles. The higher the viscosity and surface tension of the material at the corresponding temperature point, the fuller the hemispherical particles are; on the contrary, the flatter the hemispherical particles are. For general materials, the viscosity of molten materials decreases with the increase of temperature. However, our experimental study found that sulfur showed the opposite trend with other materials in a temperature range near the granulation temperature point. The discovery of this characteristic is particularly important for our technical practice in sulfur granulation.
