The frequency of the fluidized bed fan has an important impact on the performance and granulation effect of the fluidized bed fan. First of all, the frequency is an important parameter of the fluidized bed fan, which affects its performance and efficiency. The higher the frequency, the faster the speed of the fan, and the greater the flow rate of the air out, thus improving the suction capacity and operating efficiency of the fan. However, too high a frequency can also lead to increased fan noise and vibration, and may cause damage to the equipment.
Secondly, the change of the frequency of the fluidized bed fan will affect the change of air volume and pressure, which will affect the specific surface area, porosity and other physical properties in the granulation process. The specific surface area of the sample prepared at the higher frequency is smaller, while the sample prepared at the lower frequency has a larger specific surface area. At the same time, there are more fine porosities at higher frequencies and more macroporosity at lower frequencies. There are large differences in the physical properties of granulated products produced at different frequencies.
Therefore, in the process of fluidized bed granulation, it is necessary to select the appropriate frequency of the fluidized bed fan according to the specific process requirements and equipment parameters to ensure the granulation effect and the normal operation of the equipment.
