Brief Introduction to Rotary Dryer on Wind Volume Control

Here is some basic information about the air volume control: the adjustment of air volume includes 2 parts-the hot wind and the cold wind. With different situations in real production, for example: different materials and moistures would require different temperatures, the hot wind and cold wind control differs to these situations too, while their purposes are the same-to realize the automatic control of wind volume of the rotary dryers, reduce the human factors to make the wind volume control more scientifically with higher accuracy and precision.

The Hot Wind Volume:

With the air valve designed in the hot wind volume controlling system, the wind volume is divided into several levels, and we choose the right level in accordance with the real situations.

The Cold Wind Volume:

The basic theory of cold wind volume control is through the adjustment of the rotation speed of axial flow fan, the sensor record the current temperature, compare with the preseted data, make the adjustment of frequency converter after the calculation, thus the rotation speed is changed.

The information above is only about the theory, while the real production is not that simple, but this is the very first step to master the operation of the wind volume control in the drying processes, if you have further problems or questions, please contact us now.
