Adjustment Method for Airflow in Electric Stone Mill Flour Machines

The airflow system is indispensable in the production of electric stone flour mills. Users must adjust the air volume appropriately according to the actual characteristics of the material to ensure the quality of the finished product. However, many operators lack knowledge on how to regulate airflow. Therefore, today we shall outline the following:

　　When regulating airflow in electric stone flour mills, one must account for variations in batch weight pressure, impurity types, and unforeseen circumstances. Airflow originates from two sources: the air separator, which uses air currents to isolate impurities; and the blower, which propels material movement within transport ducts.

　　When employing an air separator with an electric stone mill flour machine, the separation of impurities relies on the difference in suspension velocity between wheat and impurities, utilising the propulsive force of air. In actual production, air volume adjustment for the air separator is typically achieved via an air damper to control the velocity of the ascending airflow. Light impurities carried away by the airflow are generally separated and collected by various dust collectors within the air network.

　　We regulate air velocity by adjusting the position of the control device. Within the airflow channel, excessively high velocity in the upper section may draw away material, reducing flour yield, while insufficient airflow proves ineffective. At optimal air volume, wheat entering the separation zone of the electric stone mill flour machine moves horizontally under the rising air current, aiding the airflow in penetrating the layer and carrying away light impurities.
