There are several methods to improve the flowability of powder during transportation:
The particle shape of the powder can be controlled by changing the operating conditions during the grinding or spray drying process to affect its fluidity.
Powder can be added with flowability additives, such as granular substances such as silica or alumina, to improve its flowability.
For powders that are difficult to flow, vibration, heating, or airflow can be used to promote their flow, such as adding vibration devices in conveying pipelines, bucket feeders, vibrating feeders, or using heaters to maintain a certain temperature.
During the transportation process of powder, it is necessary to avoid stacking, as stacking can affect the fluidity of the powder. Stacking can be avoided by installing slopes, increasing transportation pipelines, and other methods.
