Consider the required airflow and pressure:
When selecting a blower, the primary factors to consider are the airflow and pressure required by the pneumatic conveying system; a certain margin of safety should be included to meet actual production needs.
Consider pressure fluctuations during material conveyance:
In addition to airflow and pressure, one must consider pressure fluctuations during the conveying process. Airflow variations should be minimized to reduce their impact on the material's flow state and prevent pipeline blockages. For instance, due to the inherent characteristics of centrifugal blowers, pressure fluctuations can significantly affect the conveying process.
Consider factors such as conveying distance and height:
Different blowers have limits regarding horizontal conveying distances. Generally, a Roots blower is suitable as the air source for pneumatic systems with a horizontal conveying distance of up to 300 meters; beyond this distance, equipment such as air compressors may be required. The impact of conveying height follows a similar pattern: the greater the vertical height, the higher the operating pressure required by the blower.
4. Consider the quality of the blower itself:
Finally, ensure the quality of the blower itself-such as the wear resistance and durability of the rotor-to guarantee reliable operation. At the same time, opt for blowers with simple, compact designs to facilitate maintenance and management while reducing operating costs.
