introduction

As an important industrial raw material, alumina is widely used in metallurgy, ceramics, chemical industry and other fields. In the production process of these industries, efficient, stable and safe material handling is a key link to ensure production continuity and product quality. With its unique working principle and performance characteristics, intermittent vacuum feeder has gradually emerged in alumina conveying, bringing new solutions to the industry. 

Intermittent vacuum feeder working principle

The working process is generally divided into three stages: feeding stage, conveying stage and unloading stage. ​

In the feeding stage, the suction chamber of the charging machine is pumped to a certain vacuum degree through the vacuum pump to form a negative pressure environment. At this time, the suction nozzle connected with the suction chamber is placed in the alumina material pile, because the external atmospheric pressure is higher than the air pressure in the suction chamber, under the action of pressure difference, the alumina material is sucked into the suction chamber. ​

After entering the conveying stage, when the material in the suction chamber reaches the predetermined amount, the feed valve is closed to prevent the material from continuing to enter. The vacuum pump continues to work to maintain the vacuum in the suction chamber, and the discharge valve of the conveying pipe is opened. Under the action of vacuum suction, the alumina material is transported to the target container or equipment through the conveying pipe. ​

In the unloading stage, when the material is delivered, the vacuum pump stops working, and air is injected into the suction chamber to restore the air pressure in the suction chamber to normal pressure. At this time, the discharge valve is opened, and the material is discharged from the suction chamber to the target position by its own gravity, completing a conveying cycle.

Advantages of intermittent vacuum feeder for conveying alumina

1. Efficient delivery

2. Avoid material contamination

3. Adapt to various working conditions

4. Equipment maintenance is easy

conclusion

The intermittent vacuum feeder has shown many advantages in alumina conveying, such as high efficiency, environmental protection, strong adaptability and easy maintenance. By continuously optimizing equipment performance and improving the conveying process, the intermittent vacuum feeder will create greater value for alumina production enterprises and promote the development of the entire industry in a more efficient, green and intelligent direction.
