Pneumatic vacuum feeder uses compressed air to generate high vacuum through a vacuum generator to transport materials, without the need for mechanical vacuum pumps. It has the advantages of simple structure, small volume, low noise, convenient control, and elimination of material static electricity. The high vacuum generated by the vacuum generator can effectively avoid the stratification phenomenon of the mixture and ensure the uniformity of the material composition. It can be well matched with equipment such as tablet press, capsule filling machine, dry granulation machine, packaging machine, crusher, vibrating screen, etc

1. The conveying capacity is the theoretical limit conveying capacity measured under experimental conditions using powder with a bulk density of 0.5 and good flowability as the test carrier;
The measuring distance for the conveying capacity of QVC-1/QVC-2 is within 3 meters (conveying length+lifting height), and for other models it is within 4 meters;
3. Material characteristics and conveying distance have a significant impact on the conveying capacity, and the conveying distance is inversely proportional to the conveying capacity;
