Detailed Product Description

Vacuum feeder is a vacuum feeding pneumatic vacuum source. With this vacuum feeder materials could be fed directly from container into mixer, reactor, hopper, tablet press, packing machine, vibrating griddle, pellet trimming machine, wet granulator, dry granulator and disintegrator. To use this feeder could lighten workers's labor intensity, put an end to power pollution and ensure that the production process meets GMP requirements. 

Operating Principles

When presses down the key ON/OFF, the compressed air enters the vacuum pump, simultaneously under the air cylinder impetus the hopper puts the material gate to close, and in hopper produce vacuum. The vacuum feeding machine forms a airflow under the vacuum. Under this air current's function, the material which is transported after the hose is transported to the vacuum hopper. After certain time (feeding time, but adjustment) , the compressed air is closed, the air operated vacuum pump is unable to , simultaneously the hopper puts the material gate to open under the air cylinder impetus, vacuum of the vacuum feeding machine vanishes. And the material from the material gate puts to the equipment (for example tablet press, packaging machine and so on), simultaneously, compressed air that stores up in air packet's instead blows the filter, and the filter cleans by itself; After certain time (puts material time, but adjustment), the compressed air starts again, the air operated vacuum pump produces vacuum, and puts the material gate closure. The vacuum feeding machine feeds material once more, starts once again, the material is sent into the equipment in continuously.

For the vacuum feeder with material level control automatic feeding is realized with the hopper of the material-receiving machine through material level control. When the material level is higher than a position in the hopper of the material-receiving machine, vacuum feeder stops feeding, but when he material level is lower than a position in the hopper, vacuum feeder starts feeding automatically. And feeding on the material-receiving is completed.
