Working principle:

Vacuum feeder is a vacuum feeding machine by using pneumatic vacuum pump as vacuum source, with this vacuum feeder materials could be directly from container to mixer, reactor, hopper, sheet press, packing machine, vibrating griddle, pellet trimming machine, hydro-state palter, dry-state pellet disintegrator. To use this feeder could lighten workers labor intensity, put an end to powder pollution and ensure the at production process meets GMP requirements.
When "ON/OFF" key is pressed, compressed air gets into vacuum pump and the discharge of the hopper. Driven by Pneumatic cylinder. Is closed. Vacuum is stabled in hopper. Vacuum feeder will form an air current under vacuum. Operated by this current, material is fed to vacuum hopper via hose. After a period of time( feeding time, adjustable). Compressed air is cut off, pneumatic vacuum pump could not generate vacuum and the discharge of the hopper. Driven by pneumatic cylinder, gets open the vacuum in vacuum feeder disappear and material is automatically discharged from the discharge into receiving machine( such as sheet press and packing machine). Meanwhile, compressed air stored in the air of time( discharge time, adjustable). Compressed air is restarted, Pneumatic vacuum pump generated vacuum, discharge is closed. Vacuum feeder feeding material again. In this way the feeder works in cycles to make the material fed into receiving machine continuously.
For the vacuum feeder with material level control automatic feeding is realized with the hopper of the material-receiving machine through materials level control. When the material level is higher than a position in the hopper to the material receiving.

The vacuum feeding machine consists of vacuum pump(oil-free or water-free, ), vacuum hopper, filter(polyester coated, pe, 316L stainless steel, titanium),compressed air backflushing device, pneumatic feeding door device, automatic material level control device, stainless steel suction nozzle, conveying hose. The whole equipment is well designed and manufactured.
