when compressed air enter into the vanuum pump, simultaneously under the push of air cylinder, the empty door of hopper will be closed and the vacuum will be formed in the hopper. The cacuum feeding machine forms air stream under vacuum state. Under the action of this air steam the material which is conveyed will be transported to vacuum hopper through hose. Certain time later (feeding time, adjustable), the compressed air is closed, the pneumatic vacuum pump is unable to produce vacuum, simultaneously under the push of air cylinder the emptying door of hopper will be opened and the cacuum will be disappeared in the vacuum feeder. The material will be fed into receiving equipment from the emptying door (for example tablet press, packing machine and so on),simultaneously, compressed air that stores up in air packet's blowbacks the filter, and the filter cleans by itself. Certain time late (discharging time, adjustable), the compressed air starts again. Move in cycles, the material is fed into the equipment continuously.
Why choose vacuum conveyor
Electrical vacuum conveyor Penumatic vacuum conveyor
For the vacuum conveyor with material level controller, automatic feeding of material in the hopper of the material receiving equipment can be realized through material level controller. When the material level is higher than ceitain position in the hopper of the material receiving equipment, the vacuum conveyor stops feeding, when the material level is lower than certain position in the hopper, vacuum feeder starts feeding automatically. And feeding for the material receiving equipment is completed. vacuun conveyor uses compressde air to produce high vacuum through the vacuum generator, and then convey materials. With this vacuum feeder materials could be fed diretly from container into mixer, reactor, hopper, tablet press, packing machine,vibration sieve, straightening granulator, wet granulator, dry granulator and disintegrator. Using this feeder, workers'labor intensity could be reduced, the dust pollution will be eliminated and ensure that the production conforms to the requirement of GMP.
