The Pneumatic Vacuum Feeder is used compressed air through vacuum parts to make a high vacuum condition to transfer the material,it doesn't used the machinery pump,so it has the simple structure,with small volume,lower noisy,convenient controlling,it could eliminate static and doesn't need repair,The machine is according with GMP .The high vacuum condition is avoided layered phenomena,so to protect the uniformcomposed mixing materials.It is the best machine for feeding t Tablet Press,Dry Granulator,Packing machine,Pulverator and Vibrate sifter automatically.
   When the compressed air input to the vacuum motor,the vacuum motor could make the negative pressure and has the vacuum airflow.The material could absorb into the feeder,and through tube into feeder chamber.The filter could separate the air and the material.When chamber is full,the controller will cut the air supply automatically,the vacuum motor will stop,at the same time the chamber door will open and the material will into the funnel.While the compressed air will through impulse valve to cleaning the filter automatically.When the time is ready or sensor will give the signal,the feeder will start automatically.
