ZKS vacuum feeder unit is using whirlpool air pump extracting air. The inlet of absorption material tap and whole system is made to be in vacuum state. The powder grains of material are absorbed into the material tap with ambient air and formed to be the air flowing with material. Passing the absorption material tube, they arrive to the hopper. The air and materials are separated in it. The separated materials are sent to the receiving material device. The control center controls the “on/off” state of pneumatic triple valve for feeding or discharging the materials.
In the vacuum feeder unit the compressed air opposite blowing device is fitted. When discharging the materials every time, the compressed air pulse oppositely blows the filter. The powder attached on the surface of filter is blown off for ensuring normal absorbing material.
