Gravimetric Feeder – NX-S/NX-T series


Kubota’s Gravimetric Feeder – NX feeder is an unique Feeder with Innovative design which helps to handle wide range of materials with High performance.

  • High Feeding Accuracy: from Digital load cell to Feeder all we manufacture in Japan.
  • Easy Maintenance Design
  • Demonstration is available with real machine at our FTC.

Innovative Design


Agitator is placed diagonally and rotates very close to Hopper which gives less effect on weight value, it realizes stable feeding.


Improvement of Anti Bridging function because material compression is decreased by negative wall angle design, it helps to handle wide material applications.


This structure Increases high screw fill of material as agitator pushes material into screw part. Compared to our conventional equipment, it achieves accurate and constant material flow.
