Measuring system with weighing controller, a system to perform high precision feeding of difficult-to-handle materials continuously, or batchwise.

Using Circle Feeder technology, the system provides continuous uniform-rate feeding even of difficult-to-discharge materials with poor fluidity.

  1. Mass flow and uniform-rate feeding are realized.
  2. Bridge and segregation of materials is prevented.
  3. Lower requirement for drive power.
  4. Dischargeable of very difficult-to-handle materials.
  5. Less noise and vibration.

The loss-in-weight continuous uniform-rate feeding system (LWF series) is equipped with a loss-in-weight controller customized especially for the Circle Feeder. Even powders of very low fluidity can be discharged continuously at a uniform rate with high precision.


Model LWF-200S LWF-700S
Designed feed rate (m3/h) 0.084 ~ ~ 2.3
Accessories load cells, summing box, controller etc

※LWF-300S/500S type are also available.

  • Specifications are subject to change for improvement or from necessity of properties of material.
  • Main construction in stainless steel 304, carbon steel and others available.
