Special advantages:

  • Precision feeding to several production lines
  • Flexible conveying in lines
  • High-quality nickel chromium steel design
  • Sturdy construction suitable for vibration-assisted operation
  • High output in coarse-stream and supreme metering accuracy in fine-stream operation
  • Easy inspection and cleaning due to quick-release clamps

Preferred applications:

For continuous and discontinuous conveying and metering of bulk materials in several conveying lines and scales etc. These units can be used for almost all kinds of bulk materials in the food, plastics, chemical and pharmaceutical industry.

Functional principle:

The bulk material enters the second screw via the product inlet of the first screw and is then transferred to the screw outlet. The metering screw is activated and rotates picking up product and conveying it uniformly to the screw outlet. The frequency control of the drive changes over from coarse to fine metering in metering and weighing operations. This means that the speed of the metering screw is reduced correspondingly. When the set weight has been reached, a pneumatically operated shutoff valve closes the screw outlet.
