Precision Blending

Auxiliary Equipment

WITTMANN Blenders

Gravimax material blenders and Dosimax feeders are of highest precision and are continuously improved.

Gravimax Gravimetric Blenders

The Ultimate in Precision Blending
Gravimax blender models Series 1, 3, 7, 9, and 18/27 for batch sizes from 1 to 27 kg (2.2 to 60 lbs.)
 

Advantages of Gravimax Blenders

  • Simple operation
  • Highly precise metering valves made from stainless steel for high abrasive wear applications
  • Interchangeable steel hoppers with self-closing valve mechanism
  • “Clip-on” corner window provides full view for material inspection
  • Easily removable weigh bin
  • Uniform material blending using a highly efficient spiral mixer
  • RTLS Technology uses progressively smaller dispensing algorithms to approach the target weight
     

Gravimax Touch-screen Control

  • High-capacity microprocessor controller
  • Designed for Simplicity, Ease-of-use and High Efficiency
  • Control of up to 8 components
     

GraviLog is the name of a software solution that has been especially developed for data recording of gravimetric blenders of the WITTMANN Gravimax G series. This comprehensive software makes it easy to analyze various differing factors, for example the material consumption of several devices in regard to a special working process. And using GraviLog makes it possible to generate graphical representations for target and performance values.
