• 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.

Volumetric Dosing Systems with Dosing Cylinder
The dosing cylinder guarantees a uniform and repeatable flow throughout a wide range of applications. The specific design guarantees that the master batch is blended uniformly and precisely. The avoidance of any pulsing during blending provides maximum control of the process and the end product.
