Principle of operation
The DOSIGRAV blending principle is based on a very accurate, individual and simultaneous weighing of small quantities of each component. The input and output of the material from each individual weighing unit relies on proprietary special variable flow rates valves. All system is patented.

Blending is not affected by variations in density, shape or compactness of materials and vibrations. The parts in contact with material are easily removable without the use of any tools, fast cleaning and material change. A modular design makes possible the use of identical parts for all components. Furthermore, a very simple control panel that can be installed up to 20 meters from the blending unit makes the operation extremely easy and intuitive.
