Gravimetric Dosing & Mixing

Gravimetric dosing and mixing
Load cells of the highest accuracy are used, weighing to within 0.01 g.


For complex and demanding dosing and mixing tasks, GraviMaster is the ideal solution.

GraviMaster is designed to handle virgin materials, regrind, masterbatch and other additives.
GraviMaster blending systems are available in more than 20 different models with a throughput capacity range from 10-750 kg/h for the standard units.
The number of components on the standard unit is 2-6.

But purpose-built units may be designed for additional feeds up to a max. of 10 and a throughput capacity up to 1500 kg/h. This gravimetric blending series is suitable for injection moulding, extrusion and blow-moulding applications. The system is capable of extremely accurate measurements of additive, even at very small percentages or ratios.


The GraviMaster has 3 ways of dispensing:
Gravimetric and volumetric, one mode can be selected or a combination of both.

A unique integrated regrind control system is successfully solving many customers’ problems with storage and reuse of regrind material.

Owing to the modular construction the GB 10 series can be supplied in 6 different configurations, from 2-7 hoppers.
