PRO-GRAV continuous gravimetric dosing
Loss-in-weight dosing and extruder control for continuous material-flow regulation.
Represented in Vietnam by Song Song
Overview
Product details
Continuous weighing
PRO-GRAV measures material consumption through a weighed hopper and uses the result to control extrusion throughput. The loss-in-weight approach follows the actual material mass rather than relying only on volumetric feeding assumptions when bulk density changes.
Recipe and extrusion control
Up to six gravimetric dosing units can be combined with the main material stream. Additives and masterbatch are introduced above the extruder feed and synchronised with extrusion. In coextrusion, control can coordinate the throughput of individual extruders with the intended layer structure.
Configuration note. Feeder size and achievable dosing performance depend on the material, recipe proportions and throughput. Confirm these inputs for each extruder.
