Measuring Volumetric, weight, weightless, continuous?or?batch are techniques implemented in mixers and metering devices. Gravimetric Batch Blending Systems Batch mixing systems is an advanced gravimetric batch dosing system, which is suitable for dosing plastic material: granule, powder, regrinds by digital weighing technique. It is applicable on injection, extruder, blowing molding process etc. The accuracy of proportion is up to ± 0.5%, and capacity up to 1000kg/hr. Volume type Mixing Dosing Use stainless steel screws are through a static blender, enable the raw material entrained master batch into the screw barrel, the accuracy of proportion is up to 1%
