Ahmedabad-based Nu-Vu Conair Pvt Ltd launched TrueWeigh continuous blenders as part of bringing product range from from its US based partner Conair in the India market. The blender range launched at Plastindia 2015 at Gandhinagar, Gujarat provide extremely precise loss-in weight dispensing of dry solids of various size and bulk densities including pellet, regrind, micro-bead and powder.
“These highly consistent and repeatable blenders are ideally suited to extrusion processes that require perfect blend homogeneity and extremely accurate dosing,” explained Satish Godase, International Business, Board Director, Conair India at the Plastindia show..
Designed for extrusion rates to 3,000 lb/hr {1,360 kg/hr}, TWB, blenders are available with up to six component positions. The TrueWeigh continuous blender yield control option adjusts the extruder screw speed to compensate for material variations and other process variables while monitoring/controlling the haul-off speed – continually delivering precise dimensional stability at minimal tolerances.

“For extrusion high accurate mixing and blending is required, it has the capacity of 5 tonnes per hour with an option of going higher,” stated Satish Godase.
The PLC-based control holds each component to +/- 0.5% of its set point. The control uses a proprietary learning algorithm that simultaneously monitors and adjusts each feeder for material flow and bulk density changes.
Easily and accurately blend virgin pellets, free flowing powders, regrinds, granules, flakes, concentrates and additives. Each component is simultaneously metered through material-specific feed augers. A conical cascade static mixer integrates the materials and eliminates separation caused by ledge or step type cascades.
