Granules loss-in-weight feeder TrueWeigh™

powderfor plastic pelletsgravimetric

Overview
TrueWeigh™ Continuous Blenders provide precise loss-in-weight dispensing of dry solids across a wide range of particle sizes and bulk densities, including pellets, regrind, micro-beads and powders. They deliver consistent, repeatable blends for extrusion processes requiring high homogeneity and accurate dosing. Units are designed for extrusion rates to 3,000 lb/hr (1,360 kg/hr) and are available with up to six component positions.

Key features

• Machine- or stand-mounted configurations: machine-mounted includes a TrueWeigh™ gravimetric hopper mounted to the feed throat for direct feed-rate monitoring or optional extrusion yield control; stand-mounted feeds material exiting the static mixer through a central tube to a remote destination.
• Integral loading platform: canopy cover offers a stable mounting surface for hopper material loaders.
• Full hopper visibility and alarms: material levels, ingredient type and position are visible; each bin is weighed and automatic audible alarms are available per ingredient.
• Quick material and auger changes: quick-change feed augers (0.5–2.0 in diameter); slide gate enables auger swaps with material in the hopper; auger motors removable with quick-release clamps; inclined auger tube allows complete draining.
• Conical cascade static mixer: static mixing chamber produces highly homogeneous blends without mechanical agitation, preventing separation from ledge- or step-type cascades.
• PLC-based control with learning algorithm: maintains each component to +/- 0.5% of set point by monitoring and adjusting feeders for flow and bulk density variations.
• Materials handled: virgin pellets, regrind, micro-beads, powders, granules, flakes, concentrates and additives; each component metered through material-specific augers.
• Optional extrusion yield control: blender PLC can interface with an extruder via optional drive/encoder/haul-off cards to control line speed and weight-per-length to +/- 0.5% of target.

Frequently asked performance items

• Accuracy: PLC-based control delivers accuracy to +/- 0.5% of set point.
• Blend capability: homogenously blends dissimilar materials using material-specific feed augers and the conical cascade static mixer.
• Extrusion yield control (optional): drive/encoder/haul-off add-ons enable closed-loop yield and weight-per-length control to +/- 0.5%.
