Developed to meet the needs of small-part molders, the new ultracompact TrueBlend TB-T blender from Conair delivers precise material blends from up to four ingredients at extremely low throughputs — from just one lb/hr up to 100 lbs/hr — with blend accuracy of ½ of one percent.

Standing at less than 24 in. tall, this ultracompact gravimetric batch blender mounts easily on a machine feed throat or on the new Conair TB-T blender stand for use as a central color and additives blender. 

The TB-T blender was designed with high blending precision and easy maintenance in mind. It is equipped with a 7-in. LCD touchscreen control that features Conair’s “common control” interface for quick and easy setup. Its microprocessor control can manage multiple loaders and pumps. Like larger Conair blenders, the TB-T relies on “feed forward” dosing, using multiple small dosing cycles to deliver a more precise material mix into the weigh chamber prior to mixing. The control calibrates after every dosing cycle to compensate for variations in dispense method, resin bulk density or particle geometry.  

Unlike some blenders that bolt a material loader directly to the removable hopper — an arrangement that complicates hopper removal and cleaning — the TB-T design includes a loader-mounting plate that holds loaders firmly in place above the hoppers, yet enables independent removal and cleaning of each of four lockable material bins.

Each compact hopper (approx. 0.15 ft³ capacity) has an integral gate that remains closed during hopper removal, but opens easily for emptying and cleaning, prior to reinstallation. 

When in operation, each slide gate is connected directly to an air-cylinder rod from the vacuum manifold to ensure positive actuation while eliminating troublesome clevis-pin connections.
