This new ribbon mixer improves plant hygiene

| By Chemical Engineering

Munson Machinery

The model HD-3.5-9-SS ribbon blender features an integral bag-dump station that collects dust generated during manual dumping activities, improving worker safety and plant hygiene. Dust is drawn onto the cartridge filters of the dust collector, as nozzles within each filter alternately emit short blasts of air on a timed cycle, serving to dislodge accumulated dust and maintain vacuum efficiency. The unit can blend up to 85 ft3 (2.4 m3) of powders, pastes or slurries in 5–10 min, depending on the application. The mixer’s length-to-diameter ratio and split double-helical agitator (photo) reduce the time required to uniformly distribute particles having dissimilar sizes, shapes and bulk densities throughout the batch. Available options include a removable safety-interlocked grate on the dump station for additional interior access, spray lines for liquid additions, a central inlet port, multiple discharges, special drive arrangements and clean-in-place manifolds. — Munson Machinery Co., Utica, N.Y.
