Twin-Screw Feeder

BEST Model TSF twin-screw feeder from Metso is designed for precise batching and weighing applications.  The feeder’s dual-helix design combines fast, high-volume filling with accurate dribble flow at the end of the cycle.  Its compact design is ideal when limited space prohibits multiple individual screw units.  Two helixes—1½” and 4” in diameter—are mounted on an 18”x22” hopper.  They are rated at 17 cu. ft. and 283 cu. ft. per hour, respectively, at maximum RPM with 100%-efficient conveyable product and no slippage.  TSF is ideal for batching to weigh-hoppers; low loss-in-weight scale-monitored flow; low loss-of-weight batch applications with scales; drum and pail packout lines; and recipe-type batching by multiple computer-controlled units.  Many options are available.
