The BEST TSF  twin-screw feeder from Metso Minerals is designed for precise batching and weighing applications. The company believes the feeder also provides:
- Accommodations for fast high-volume filling with accurate dribble flow at the end of the cycle.
- A compact footprint, ideal when space prohibits multiple single-screw units.
- A double-helix design—with one helix measuring 1-1/2 in. (dia.) and the other measuring 4 in. (dia.)—mounted on an 18- by 22-in. hopper.
- Helix ratings of 17 and 283 ft.3 per hour, respectively, at maximum RPM with efficient conveyable product and no slippage.
- Suitability 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.
- Availability of many options.
