Thayer Scale has introduced the new MWF-SGSP-OS Ultra-Sanitary Open Construction Weigh Belt Feeder for processing of any application where reliability and weighing performance is paramount. The belt feeder can provide either a “closed loop” gravimetric control of material feed rate or an “open loop” control for precise convey rate output and totalization of an uncontrolled or intermittent material supply. The MWF-SGSP-OS Sanitary Weigh Belt Feeder has been designed for handling a wide range of materials and densities; positive belt tracking, without the use of mechanical devices, due in part to a unique belt tracking system; easy access, with a low-maintenance design and no tools disassembly; and fast belt removal due to a cantilevered frame. Belt velocity is measured from the tail pulley rather than the drive motor, providing a direct measurement of belt speed. According to the manufacturer, this improves both measurement and control of material. Furthermore, the load cell assembly can be easily removed, then reinstalled without re-calibration of the feeder.
