MWF-101 Weigh Belt Feeder

Model MWF is a widely recognized general purpose low capacity weigh belt feeder designed to operate accurately and reliably in harsh industrial environments with minimal maintenance. It can be used with an open loop belt drive to gravimetrically measure the flow of material, or with closed loop control to operate as a feeder and regulate the flow to aconstant or dynamic set point.

A standard design coupled with dimensions and ratings that are tailored to each application add versatility to its capabilities. Its design for ease of maintenance and change of its ratings gives it a long useful life in a rapidly changing industrial environment.

When connected to the THAYER family of instrumentation it can be consistently and accurately calibrated and the measurements can be presented to operators and supervisory controls seamlessly through a variety
of standard industrial interfaces. The instrument can control the flow of material as a master feeder or as a slave proportioning its feed rate to some other master signal.

• Low rate feeder, feed rates to 25,000 lbs/hr @ 50 pcf.
• Very small size: 25 inlet to outlet
• Handles wide range of materials and densities
• Sanitary, stainless steel construction
• Totally enclosed for effective dust control
• Easy access, low maintenance design
• Totally removable scale assembly needs no recalibration after reinstallation
• Excellent accuracy and stability
• Rugged contruction-built to survive
• Tough feeder for small spaces
• The MWF-101 feeder provides Thayer Scale accuracy, ruggedness and reliability in the smallest possible package, for precise material control in tight plant layouts.

Head pulley drive increases reliability and reduces measurement errors. Self cleaning tail pulley eliminates material build up and belt tracking problems. Unique flared skirt design prevents material spillage and assures proper feed control. Rigid scale support system provides exceptional stability, assuring accuracy without frequent recalibration.

Belt velocity is measured from the pulley, not the drive motor, providing a direct measurement and control of the material. Totally enclosed, gasketed design assures safe, dust free operation even when handling fine powders. The strain gage load cell assembly can be easily removed then reinstalled without recalibration of the feeder.
