FlexWall®Plus FW40/7 Volumetric and Gravimetric General Information The FlexWall®Plus FW40/7 feeder is ideal for poor or difficult flowing bulk ingredients. The feeder has the following main components: a stainless steel trapezoidal housing, flexible polyurethane trough with a large cross-section, external massage paddles with separate drive, a screw, a screw tube, a 3 phase motor and a trapezoidal extension hopper with volumes of 50 dm³ (1.77 cuft) or 70 dm³ (2.47 cuft). The shape of the trough and the external adjustable amplitude massage paddles work together to provide consistent screw filling and mass flow without ingredient deterioration. The FW40/7 features a separate paddle drive to allow paddle speed adjustment for difficult flowing ingredients. Screw removal of the FW40/7 is from the front of the feeder. The FlexWall®Plus is easily disassembled for wet or dry cleaning as the polyurethane hopper that is attached to the housing. Moreover, the compact trapezoidal shape allows up to 6 feeders to be arranged around a central feed point. Service can be from the front or back. The gravimetric version includes the analog weighing system MS5, or the digital weighing system MD5 (for highest measurement accuracy), featuring a high resolution robust digital load cell with serial data transmission and advanced filtering technology. The unit conforms to CE directives.

FlexWall®Plus FW40/7 Volumetric and Gravimetric Available Screw Sizes and Feed Rates Screw type Tube designation Max. feed rate* [cuft/hr] Spiral screw (S) (TA=with trough activation) Spiral screw (S) for granules * Theoretical values at 100% screw filling level and motor speed. Depending on the flow characteristics the screw filling level may decrease to 50%. Further limitations have to be considered for gravimetric feeding, as max. speed should be reduced to allow for bulk density variations. ** Available upon request How to read the table of screws Technical Specification Ambient temperature:...
