Twin Screw Feeder NXT26 (Smart) Volumetric and gravimetric General Information The NXT26 feeder is ideal for poorly flowing, sticky powders as well as fibers and granules. The feeder has the following main components: a screw trough with negative wall angle structure, a gearbox, an inclined agitator in the screw through, a smart motor for the agitator, a twin screw, a smart motor for the screw drive, a screw tube and an add-on hopper for a total bulk storage of 50 dm³ (1.8 cuft). These components work together to ensure the mass flow of the bulk material and a uniform screw filling level, as both the agitator and the hopper geometry prevent bridging and ensure optimum bulk material flow into the screw. The NXT26 is easily disassembled for wet or dry cleaning. All service is from the front or back. The gravimetric version includes the Weighing system MD5 featuring a high resolution digital load cell with serial data transmission as well as MS5 with strain gauge load cell, all of which feature filter technology to compensate for interference. The unit conforms to CE directives. Model Specification Screw drive Servo motor Drive power Screw speed Trough agitator Agitator drive Drive power Control Modules Control and speed modules are offered either mounted onto the feeder (Congrav® CM-E) or are available for mounting in a separate control panel (Congrav® CB-E). Controls can communicate directly to most host/ PLC systems.

Depending on the flow characteristics the screw filling level may decrease to 50%. Further limitations must be considered for gravimetric feeding as max. speed should be reduced to allow for bulk density variations.
