Granules loss-in-weight feeder Circle Feeder

for poorly-flowing materialsfor solidsfiber

Product overview
The NTE Process Circle Feeder is a circular gravimetric extractor and dosing unit used for lumpy, normally cohesive, fibrous products that are difficult to handle due to low specific weight and tendency to agglomeration (examples: technopolymers, glass fibres, Kevlar, chromite, ceramic mixtures). It ensures high precision and discharge performance as the product flows towards the outlet according to the First-in First-out principle, facilitating the discharge of hoppers and silos of different capacities and preventing segregation of the material. It is used as a Mass Flow Meter.

Main advantages

• gentle product handling thanks to slow blade rotation
• precise and even dosing
• prevention of bridging and ratholing phenomena of sticky powders during the dosing or discharge process
• adjustable feed flow via inverter on the motor
• low drive power
• reduced noise and vibrations
• possibility of adding multiple discharge outlets (on request)
• reduced and simplified maintenance

Applications and versions
Various models are available depending on the material to be processed. Special versions are available for hygienic and explosive (ATEX) environments and with diameters larger than the standard ones for direct coupling to silos.
