Flexible Wall Feeders

The AUTOFLEX Flexible Wall Screw Feeder is ideal for controlling accurate feed of granules and dry powders, in particular those that are non-free flowing like Titanium Dioxide, Calcium Carbonates, Bakery Ingredients, Clays, Oxides, Pigments and Perlite.

This high performance screw feeder has been widely accepted into many industries including Foods, Pharmaceutical, Chemical, Agri, Paint and Pigments, Mining, Plastics and Water Treatment.

One of the unique and main features of this feeder is its synchronized flexing of the urethane hopper providing a continuous and reliable product flow with even the stickiest materials that conventional feeders struggle with. External paddle type massagers provide two flexing zones, at the top of the hopper where the product enters and at the base of the hopper where product enters the auger. This gentle massaging action prevents rat-holes and bridges forming within the hopper and therefore promotes mass flow. The paddles have two adjustments to optimize both the massaging action, the depth of the hopper flexing, and the ability to place emphasis on the top or bottom zones. This allows the feeder to be customised to suit the particular product characteristics.

Available in single or dual motor configuration, normally DC motors are installed to provide constant power over a wide range of speed variation. A remote control panel is supplied with trimpot speed adjustment and an LCD display. For hazardous or wash down areas, AC motors may be fitted with variable speed drives.

Feeders may be configured to operate in Volumetric, Loss of weight (batching) or Loss in Weight (continuous) modes.

Common applications for this feeder are under bulk bag discharge stations, feeding into or out of a weigh hopper, feeding mix tanks or directly into other processes. A range of extension hoppers are available to accommodate particular application needs.
