Loss-in-weight feeders are used when high accuracy is required and when it is necessary to display (by weight) the feed rate, the weight in the hopper, and the total amount fed. These feeders can be employed in continuous or batch modes.
FlexWall® Feeder
 

Brabender - FlexWall FeederThe Loss-in-Weight Flexwall Feeder is chosen for applications requiring the metering of dry ingredients at weight-controlled rates. The Standard Loss-in-Weight Flexwall feeder incorporates onto its weigh frame a standard flexwall feeder. The flexwall feed mechanism comes complete with a paddle-agitated polyurethane hopper and variable speed screw system to aid in providing precise gravimetric (weight controlled) feeding of powder, pellet and fibrous materials. This feeder features easily changeable agitation amplitude and frequency, as well as easy removal of hopper for cleaning.

Dosing Screw Feeder Single/Twin Screws
  Brabender - Dosing Screw FeederThe Dosing Screw Feeder is recommended for ingredients that have one or more of the following characteristics:
- Floodable and sticky powders particularly at low rates
- Ingredient temperatures above 80ºC
- Where all stainless steel construction on contact parts is required
- For "energetics" (explosive ingredient) applications
Vario Modular Feeder
  Brabender - Vario Modular FeederThe Vario Modular Feeder is designed for gravimetric feeding of both well and poorly flowing bulk ingredients ranging from powders to fibers. It consists of a system of standard modules for variable combination such as weighing modules, feed modules, hopper modules and agitator modules as well as a free-standing mounting base. Different module configurations allow ingredient specific design and maximum production flexibility. Suitable for applications where a single feeder is needed to feed more than one ingredient.
Ingredients: All, including floodable powders
Operation: Interchangeable feed modules, vertical agitator option
Max. Feed Rate: 333 cu.ft./hr.
Feed Modules: Single, twin screw
Vibrating tube, tray
Special Features: For processes requiring fast changeover of various ingredient types. Suspended scale for high accuracy.
Liquid Loss-In-Weight Feeder
  Brabender - Liquid Loss-In-Weight FeederThe Liquid Loss-in-Weight Feeder weighs and controls the flow of a continuously pumped liquid. This superior feeder is very accurate because it measures actual weight. Models are available for feed rates between 10 grams per hour and 10,000 lbs per hour to within feed rate accuracies of ±0.1%. These feeders are not only precise but versatile and can control and meter even difficult liquids which are hot, viscous or slurried and add them to dry ingredients reliably and consistently. Pumps are selected to match specific ingredients. Weigh tanks are specially designed for each application.
