Weigh Feeders do a continuous weighing and controlling of bulk material feeding as per desired set point. In a second 30-40 weighments are done for bulk material running for desired accuracy.
The Micro controller based Weigh feeder controller receives the Weight in terms of Kg/metre. It processes these two inputs received from the field and calculates the feed rate in the form of Tons per hour (i.e. TPH). It also calculates the cumulative weight (Totalizer) of material passed over. . Set point TPH and start command can be given from the 3 locations (i.e. Local Panel , WF Panel & Master PLC) based on the selection switch (i.e. Mode of Operation). The accuracy particularly depends on the operation and consistent material spread on carrying belt.
There is a provision to adjust the Load cell height and to remove the material deposits on the conveyer (on line) to get better accuracy.
Design / capacity range: 1TPH to 500TPH
