WEIGH FEEDER

A weigh feeder is a type of industrial control equipment that measures the flow rate and total weight of a material being conveyed on a conveyor belt. Weigh feeders feed material at a controlled rate into a process. It is widely used in cement, steel, food processing, mining, fertilizer and chemical industries. It basically consists of a belt conveyor with a variable speed drive. The weighing system incorporated in the system would measure the flow and control the speed of the belt to get the required rate of flow. Weigh feeders are designed according to the application and are available in capacities ranging from 2TPH to about 4000TPH. The Weigh Feeder being a custom engineered equipment that finds application in continuous bulk proportioning of solids. This gravimetric feeder is operated by a closed loop control system enabling feeding at a controlled rate and exercises precise control over rate of flow based on a micro controller. The system is capable of accepting external signals from other controllers or from the process computer, depending on the extent of plant instrumentation. Each system consists of control and local panels, load cells to measure the instantaneous load, a digital tacho to sense the speed of the belt and a belt feeder conveyor shaft is driven by an AC motor coupled through the gear box.
