How Loss in weight feeder work

A Loss-in-Weight feeder operates by continuously weighing the material being fed into a process, and controlling the feed rate to maintain a desired setpoint. The feeder consists of a hopper that holds the material, a conveyor or feeding mechanism to move the material, and a scale to continuously weigh the material. The control system uses the weight measurement to calculate the feed rate and adjusts the feeding mechanism to maintain a constant rate. This type of feeder is commonly used in processes where a precise and consistent feed rate is required, such as in food processing, chemical production, and pharmaceutical manufacturing.
