How do these Feeders work?
The most popular type of Gravimetric feeder is the loss-in-weight feeder. This usually consists of a hopper and a feeder. As the material is discharged the system weight is reduced. The loss-in-weight controller controls the speed of the feeder. These feeders are useful for materials that vary in physical characteristics and the meter and control the rate of discharge regardless if the material changes or not.
Waithmac engineer notices that having an efficient material handling system is crucial in the solids and bulk handling industry. So they focus on gravimetric feeder many years to design a more highly reliable machine for customers.
