WFS1 Closed type Belt Weighing Feeder is used for continuous weighing and feeding powder materials, which can be applied in cement, chemicals, coal, food, fertilizer and other industries.

Principle:
The electrical weighing device is installed under the belt, when the material works on the load cell which can generate a signal in proportion to the material weight and the signal is transmitted to the controller. At the same time, the speed sensor installed on the tail pulley detects the belt speed and generates a signal which is also transmitted to the controller. By multiplying the weight signal and the speed signal, the instantaneous flow rate and total accumulation can be calculated.
