with own belt and drive
Weigh feeders are constructed for gravimetric dosing of various materials. AC-motors with frequency converters are used to regulate the belt speed. Depending on the set value and on the belt load the belt speed is controlled in a way to ensure that the dosing capacity corresponds exactly to the pre-set nominal value.
The simplest type is the weigh feeder for direct hopper discharge. For materials which are problematical to handle, special dosing devices such as rotary vane feeders, dosing screws, dosing rollers etc. are situated in front of the weigh feeders and are operated together with the weigh feeder in bloc control.
Depending on the nature of the bulk material the weigh feeders are of “open” design E-DBW-A, available with covered conveying channel or fully closed, and dust tight design E-DBW-H or with integrated rotary vane feeder E-DBW-A (H)-I.
