For the dosing and weighing of fines and dust-like bulk materials (in completely closed construction) the weighing dosing screwfeeders can be used. The feeding of weighing- and dosing screwfeeder is done by a rotary vane feeder or a dosing screw. Through a fixed bearing on the feeding side and the bearing of the load cell on the discharge side, influences of the material transfer are compensated. On request, the screws can also be constructed in wear-resistant material such as Hardox. This type also can be used for products with high temperatures.
