Dosing device comprising a tiltable crusher plate.

摘要

Dosing device (1) for powdery or granular material comprising a hopper (3) for the material (2) to be dosed, a drivable transport member (5) adjoining a delivery side of said hopper (3) and bounding a passage (7) together with a wall (6) of the hopper (3), tilting means (20) and a crusher plate (19) connected through the tilting means (20) with the wall (6), extending at least from the passage (7) towards the interior of the hopper (3) and diverging with respect to the transport member (5). Preferably the crusher plate (19) extends across the passage (7). During dosing the material lumps jammed between the transport member (5) and the crusher plate (19) are broken up by the tilting movement of the crusher plate (19) and conducted away, and by the return movement of the crusher plate (19) a break-up effect is applied to the larger lumps residing upstream under the crusher plate (19).
