Definitions
- the third air baffle can be extended into the peripheral area of the milling drum, whereby the air flow tangential from the second air baffle to the milling drum is also deflected in a direction running essentially parallel to the bale surface.
- Fig. 2 shows a cross section through the milling device
- a third air baffle 26 is arranged below the incoming air flow and serves to deflect the air flow in a direction essentially parallel to the bale surface 20, namely towards the milling rollers 3 and 4.
- the third air baffle plate 26 can be kinked or curved to allow deflection with the least possible pressure loss and avoiding air turbulence, taking into account the angle of incidence of the incoming flow.
- the section of the third air baffle 26 running downstream of the air duct 2 is preferably aligned parallel to the bale surface 20 and rests on this bale surface.
- the third air baffle 26 and the box formed from the first and second air baffle 22, 24 are expediently fastened to the grate bars 17.
