Materials is dissolved/broken up in its strokes/bale stamps and is moved over the horizontal bale breaking auger.
The blades/knifes press the material against a flexible shear bar that holds back the material and prevents the material from blocking. After the shear bar is the material entering down into a metering auger, this can also be delivered as a free opening.
Stones and other contamination in the straw is falling into the bottom of the machine and transported below under where the straw enters the horizontal bale breaking auger, here is made an opening in which stones and other foreign objects is pushed into as collection stone trap. A level sensor in the top of the machine controls the feed table and prevents the machine from being overfilled.
