The discharge auger is used to stop material coming to the hammer/flail mill when it is overloaded and to ensure smooth filling to the mill, by regulating the speed by use of a frequency inverter.
The auger brings the material to the outlet of the auger where the material is going into the straw scratcher. It is the TDA auger and the speed of these augers that sets the material flow on the line. Both auger are always flooded with materil. In case of blocking in the augers due to wet or difficult material, can these augers both individually reverse for a period of 1-2 sec. (max ), and here after run forward again.
