The APS threshing system operates so efficiently that only about 10% of the grains run through the residual grain separation stage in the LEXION. 90% of the grains have already been separated from the straw by APS.
The even flow of straw on the open-bottomed straw walkers with an extreme gradient angle ensures that practically all the grain is separated from the straw.
A separate returns pan sends the grains on their way to the preparation floor.
Residual grain separation occurs on a total length of 4400 mm across four straw walker steps. The LEXION 670/660/650 models are equipped with six straw walkers and the LEXION 630/620 models with five. Centre and side extensions are available. Even large volumes of straw are transported quickly and easily.
