The indented cylinder with cellular pockets (indents) is designed for sorting by length. Many grains, seeds, kernels and other free-flowing products, which are to be separated from each other, are of almost identical dimensions, except for their length. Thanks to these differences in length precise separations can be achieved with the indented cylinder.
Thousands of precision pockets (indents) are pressed into the special steel sheet jackets forming the cylinder. These pockets separate all the broken or shorter products. The main product and the broken grains or shorter products leave the machine through two separate outlets.
