Satake Length Grader, indented cylinder type, separates one or two kinds of broken or shorter grains from whole grain by length. Broken grain or shorter grain which is more than half of the whole grain in length cannot be separated using a sieve or thickness/width grader. The Satake LRG solves this problem.

The stocks fed in to the indented cylinder are taken up by the indents of the rotating cylinder. the longer lengths of grain drop out of the indents on their way to the catch trough and the grain remaining in the indents is thrown in to the catch trough.
