This rice length grader machine also called Cylinder Length Grading Machine. It separate broken rice from fine ones by their length. When the length of broken ones is more than half of the fine rice, it can’t be graded by its thickness and width. Therefore, the accuracy is assured. The material come into the roller, the longer granules fall out through the hole and flow to the exit; and the short ones fall into screw propeller and pushed out of the rice length grader machine.
