Observing the Motion of Seed Coat Fragments on a Saw-Type Lint Cleaner

Controlled-batt saw-type lint cleaners use grid bars to remove foreign material from cotton fiber such as leaf particles, motes, grass, bark, and seed coat fragments.  Video was taken with a high-speed camera of seed coat fragments colliding with experimental grid bars on a full-size conventional lint cleaner.  A prism mounted on one of the grid bars showed simultaneous views in the radial and axial directions of fiber and seed coat fragments striking the grid bar.  The analysis will compare different designs and configurations of grid bars as well as different grid bar-to-lint cleaner saw clearances.
