Roller and beater speed combinations for higher lint out-turn in double roller gin

Abstract

The conventional double roller gin (DR) has been modified to have separate drives for roller and beater. The improvements relate to modification in the gear system of DR gin for permitting independent control on the speed of roller

and the oscillation frequency of beater. The modification leads to desired flexibility while ginning cottons with different staple lengths. This modified gin has increased the lint output by 50-80% when appropriate speeds are chosen to suit the different staple lengths. The important fibre parameters remain unaffected.
