ABSTRACT

Experiments were conducted to evaluate the cleaning of roller-ginned Upland lint at a commercial gin plant with a revolving-screen cleaner which is normally used to extract foreign matter from seed cotton. Both the cleanliness and quality of lint cotton cleaned with the revolving-screen unit were examined. An average cleaning efficiency of 12 percent was obtained with the tested machine, and composite grades were improved one-fourth to one-third grade. After cleaning, fewer samples were reduced in grade because of bark content. Studies with the revolving-screen cleaner will continue to improve its efficiency to make it acceptable as a lint cleaner in saw-ginning plants. It is hoped that this cleaner can improve fiber quality by reducing the number of saw-type lint cleaners that are now used at cotton gins.
