A saw-type lint cleaner equipped with a 16-inch diameter cleaning saw cylinder was compared to one with a 24-inch diameter saw cylinder individually and in combination. Based on Shirley Analyzer lint foreign matter content, the 24-D lint cleaner removed more foreign matter than did the 16-D lint cleaner when either used alone or in combination with another 16-D lint cleaner. The amount of material removed per bale by the 24-D lint cleaner was about one pound more than that removed by the 16-D lint cleaner. The 24-D lint cleaner had a higher cleaning efficiency than did the 16-D lint cleaner either when used alone or in combination with a 16-D lint cleaner. From a classer's leaf grade standpoint, the 24-D was about ½ leaf grade better than the 16-D. In terms of improvement in the color of the cotton, there was essentially no difference between the 24-D and the 16-D. The 24-D produced bales with a higher monetary value than the 16-D. The 24-D lint cleaner is superior to the 16-D lint cleaner in terms of cleaning efficiency and bale value. This study represents the response of two cottons grown near Stoneville, MS, and other cottons may respond differently.
