Optimizing the speed of the cleaning cylinder on the Batt-Less Lint Cleaner

An experiment was run to determine the optimum speed of the cleaning cylind er on the Batt-Less Lint Cleaner The Batt-Less Lint Cleaner is an experimen tal machine that combines the roller-ginning and lint-cleaning functions in to one unit. The ginning section of the machine is a standard roller gin st and, while the lint. cleaning section consists of a saw-type cleaning cylin der Because the ginned fiber is guided directly onto the cleaning cylinder without forming a batt, a feed-roll/feed-bar assembly (which damages the fi ber) is not needed. The control treatment of the experiment bypassed the cl eaning cylinder of the Batt-Less Lint Cleaner and instead cleaned the fiber with mill-type/air-jet lint cleaners. The experimental treatments varied t he speed of the cleaning cylinder from 300 to 1050 rpm in increments of 150 rpm. Results show that as the speed of the cleaning cylinder on the Batt-L ess Lint Cleaner increased, lint trash content decreased, opening and clean ing waste (prior to carding) decreased, lint loss increased, and cleaning e fficiency increased Lint turnout and bale value were not significantly diff erent due to treatment. With the exception of color grade, very short fiber s, and 36s yam strength, all other fiber and yam properties were not signif icantly different due to treatment, and all were at acceptable levels. Base d on the results of the experiment, the optimum speed of the cleaning cylin der was found to be between 750 and 900 rpm.
