Abstract

A revolving screen was designed, fabricated and had preliminary testing to separate uniform-sized plastic pellets and fine sand. The fabricated screener was successfully designed and is operable with market grade mesh 4 stainless steel screen. The wire diameter is approximately 0.0475 inches and aperture of 0.2023 inches. The cylindrical drum is 2 ft in diameter and 4 ft in length. Auxiliaries are made to better the operation. The testing involved the calculation of effectiveness at different feed flow rates and speeds of revolution using sand and uniform sized plastic pellets. Highest effectiveness were at 24kg/min and 12rpm at 99.98%. The lowest effectiveness was observed at 96kg/min and 36rpm at 91.33%. Using one-way ANOVA it is concluded that there is a significant trend of decreasing overall effectiveness of the screener as speed of revolution increases. increasing the feed rate also result in decreasing overall effectiveness of the screener. Applicabilility of the revolving screen with internal threads was assessed for certain sections of sugar processing especially in sugar crystal sizing and screening of different liquid flows.
