Dust cyclones are a cost effective means of treating process air released by cotton gins. Modifications to the currently recommended cyclone design were tested to improve collection efficiency. Factors normally considered uncontrolled (dust loading and relative humidity) were included in a mixed-level fractional factorial experimental design. Pre-weighed gin trash was metered into inlet air. Exhaust air was passed through a filter that was weighed to determine dust loading and collection efficiency. Square and angled inlet modifications lowered cyclone performance. Neutral air tube and expansion chamber modifications were insignificant. Pressure drop increased linearly with increasing air entrance velocity while collection efficiency decreased slightly. Reducing entrance velocity may save energy without adversely affecting performance.
