occupational cotton dust control technology was evaluated in 10 oil mills throughout the cotton belt of the u. s. this evaluation was restricted to mechanical portions of each mill: seed cleaning, delintering, hulling and separating, and linter baling. based on the process machinery observed in these mills, a 500 ton/day model cottonseed oil mill was designed. the occupatonal dust control systems for this mill were based on current state-of-the-art technology observed during this project. further improvements based on readily available air pollution control devices have been incorporated. the dust control system includes coarse dust removal by high-efficiency cyclones whose effluent discharges into pulse-jet fabric filter baghouses operated at an air-to-cloth ratio of 20:1. 6 refs
