IMPROVEMENTS FOR COTTON GIN TRASH CYCLONES

Thirteen cyclone trash exit arrangements were evaluated using a conven tional 1D3D cyclone and gin trash from stripper-harvested cotton. Four of the experimental arrangements outperformed the standard cyclone co nfiguration. Superior arrangements included an. air bleed system that extracted 9% of the process air along with the trash, a linear Fight d esign discharging into a vented trash system, a large expansion chambe r discharging into a sealed trash system, and a spiral Fight design di scharging into a Sealed system. Of these arrangements, the large expan sion chamber appeared to be the most practical candidate for retrofitt ing an existing gin's cyclone system.
