Fine opener is one of the core machines in a blowroom line, belonging to the fine opening and cleaning process. It primarily performs further fiber opening, combing, and efficient removal of impurities, delivering high-quality, clean cotton layers for subsequent processes such as carding. The machine features a compact structure, mainly composed of five modules: upper cotton box, feeding unit, beater unit, grid adjustment unit, and frame. Waste material is discharged through centrifugal force generated by the rotating beaters. After thorough opening and cleaning, the raw material is conveyed to downstream processes, while waste is drawn into the filtration system.
