A secondary impurity-removal recycling system for refining cotton is provided. A first feeding opening is set on the side of the first bin shell, in which the first drum is movably installed, and the first drum is tube shaped. A first mesh is set on the peripheral wall of the first drum, and a first scraper is set at the first feeding opening inside the first bin shell. One end of the first drum is provided with a first impurity-discharging pipe, the outer periphery of which is provided with a first annular hump. The first connecting sleeve is installed on the outer wall of the first bin shell, and the first impurity-discharging pipe is movably stuck in the first connecting sleeve through the first annular hump, and communicates with the first connecting sleeve. The first induced draft fan communicates with the first connecting sleeve through a first air duct.

An extractor cleaner for harvested cotton uses a plurality of sequential rotating saw cylinders a plurality variably and re-positionable deflector panels mounted for displacement about horizontal axes spaced from said plural rotating saw cylinders to deflect cotton and debris expelled by said plural rotating saw cylinders along separate conduits wherein said plurality of variably re-positionable deflector panels may be selectively positioned to deflect debris along one of said conduits to a discharge opening and to deflect cotton mingled with debris along said one of said conduits to a reclaim rotating saw cylinder.
