Method for separating fiber and aluminum foil from aluminum foil liner waste

Abstract: The present invention relates to a method for separating fibers and aluminum foil from aluminum foil scraps by water. The method includes the following steps in sequence: a. The aluminum foil liner waste is placed in a turbulent flow of water to dissociate the aluminum foil liner and form a mixture. Slurry; b, the mixture slurry is diluted with water to become a thin mixed slurry; c, the thin mixture slurry to form a swirl, from which the aluminum foil is separated, the remaining slurry is a thin slurry; d, the thin slurry is filtered, roll, remove excess water , get a good slurry. The method does not shorten the fiber length, can produce good slurry, has no dust pollution, and is conducive to environmental protection. The recovery rate of the aluminum foil is high, the purity of the aluminum foil is high, and the particles are uniform.
