Abstract
A method, with its corresponding apparatus, for pulping and sorting waste material, especially waste paper, into a separator of the type having a chamber defined by a cylindrical wall, a first end wall provided with a perforated screen and a second one end wall facing said first end wall and including, in addition, an impeller in said chamber adjacent to said first wall, characterized by introducing material through an intake in the axial center of said second end wall, separating light weight impurities through an opening of said chamber in an area proximate said first end wall and separating the heavy rejects from an outlet of said chamber in an area proximate said second end wall.
