ABSTRACT:
A method for the separation of granulate and water in an after-treatment section following a granulator in which a vibrating screen receives the water and granulate mixture. In order to obtain low residual moisture without subsequent drying, the granulate-water mixture on the screen is subjected briefly to a vacuum over the entire width of the vibrating screen at longitudinally spaced locations, in alternation, from above and below the screen within the first third of the length of the screen.
