Abstract (en)
[origin: WO2022084031A1] According to the invention, in order to provide a method which allows for improved provision of wood shavings, a method for producing wood shavings for the manufacture of particle boards, in particular made from recycled wood, comprises: supplying material in at least one first carrier structure; automatically sorting the material to be comminuted a first time in at least one second carrier structure; comminuting the material in at least one third carrier structure; and automatically sorting the comminuted material a second time in at least one fourth carrier structure; wherein the first, second, third and fourth carrier structures are each located so as to be semi-mobile on a foundation and/or on a supporting structure and are interconnected either directly or via material-carrying lines, wherein the supplied material is conveyed from the material supply unit through a first material-carrying line to the first automatic sorting unit and is sorted, and is supplied from the first automatic sorting unit through a second material-carrying line to the material comminution unit and is comminuted in the latter to form wood shavings, and is supplied from there through a third material-carrying line to the second automatic sorting unit in which the wood shavings are automatically sorted, whereupon the wood shavings are provided for the manufacture of particle boards. The invention also relates to a device for carrying out the method.
