Method and device for producing wood shavings

A method for producing wood chips for the production of chipboards, comprising

• a material supply unit (4) in at least one first carrying structure (3, 4a) that is adapted to the material supply unit (4),
• a first mechanical sorting unit (6), the material to be comminuted a first time in at least one second carrying structure (3, 6a) that is adapted to the first sorting unit (6),
• a material comminution unit (8) in at least one third carrying structure (3, 8a) that is adapted to the material comminution unit (8),
• a second mechanical sorting unit (10), the comminuted material to be comminuted a second time in at least one fourth carrying structure (3, 10a) that is adapted to the second sorting unit (10),
• wherein the first, second, third, and fourth carrying structures (3, 4a, 6a, 8a, 10a) are each arranged 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 (20, 22, 24, 26), wherein the supplied material is conveyed from the material supply unit (4) through a first material-carrying line (20) to the first mechanical sorting unit (6) and is sorted, and is supplied from the first mechanical sorting unit (6) through a second material-carrying line (22) to the material comminution unit (8) and is comminuted therein so as to form wood chips, and is supplied from there through a third material-carrying line (24) to the second mechanical sorting unit (10), in which the wood chips are sorted by machine, whereupon the wood chips are provided for the production of chipboards.
