Abstract (en)
Method of producing a board containing wood chips from a wood-based starting material. According to the method, the starting material is disintegrated into wood chips of a preselected size for producing a mass, and then the mass containing wood chips is used for forming a board. According to the invention, the starting material is disintegrated with a continuous flow mixer (1) operating according to the impact mill principle, said mixer having at least two milling rotors, one inside the other (4-7, 10, 11), having milling vanes (10, 11), at least one of the rotor being rotatable and at least a part of the vanes (1) of the outermost milling rotor being disposed in an angular position with regard to the radial direction of the rotor. With the help of a disintegrator of the impact mill type, it is possible to continuously regulate the result of the milling/disintegration.
