<p>Grinder meant for grinding fibrous material which grinder comprises a pair of grinding blades comprising grinding surfaces in which case the first of the mentioned pair of blades is a stationary blade surface formed of grooves (13) and ridges (12) and is attached to a stator and the second of the pair of blades is a blade surface which is formed of grooves (13) and ridges (12), which is movable in relation to the previous blade surface and is attached to the rotor between which blade surfaces the grinding occurs and the mentioned ridges are adjusted to direct and control the run of the material to be ground with the attachment plane of the blade surfaces between the parallel ends (15); ( 18) of the ridges (12). The imaginary extension of the front edge of the ridges (12) of the grinding blades of the stator and the rotor is adjusted to form a sharp angle (A); (B) with the attachment plane (20); (21) of the blade surface or with the tangent (22); (23) of the attachment surface and the profile forming the ridge (12) is evenly thick.</p> |
