An apparatus is provided for treating a fibre suspension by screening and fibre-separating mechanical working in the manufacture of papermaking pulp. The apparatus is provided with a rotor arranged within a housing, which rotor is surrounded by a stator. The inner surface of the stator cooperates with the outer surface of the rotor to define a refining gap for the treatment of the fibre suspension. The refining gap is divided into a first treating zone and a second treating zone for the processing of the fibre suspension. An adjustment member allows for adjusting the width of the refining gap within the first treating zone independently of the width of the refining gap within the second treating zone. The refining gap within both the first and second treating zones may be simultaneously adjusted by axial displacement of the rotor.
