A disc housing intended for refiners with refining discs (1,2) rotating in opposed direction relative to each other for mechanically disintegrating and working fibrous material, where the disc housing (3) air-tight surround the refining discs (1,2) and is provided with an outlet (8) for the worked fibrous material. The inside of the disc housing (3) along its periphery is formed with a channel (10), which has, seen in circumferential direction, a continuously increasing radius , which increases all the way to the outlet (8), which is located tangentially in a direct continuation of the channel (10).
