摘要： A disc housing intended for refiners with refining discs rotating in opposed directions relative to each other is disclosed for mechanically disintegrating and working fibrous material. The disc housing surrounds the refining discs in an air-tight manner, and is provided with an outlet for the worked fibrous material. The inside of the disc housing along its periphery is formed with a channel, which, as seen in the circumferential direction, has a continuously increasing radius, which increases all the way to the outlet, which is located tangentially as a direct continuation of the channel.

摘要： A feed screw for feeding lignocellulosic material to a rotary disc refiner is disclosed. The feed screw includes at least one peripheral thread for feeding the lignocellulosic material axially towards the disc refiner and the feed screw feeds the lignocellulosic material from its upstream end towards its downstream end through the center of the opposed grinding surfaces of the disc refiner, the downstream end of the peripheral thread including an angled end part disposed at an angle with respect to the peripheral thread such that the lignocellulosic material is redirected in a radial direction as it leaves the end of the peripheral thread.
