The distribution pipe is of narrowing circular cross-section with an elongated aperture. The pulp guide is mounted via a tongue and groove connection on the pipe to both sides of the aperture in order to hold the pipe together against the peripherally operative tangential force of the pipe. The plates which form the throat can be replaced from time-to-time to change the size of the throat.
