Abstract

A screw feeder for lignocellulose-containing material, comprising a conical housing (2) with a screw (3) having a continuous thread (4) for simultaneous feeding and compression. The screw thread (4) is formed so that at least the outer portion of the feed side (10) of the thread is angular so as to form an obtuse angle ( alpha ) with the surrounding housing (2). <IMAGE>
