Abstract

We produced a continuous annular-stirred bead mill (Spike mill) for trial and investigated the grinding efficiency of the mill. The Spike mill has a cylindrical rotor with regularly arranged rhombic protuberances on the surface in the grinding chamber.<BR>In this paper, we investigated the effect of various grinding factors, such as gap between the cylindrical rotor and the static vessel, height of the rhombic protuberance, circumferential speed of the rotor, filled ratio of the grinding medium, volumetric solid concentration of the grinding feed and apparent residence time, on the grinding efficiency of the Spike mill and two types of disk-stirred bead mill, which have been widely used in industry.
