ABSTRACT:
A grinding mill having a rotatable grinding chamber within which is a body of elongate grinding members that have a longitudinal axis substantially longer than the maximum transverse dimension thereof. The mill is arranged in such a way as to retaining the grinding member axes substantially parallel to the grinding chamber rotational axis. The grinding members have a cross-sectional shape and a sufficient exterior surface smoothness for enabling a body of such members to tumble over and against one another in a rotating grinding chamber and to grind particulate material within the body, as well as a ratio of mass per unit of length which varies from one position to another along the length of the longitudinal axis.
