Abstract
A mill for the comminution of particulate material by impact means including a shell rotating at super critical velocity and a gyrating mandrel. Material introduced to the mill forms a bed on the inner surface of the shell and is then crushed by the impact of the gyrating mandrel. The axis of rotation of the shell is in angularly displaced from the axis of gyration of the mandrel to transport material through the mill.
Claims15
A mill for crushing particulate material comprising:
- a rotatable shell;
- a shell drive configured to rotate the shell at a super-critical velocity such that the particulate material forms a compressed solidified layer of material retained against an inner surface of the shell by centrifugal force;
- a mandrel located within a chamber defined by the inner surface of the shell;
- and
- a gyrating drive, wherein the mandrel is mounted to the gyrating drive which imparts a gyrating motion to the mandrel;
- wherein the mandrel is free to rotate independently of the gyrating drive and move in unison with the shell and the compressed solidified layer of material, such that the gyrating motion of the mandrel is perpendicular to the inner surface of the shell and the mandrel crushes and reduces the size of the particulate materials in the layer of material through impact.
