Abstract: A centrifugal ball mill has a cylindrical container in which an object to be crushed and a crushing ball are contained, a revolution mechanism that revolves the container about a revolution axis, and a rotation mechanism that rotates the container about a rotation axis. Furthermore, the centrifugal ball mill has an inclination mechanism that inclines an inner periphery face relative to the rotation axis such that a position where centrifugal force acting due to revolution about the revolution axis is maximum in the inner periphery face changes in an axial direction of the container as the container rotates about the rotation axis, and such that the crushing ball moves in a circumferential direction and the axial direction of the container to describe a trajectory of a three dimensional Lissajous curve.

Abstract: A failure diagnostic apparatus for use in a ball screw conveyer includes a bearing stopper placed in contact with a bearing supporting a ball screw, a sensor unit equipped with an elastic member and a heat flux sensor, and a malfunction detector. The heat flux sensor works to produce an output as a function of deformation or displacement of the bearing stopper. The malfunction detector works to analyze the output from the heat flux sensor to detect a failure in operation of the ball screw conveyer. This enables a malfunction of the ball screw conveyer to be detected quickly and accurately.
