Document Type and Number:
Japanese Patent JP7246835
Kind Code:
B2
Abstract:
This rotary crushing machine is provided with a main shaft, and a revolving member. The main shaft is supported in such a way as to be capable of spinning about an axis. The revolving member rotates, causing the axis of the main shaft to revolve. The rotary crushing machine crushes an object to be crushed by means of the movement of the main shaft resulting from the rotation of the revolving member. The rotary crushing machine is provided with a sensor for detecting the rotational speed of the spinning of the main shaft. The possibility of a bearing abnormality is detected on the basis of the rotational speed of spinning of the main shaft when the revolving member is caused to rotate at a prescribed rotational speed in a no-load condition.
