System and method of monitoring a crushing device

摘要

A monitoring system for a crushing device that provides continuos and automatic monitoring. In one embodiment of the invention, the monitoring system monitors vibration signals and sensed temperature readings to determine whether the sensed data exceeds predefined thresholds and thereby signaling an possible alarm condition. In the event of the alarm condition, an idle detector in the monitoring system determines whether the crushing device is operating in an idle state. If the crushing device is in an idle state, an alarm is signaled for operator attention and optionally the crushing device may be automatically shutdown. The monitoring system may be used with any crushing device such as cone crushers, roll crushers, jaw crushers, and impact crushers or other type crushing devices.
