Reliability Centered Maintenance (RCM) for the cement

Reliability-Centered Maintenance (RCM) is the process for determining a more effective maintenance approach. RCM’s philosophy employs preventive maintenance (PM), predictive maintenance (PdM), real-time monitoring (RTM1), fault execution (RTF, also called reactive maintenance), and proactive maintenance techniques in an integrated manner to increase the likelihood that a machine or
