VRM ONLINE SUPPORTSOLUTION FAR BEYOND CLASSICAL CONDITION MONITORING
VRM Online Support
Instant Alarm Root cause Analysis
The VRM Online Support combines a classical condition monitoring system with unique services in terms of elaborateness and data preparation. Loesche collaborates with DALOG a family owned and independent monitoring specialist which provides customized solutions since 1998. Over 200 plants worldwide are equipped with DALOG. The concept itself consists of 3 levels. The condition monitoring system builds the foundation. Next stage is the torque measurement system at the input shaft and finally the Process Monitoring which records mill operation parameters in high resolution. Our System puts data into context and offers a solution for classical maintenance planning but also process optimization and root cause analysis.

Core element of the concept is the gearbox which is monitored by a multi-sensor online system. Next stage is the torque measurement system to precisely capture the dynamics during mill operation that are applied onto the gearbox elements. The System will send instant alarms to the CCR if the torque signal runs out of line. The next superior level represents the grinding process as the origin of dynamics. In combination with the torque signal it is possible to correlate the outcomes of both measurements to detect the root cause of high dynamics. The outer shell represents our online solution.

ConditionSensors:• Speed• Acceleration• Displacement• Temperature
All sensors such as Speed Sensors, Acceleration Sensors, Displacement Sen-sors and Temperature Sensors are mounted inside or onto the gearbox housing. The Torque Sensors is applied directly on to the input shaft and creates the signal via strain gauges. All sensors are connected to a junction box and communicate via fieldbus with the PLC. The collected data will be transferred via VPN connection for further processing.
The CCR interface enables the operator to check the status of every single Sensor at any time and to react on instant alarming.
With the evaluation software process engineers can correlate multiple process parameters to find the root cause of unstable process conditions and high dynamics during operation
The report itself follows a coherent structure. Starting off with a summary of all gearbox signals, followed by torque alarms and eventually the correlation of torque signals and process parameters.
The client will receive 6 reports per year as well as a Loesche quotation-pack-age with recom-mended spare parts and addi-tional supply.
