• Temperature Monitoring in Bearings: Monitoring the temperature to prevent overheating and ensure longevity.
• Motor On and Off: Tracking the operation of the motor to avoid failures.
• Running Hours: Keeping a log of running hours to schedule maintenance and predict potential issues.
• Vibration Sensor Integrations: Incorporating wired vibration sensors to monitor machine health.
• Amplitude Monitoring: Measuring the amplitude to detect overloads and ensure optimal performance.

Why Focus on Solving This Problem Now

Improving screening efficiency directly impacts product quality, operational costs, and productivity. Here are the key reasons for addressing these challenges now:

• Screening Efficiency: The effectiveness of screening panels determines material separation quality, reducing waste and enhancing product quality.
• Material Flow Rate: Maintaining a steady and appropriate flow rate prevents overloading and ensures continuous operation.
• Maintenance and Downtime Reduction: Modern machines with advanced features reduce maintenance needs and downtime, optimizing productivity.

Approach and Solutions

The advanced monitoring solution implemented for the screening machines includes several standout features that differentiate it from competitors:

• Amplitude Data Collection: This system records the displacement or “stroke” of the screen deck as it vibrates, ensuring the amplitude stays within the optimal range specified by the machine’s design. This helps in identifying any deviations that could indicate potential issues.
• Vibration Sensors: Real-time amplitude monitoring using vibration sensors mounted on the screen deck or main frame. These sensors measure oscillations, providing crucial data to maintain optimal performance and prevent damage.
• Temperature Monitoring in Bearings: Continuous monitoring of bearing temperatures helps prevent overheating, thus extending the lifespan of the bearings and avoiding unexpected downtimes.
• Motor Operation Tracking: Monitoring the motor’s on/off status and running hours helps in scheduling timely maintenance and predicting potential failures.
• Integrated Wired Vibration Sensors: The integration of wired vibration sensors enhances the monitoring capabilities, providing accurate and real-time data about the machine’s health.
• Predictive Maintenance: By collecting and analyzing data from various sensors, the system can predict maintenance needs, thus preventing unplanned downtimes and ensuring continuous operation.

Results

The implementation of this advanced monitoring solution led to significant improvements:

• Enhanced Screening Efficiency: Better material separation, reduced waste, and improved product quality.
• Optimized Material Flow Rate: Steady and appropriate flow rates matched the screen’s capacity, preventing overloads and maintaining continuous operation.
• Reduced Maintenance and Downtime: The use of modern, self-cleaning screens and predictive maintenance strategies minimized clogging and shutdowns, optimizing productivity.
