Strategies to maximize your screen’s productivity
Some manufacturers use vibration analysis technology to offer impact testing – or a bump test – to ensure proper machine calibration and promote efficient operation. Impact testing involves striking the machine at key points with a dead blow hammer while the machine is off.
Vibration analysis sensors are placed at key locations on the vibrating screen while a technician tests the natural frequency of a machine. Based on the results, engineers can adjust machine parameters to avoid operating in resonance, which can diminish productivity, incur damage to vibrating screens and pose safety risks.

It is important to note that natural frequency can shift over time as components are repaired or replaced, so the impact test should be conducted regularly. By incorporating impact testing into an operation’s regular maintenance routine, producers can ensure optimum screening performance and equipment reliability.
Another advanced diagnostic tool is condition monitoring, which is designed to monitor the health of vibrating screens using modern algorithms and artificial intelligence. The system utilizes permanent sensors that monitor the equipment 24/7 to capture real-time information and provide alerts via email immediately upon the first sign of a potential problem.
By constantly monitoring the accelerations of the vibrating screen, some systems can even forecast the equipment’s dynamic condition in regular intervals. With consistent use, condition monitoring software will accurately point out and predict critical issues and advise when to schedule maintenance, along with what to focus on during that planned downtime.
By using diagnostic programs to conduct regular analysis and by engaging in predictive and preventive maintenance, operations will see minimized downtime through faster problem-solving, lower repair costs and increased peace of mind.
Increase profits
The development of the double eccentric screen and other screening technology provides operations with innovative and cost-effective ways to increase their profits and efficiency. By integrating the right equipment, screen media and vibration analysis systems, producers can see more uptime, higher-quality results, increased productivity and greater profits.
