Neglecting maintenance often causes screen media wear and breakage as well as poor efficiency.
for proper operation.
Screen box diagnostics systems can help prolong media life and improve screening by checking and monitoring a machine’s health. Use a vibration analysis system to inspect the machine for balance and excessive vibration, which can lead to screen media failure or unintended machine wear. Vibration analysis systems are becoming easier to use. Some of the newest include only a single sensor, no wires and work quickly with a smartphone.
When it’s time to remove and replace the screen media, pull off the bar rail or crown liners and inspect the steel bar rails for wear or warping. Best practice is to replace the bar rail liners during each change-out for longer screen media life.
Storage Matters
Just like it’s best to keep the expensive new car out of the harsh elements to lengthen its lifespan, so too should screen media be kept out of harm’s way to maximize its effectiveness. Leaving the media in a pile near the screen box
Use a vibration sensor to optimize settings and identify equipment issues early.
structure is convenient, but can lead to wires rusting, something that can reduce durability. Another common issue is screen media on the ground simply being run over by heavy equipment. Wire screens also get damaged when stored standing upright. The best solution to prevent damage during storage is a simple rack that allows crews to hang the screens from the hooks. This prevents damage and improves accessibility by allowing personnel to find the right screen without sifting through a pile of panels. Also, keep extra panels covered and in a well-marked area out of the path of heavy equipment.
Screen On
Though minor compared to the rest of an aggregate or mining operation, producers benefit from staying proactive with screen media maintenance. From choosing the right media for the job and installing it correctly, to proper storage and preventative maintenance, treating screen panels right can mean less downtime, fewer headaches and more profits.
