A Guide To Troubleshooting A Few Common Vibratory Screen Issues


In any manufacturing setting, a vibratory screen system is one of the most crucial components that is used in daily production. When the screener is used for separating fine-grained particles or refining, a flaw in the operation of the vibratory screens can lead you to a lot of hassle. Repeated processing, contamination, and lost product could all be possible problems when your vibratory screens have malfunctioned. Here are a few of the most common vibratory screen problems you should be able to recognize.

Bypass of Materials

Material bypass occurs when heavier material is allowed to pass through the screening system along with the finer particles that should be sifted out. In most cases, this is caused by damage to the screen frame that is leaving a gap. However, this can also be caused by a screen that is worn and in need of replacement. You should do a thorough walk-through of your vibratory screen system once all material has been removed to look for damaged areas.

Binding of the Screens

The vibratory screens are usually designed to allow fine materials through open spaces that are specifically sized. Screen binding is a term that is used to refer to blockages in the screen's small openings. While some binding is a normal thing, if you are having issues with screen binding daily, it could be indicative of a bigger problem. In some cases, this will be related to screens that are wrongly sized for your production needs. Too small openings will not allow the fine particles to slip through as they should. However, it could also point to issues with humidity and moisture content of the product itself or too much product being dumped on the screens at one time.

Wire Screen Failures

Beneath the first vibratory screen there is a smaller system of screens, which is set up as a secondary screening measure to catch even finer materials. This is normally caused by tears or holes in the screen itself. Unlike a single-deck screener, the dual-screen system may filter out some of the smaller particles but not all of the the lower screen is compromised.

By taking a little time to understand some of the most common problems that can arise with your vibratory screener systems, you are less likely to see lengthy downtimes when something does go wrong. Be sure to consult with your screen system's manufacturer for specific problems that you cannot troubleshoot on your own.
