Diagnosing screen media problems

Persistent problems with uptime and production quality can be frustrating. Aggregates and mining operations must work as quickly as they can to resolve issues and minimise losses from downtime and repairs. Common screening complications that operations face include contaminated piles, clogged screens or lower-than-expected screen media life. Knowing how to diagnose problems and find the best fix can expedite the process. By Lars Bräunling , director of product technology at MAJOR.

Screen media breakage problems may require an alternative type of screen media, but often also an examination of the vibrating screen maintenance and the installation practices of the screen media. First step: identify the problem While many problems are easily identifiable, it can be helpful to do a thorough evaluation of the process and look for any apparent screen media issues, in addition to the screen setup and equipment condition. The easiest and most sure-fire way to identify problems and solutions is to work with an OEM-certified technician
