The main obstacles to efficient screening are plugging/pegging, blinding and carryover. Each can be minimized with a variety of solutions. Plugging/pegging happens when near-size particles become lodged/wedged, blocking the openings. Generally, if loose particles/rocks (“Carrots” Shape) get stuck in the media holes it is called plugging whereas if particles get jammed in the openings, it is called...
Proper screen tension is crucial for effective screening and longer screen life. Proper screen tension helps spread material across the full width of the screen. Uniform tension must be also maintained on the screen surface to prevent whipping and to maintain contact between the screen surface and the capping rubber (also called channel rubber, bucker-up rubber, etc.) on the longitudinal support (...
