How to prevent linear vibrating screen from clogging

Preventing a linear vibrating screen from clogging is a critical operational challenge. Clogging, also known as blinding (when fine, sticky particles block the apertures) or pegging (when near-size particles get stuck in the apertures), severely reduces efficiency, lowers product quality, and increases downtime for cleaning. How To Prevent Linear Vibrating Screen From Clogging The solution is rarely […]
