Below is a list of Vibrating Screen manufacturers from Erie, Pennsylvania. Vibrating screens are a type of vibratory conveyor that conveys and/or sorts bulk materials during processing. The main difference between a typical vibratory conveyor and a vibratory screen is that a vibratory screen runs materials over a sizing screen instead of a trough. Also known as a screen separator, vibrating screens are commonly used to separate smaller particles from larger particles for further processing.
