Open area is the surface aperture (opening) of a screening media that allows material, pulled by gravity, to pass through. The greater the open area, the greater the screening capacity.
Open area varies with the screening media type and affects the tonnage or volume of material that can be processed on a screen deck. On screen boxes with multiple decks, the relation of open area and material gradation between the decks is an important efficiency factor that needs to be balanced.
By using the highest quality wires, MAJOR is able to decrease its wire diameters, which increases open area and throughput, while providing superior wear life.
