Double-Weave woven wire from Montreal-based Major Wire Industries Limited is constructed of two, side-by-side, lighter-gauge wires to outperform heavy-gauge, single-strand woven wire and perforated punch plate in high-impact applications.
Impact from large aggregate material can cause screen breakage with even the heaviest single wire gauges. Woven with two smaller-diameter wires, Double-Weave screen media has lower wear points than larger, single-strand wire; one wire helps preserve the life of the other as it wears.
The combined tensile strength of the two finer-gauge wires withstands up to four times greater impact providing up to 40 percent greater wear life than that of one heavy-gauge wire, making Double-Weave ideal for scalping applications and top screen decks, according to Major Wire Industries Limited.
Double-Weave also weighs less and is more flexible than single heavy-gauge screen media, so it is easier and safer to install, according to the manufacturer. Compared to perforated punch plate, Double-Weave has far more open area, increases throughput up to 50 percent without costly screen deck alterations and costs up to 25 percent less.
