Perforated vibrating screen sheet is the best choice in unique and severe screening situations. It is made to suit the specified screening application and screening equipments.
Unlike woven wire cloth, perforated plate has a level screening surface, free from high points, which rapidly wear away in many severe screening applications. The flat screening surface and length of the screen deck can effectively separate the over-sized sliding materials from the undersized particles.
There are three hole types of the perforated vibrating screen sheet.
Square hole perforated vibrating screen is the most frequently used aperture in the vibrating screens. It can be divided into staggered pattern and straight pattern. Square hole can be directly matched to the required testing sieve openings. It can also be designed to offer the equivalent open area of wire cloth.
Different sizes for the support bars, center hold-down bars and impact areas are designed to maximize open area and increase wear-life of both the screening plate and your vibrating screen.
Square hole staggered pattern
Thickness: 16G, 14G, 12G, 11G, 10G, 3/16”, 1/4”, 5/16”, 3/8”.
Opening size: 5/32” - 9/16”.
Bar: 3/32” - 3/8”.
Square hole straight pattern
Diameter: 11G, 10G, 3/16”, 1/4”, 5/16”, 3/8”, 1/2”, 5/8”.
Opening size: 5/8” - 7”.
Bar: 5/32” - 2”.
Round hole perforated vibrating screen is ideal for places where extreme accuracy is absolutely necessary, such as the screening anthracite and bituminous coal, metallic, ore, and in aggregate screening facilities.
The round hole offer the most consistent sizing and least open areas, regardless of the shape of the incoming materials. It is also suit to aggregate screening where plugging is prevalent. The aggregate material, which fails to pass the round openings is freely discharged due to the consistent round opening shape.
Thickness: 20G, 18G, 16G, 14G, 12G, 11G, 10G, 3/16”, 1/4”, 5/16”, 3/8”, 1/2”, 5/8”, 3/4”.
Opening size: 1/16” - 8”.
Bar: 3/64” - 1-3/4”.
Hexagonal perforated vibrating screen has maximum open area and screening efficiency. It is the best compromise between square openings and round openings where the plugging occurs. It is also a good choice where high production of accurately sized material is needed.
Thickness: 12G, 11G, 10G, 3/16”, 1/4”, 5/16”, 3/8”, 1/2”, 5/8”, 3/4”.
Opening size: 1/4” - 6”.
Bar: 1/8” - 1-1/4”.
Perforated sheet metal plate is mainly for filtration and separation. Perforated vibrating screen has superior screen surface and great performance of filtration, so it is widely used in the flowing industries:
