Delta Specifications

Plied Belts with Rubber Covers

Utilization: Transportation of bulk or other material, various mining and industrial sectors, such as: quarries,opencast mines, power plants, cement industry, steel, ports, paper and wood, glass, any standard use.

Tensile Strength: 250 N/mm to 2000 N/mm - using 2 to 5 plies

Width: Standard 1600 mm maximum. We can supply wider belts if required. Tolerance +/- 1%

Belt Structure: The DELTA belt textile carcass is made up of layers of fabrics, from 2 to 4 (or more) plies. Each of these is separated by a rubber layer. This "sandwich" structure enables the belt to absorb shocks. The upper and lower fabrics of the belt are then covered with a final rubber cover.

Main Mechanical Properties: The fabric consists of polyester (E) yarn in the warp direction to minimise the stretch of the belt and polyamide (P)

Belt Stretch: Yarn in the weft direction for good belt flexibility.

Adhesion: at 10% of belt nominal tensile strength: 1.5% max
The fabrics are dipped with RFL solution. The RFL and rubber composition is designed to ensure maximum adhesion between the plies. This needs to be adhesive high enough to ensure a long life expectancy, but not so adhesive that it would hamper the operation of splicing the belt.
