4 star conveyor belt

The 4-star conveyor belt is among the most durable models designed for heavy-duty industrial applications under harsh operating conditions. This belt features a multilayer structure with four plies of polyester-nylon EP 125 to EP 250 fabric, cross-reinforced with abrasion-resistant rubber. The total thickness ranges from 8 to 14 millimeters, and the maximum allowable tensile strength reaches up to 1600 Newtons per millimeter of belt width. Its dry tensile strength is measured at up to 25 MPa, while in humid conditions it remains around 18 MPa. The top surface can be either smooth or patterned such as Chevron or Rough Top to prevent load slippage on inclined surfaces.

The operating temperature range for the 4-star conveyor belt spans from -30 to +120 degrees Celsius, with special models rated up to 150 degrees. This belt offers strong resistance to mineral oils, industrial grease, and surface abrasion from sharp particles. In abrasion loss testing according to ISO 4649, volume loss remains under 120 mm³. It supports continuous industrial use at speeds up to 4.5 meters per second. Common applications include mining operations, cement plants, power stations, and steel manufacturing industries. The bottom layer is typically made from tear-resistant and flame-retardant rubber compounds, increasing belt lifespan by up to 30%.
