Conveyor & Industrial Supplies (Pty) Ltd manufacture and supply snub pulleys throughout South Africa as well as internationally.
A spiral pulley is a type of conveyor pulley that features a helical design, with the belt wrapped around the pulley in a spiral pattern rather than a straight line. The spiral design of the pulley helps to prevent the belt from slipping or coming off the pulley, particularly in applications where the belt is under tension or subject to frequent direction changes.
Spiral Pulley operational benefits
The spiral pulley works by creating a natural path for the belt to follow as it moves around the pulley. Rather than pulling the belt straight off the edge of the pulley, as a conventional pulley would do, the spiral design allows the belt to smoothly and evenly transition around the pulley, reducing the risk of slippage or damage. Spiral pulleys are typically used in conveyor systems that require high tension, heavy loads, or frequent changes in direction. They are particularly well-suited for use in agricultural, mining, and construction applications, where materials such as grain, coal, or construction debris need to be transported over long distances.
Spiral pulleys can be made from a variety of materials, including steel, aluminum, and plastic, depending on the specific needs of the application. Steel spiral pulleys are the most common, due to their durability and strength. However, aluminum and plastic spiral pulleys may be preferable in certain applications where weight or corrosion resistance are important factors.
In summary, a spiral pulley is a type of conveyor pulley that features a helical design that helps prevent belt slippage and damage. It is particularly well-suited for use in heavy-duty applications where high tension or frequent direction changes are required. Spiral pulleys can be made from a variety of materials depending on the specific needs of the application.
