There are two categories of Idlers, basically Carrying Idlers and Return Idlers . However within these two categories there are a number of different Idler Sets which suit various applications. They are specifically designed to suit those operations so as to minimize friction, increase material carry and alleviate unnecessary stress on the Conveyor Belt.

Pulleys are used on Conveyors to Support and Deflect the belting through the Conveyor Structure ranging from: • Cast Iron Pulleys • Slatted Pulleys • Crowned Pulleys • Fabricated Steel Pulleys etc.

Where Return Idler Sets comprises of two rolls, a Support Frame is required which supports the Idler Pair and attaches the Idlers to the Conveyor Frame. This 2-roll design forms the Return Belt into a 'V' Trough and these Return Idler sets are referred to as 'V' Return Idlers. The Trough angle of the 'V' Return Idler is usually 10 degrees and this feature has been developed to assist with Belt training along the Return Strand. In addition to the fixed base frames for Return Idlers, Garland-Type Return Idlers are also available. Which like their equivalent Troughing Idlers are more tolerant of Conveyor Structure misalignment.

Worldwide Conveyor are Suppliers of Pulleys up to 600mm in diameter. We manufacture for and supply to the Mining and Industrial markets.

There are a Number of Different Types of Pulleys available for use on Conveyors as well as different Design Parameters for Pulleys serving Different Functions on the same Conveyor.

The Head/Drive Pulley is located at the Discharge Terminus of the Conveyor. It provides the Driving Force for the Conveyor. In order to increase Pulley life and traction, it often has a larger diameter than other pulleys. Worldwide can supply Pulleys with Hot Vulcanized Rubber Lagging. Plain or Grooved, as required by the Client. Different patterns of grooving such as Herringbone or Diamond can be provided to increase Tractive Friction under Dirty or Wet Conditions. Diamond grooves have the Advantage of being installed in any orientation, regardless of Belt direction.

a Pulley which is provided to Increase or Decrease Warp/Contact angle on the belt or nearby Pulley.  To support an empty Conveyor Belt in its return.

They also provide a Mechanism whereby the Conveyor Belt can be trained to run (track) true along the Conveyor Idlers. Generally Pulleys are located at the ends of the Conveyor Structure and at the Take-Up arrangement. Pulleys are used to transmit the Drive power into the Conveyor Belt and as such, are subjected to the Dynamic Belt Tension Forces in a Conveyor.
