Types of Idler Pulleys for Coal Conveyors

• Carrying Idlers: These are used to support the loaded conveyor belt. They are typically arranged in a trough shape to increase the carrying capacity and prevent the coal from spilling. Carrying idlers can be single - roll or multi - roll designs, depending on the width and load requirements of the conveyor.
• Return Idlers: Positioned under the return side of the conveyor belt, return idlers help to guide and support the empty belt. They are usually flat - faced and are spaced at regular intervals along the conveyor length.
• Impact Idlers: Installed at the loading points of the conveyor, impact idlers are designed to absorb the impact energy of the falling coal. They have a special construction, often with rubber rings or pads, to cushion the impact and protect the conveyor belt from damage.
