What Conveyor Idlers Are Used in Steel Plants?

Steel plants operate under extreme conditions: high temperature, heavy impact, heavy dust, slag, and continuous heavy load. The idlers must be high-temperature resistant, anti-abrasive, dust-proof, impact-resistant, and heavy-duty. Below are the most commonly used types.

Heat-Resistant Idlers

Essential for conveying high-temperature materials like sinter, coke, hot pellet, and hot slag. They use heat-resistant bearings and labyrinth seals to maintain stable performance in high-temperature working conditions.

Impact Idlers

Widely used at feeding points, transfer points, and furnace discharge zones. They are equipped with buffer rings or rubber discs to absorb strong impact from heavy materials, protecting the conveyor belt and extending service life.

Troughing Idlers

The most widely used on the carrying side for transporting ore, coal, sinter, and other bulk materials. They usually adopt 35° or 45° trough angles with thickened steel tubes to support heavy loads.

Self-Aligning Idlers

Used on long-distance and heavy-duty conveyor lines to automatically correct belt deviation, prevent edge wear and material spillage, ensuring stable operation.

Return Idlers

Used to support the empty return belt. They feature reliable sealing to prevent dust and slag from entering bearings, reducing resistance and maintenance.

Abrasion-Resistant & Dust-Proof Idlers

A must for steel plant environments. Multi-stage labyrinth seals and wear-resistant pipe bodies effectively block dust, scale, and slag, greatly prolonging service life and reducing downtime.
