What Rollers Are Used in Quarry Conveyors?

Here are the most commonly used rollers (idlers) for quarry conveyors — heavy-duty, impact-resistant, and built for harsh stone, aggregate, and mining conditions:

1. Impact Idlers / Impact Rollers

Installed at loading points

With rubber rings to absorb heavy impact from rocks

Protect the belt from tearing and damage

2. Heavy-Duty Trough Idlers

Main carrying rollers for transporting crushed stone, gravel, ore

High load capacity, strong structure

Most widely used in quarries

3. Return Rollers

Support the empty return belt

Prevent sagging and extend belt life

4. Self-Aligning Idlers

Automatically correct belt misalignment

Reduce material spillage in long quarry conveyors

5. HDPE / Rubber Disc Cleaners / Comb Rollers

Remove sticky mud, dust, and fine stone powder

Reduce wear and jamming in dirty quarry environments

6. Transition Idlers

Used where the belt changes from flat to trough shape

Stable material handling at conveyor transitions
