What Conveyor Idlers Are Suitable for Bulk Material Handling?

For bulk material handling(mining,cement,coal,grain,sand,gravel,etc.),these are the most commonly used and suitable conveyor idlers:

1.Standard Trough Idlers

Used for carrying side of the conveyor

Form a trough shape to hold bulk materials

High load capacity,widely used in most bulk handling systems

2.Return Idlers

Support the empty return belt

Simple structure,mainly used to prevent belt sagging

3.Impact Idlers

Installed at the loading point

Equipped with rubber rings to absorb impact

Protect the belt from heavy bulk materials

4.Self‑Aligning Idlers

Automatically corrects belt misalignment

Prevents material spillage during long‑distance bulk transport

5.Flat Idlers

Used for light‑duty bulk materials or temporary conveying

Simple and cost‑effective

6.Garbage/Cleaning Idlers

Prevents sticky bulk materials(sludge,ore powder)from adhering

Extends service life in harsh conditions
