Your Issue: Carryback (Disc return idler)

Carryback adheres on the belt, which causes serious material accumulation, residue build-up return rollers and belt mistracking. In addition, belt mistracking or belt-edge damage results in unscheduled downtime.

Solution: Disc return idler, conveyor belt cleaner

Issue: Carryback (material accumulation)


The material accumulation issue caused by material buildup in moist/sticky applications; plus, if the belt cleaner isn't installed, the situation will be worse. As a result of that, material accumulation and idler premature failures can lead to belt damage, belt displacement, and energy consumption.


Solution: Disc return idler

Case study.1: Before ---> After


Case study.2: Before ---> After


Due to the discs installed onto the steel roller, side by side, disc designed with self-cleaning prevents buildup on roller on return side of belt. As a consequence, the material does not adhere any more to the roller's surface; meanwhile discs protect the belt edges in cases of belt displacement. Discs are standard with rubber discs, PU discs, or ceramic discs. 

 Jimway's disc return idlers: 

 Lower operating costs 

 Less material waste 

 More productivity 

Jimway's customers are happy with our disc return idler, which improve efficiency be providing the following benefits:

3X Longer Service Life of Steel Roller

Disc return idler, which is self-clean roller, is suitable for conveying sticky, abrasive, or corrosive material.

Longer Lasting Conveyor Belt Components

Our disc return idler is stable in wide temperature range, extending the roller service life and has wet/sticky material shedding characteristic to prevent belt displacement (extend the belt service life).

Increased Productivity (Less Material Loss)

Preventing material buildup on the roller surface via less contact area with the belt and eliminating carryback to minimized maintenance cost, cleanup fee, and lower labor costs. Plus, keeping bulk material moving in the right direction through belt load zone can minimize material loss.

Lower Energy Costs

Without material accumulation, the less energy is required to get the roller moving, which keep the belt conveyor operating smoothly.

Safer Working Environment

Safer conveyor systems prevent operators fall down through material accumulation.
