FDA Stainless Steel Conveyor Return Roller For Steel Ore Industrial
Conveyor Steel Carrying Return Idler Rollers For Steel Ore Industrial
The comb-shaped roller is covered with a hard rubber ring, and the comb-shaped roller can prevent the conveyor belt from deviating. Comb-shaped rollers are used on conveyors that convey viscous materials.
This product is widely used in the original dock transporting places where dust is bigger and the environment has high corrosive , such as mining , power , steel , stone materials factory , cement and coking plant , coal washing factory , salt plant , alkali plant , fertilizer factory , dock and so on .
Factors affecting the quality of comb idlers:
1. Roller radial runout (this index directly affects the stability
of material conveying)
2. Axial string momentum (directly affects the service life of the
roller)
3. Flexibility (affecting the service life of the roller and the
service life of the tape, as well as the driving power of the whole
machine)
4. Performance (affecting the service life of rollers)
5. Dustproof performance (affecting the service life of rollers)
6. Axial bearing capacity (affecting the service life of rollers)
7. Impact resistance (affecting the service life of rollers)
8. Rotation resistance (affects the service life of the tape)
Different type of conveyor idler:
1. Flat/Carrier/Carrying Rollers: Used to handle bulk&unit
material.
2. Impact Rollers: Installed at the loading point to absorb the
shocks and to help protect against belt damage.
3. Return Rollers: Used to sustain and support the belt during its
return section and performs a cleaning action
--- Return rollers with Spaced Rings (Rubber Disc Rollers)
--- Return Rollers with Helical Rubber Rings (Spiral Rollers)
4. Self-aligning/Training Rollers: Used to adjust the belt
deviation, preventing hunting and ensuring stable operation of
conveyor belt.
--- Tapered self-aligning rollers
--- Friction self-aligning rollers

Main classification of rollers:
There are several standards for the quality of the Iron Return Disc
Conveyor Roller : the radial runout of the roller; the flexibility
of the roller; the amount of axial movement.
1. According to the material, it is divided into rubber roller,
ceramic roller, nylon roller and insulating roller.
2. There are mainly trough roller groups, various parallel roller
groups, various self-aligning roller groups, and various buffer
roller groups.
(1) Trough idlers include ordinary idlers, forward inclined idlers,
quick-change bearing idlers, hanging idlers, triple chain idlers,
reversible idlers, variable groove angle idlers, and transitional
idlers. Idler, V-shaped Idler, etc.;
(2) Parallel idlers include ordinary idlers, comb idlers, forward
inclined idlers, steel rubber idlers, spiral idlers, etc.;
(3) Self-aligning rollers include universal rollers, friction
reversible rollers, powerful rollers, cone rollers, spiral rollers,
combined rollers, etc.;
(4) Buffer rollers include spring plate rollers, buffer ring
rollers, powerful buffer rollers, adjustable elastic rollers,
hanging rollers, etc.
